6. DISPLAY AND OPERATION 6.8.4 Motor-less operation Without connecting the servo motor, you can provide output signals or monitor the status display as if the servo motor is running in response to external input signals. This operation can be used to check the sequence of a host programmable controller or the like. (1) Operation After turning off the signal across SON-SG, choose motor-less operation. After that, perform external operation as in ordinary operation.
7. GENERAL GAIN ADJUSTMENT 7. GENERAL GAIN ADJUSTMENT POINT For use in the torque control mode, you need not make gain adjustment. 7.1 Different adjustment methods 7.1.1 Adjustment on a single servo amplifier The gain adjustment in this section can be made on a single servo amplifier. For gain adjustment, first execute auto tuning mode 1. If you are not satisfied with the results, execute auto tuning mode 2, manual mode 1 and manual mode 2 in this order.
7. GENERAL GAIN ADJUSTMENT (2) Adjustment sequence and mode usage START Usage Interpolation made for 2 or more axes? Yes Interpolation mode No Operation Allows adjustment by merely changing the response level setting. First use this mode to make adjustment. Auto tuning mode 1 Operation Yes No OK? No OK? Yes Auto tuning mode 2 Operation Yes OK? Used when the conditions of auto tuning mode 1 are not met and the load inertia moment ratio could not be estimated properly, for example.
7. GENERAL GAIN ADJUSTMENT 7.2 Auto tuning 7.2.1 Auto tuning mode The servo amplifier has a real-time auto tuning function which estimates the machine characteristic (load inertia moment ratio) in real time and automatically sets the optimum gains according to that value. This function permits ease of gain adjustment of the servo amplifier. (1) Auto tuning mode 1 The servo amplifier is factory-set to the auto tuning mode 1.
7. GENERAL GAIN ADJUSTMENT 7.2.2 Auto tuning mode operation The block diagram of real-time auto tuning is shown below. Load inertia moment Automatic setting Command Control gains PG1,VG1 PG2,VG2,VIC Current control Servo motor Encoder Current feedback Set 0 or 1 to turn on. Gain table Switch Load inertia moment ratio estimation section Position/speed feedback Speed feedback Parameter No. 34 Load inertia moment ratio estimation value Parameter No.
7. GENERAL GAIN ADJUSTMENT 7.2.3 Adjustment procedure by auto tuning Since auto tuning is made valid before shipment from the factory, simply running the servo motor automatically sets the optimum gains that match the machine. Merely changing the response level setting value as required completes the adjustment. The adjustment procedure is as follows. Auto tuning adjustment Acceleration/deceleration repeated Yes Load inertia moment ratio estimation value stable? No Auto tuning conditions not satisfied.
7. GENERAL GAIN ADJUSTMENT 7.2.4 Response level setting in auto tuning mode Set the response (The first digit of parameter No.2) of the whole servo system. As the response level setting is increased, the track ability and settling time for a command decreases, but a too high response level will generate vibration. Hence, make setting until desired response is obtained within the vibrationfree range.
7. GENERAL GAIN ADJUSTMENT 7.3 Manual mode 1 (simple manual adjustment) If you are not satisfied with the adjustment of auto tuning, you can make simple manual adjustment with three parameters. 7.3.1 Operation of manual mode 1 In this mode, setting the three gains of position control gain 1 (PG1), speed control gain 2 (VG2) and speed integral compensation (VIC) automatically sets the other gains to the optimum values according to these gains.
7. GENERAL GAIN ADJUSTMENT (c)Adjustment description 1) Speed control gain 2 (parameter No. 37) This parameter determines the response level of the speed control loop. Increasing this value enhances response but a too high value will make the mechanical system liable to vibrate. The actual response frequency of the speed loop is as indicated in the following expression.
7. GENERAL GAIN ADJUSTMENT (c) Adjustment description 1) Position control gain 1 (parameter No. 6) This parameter determines the response level of the position control loop. Increasing position control gain 1 improves track ability to a position command but a too high value will make overshooting liable to occur at the time of settling.
7. GENERAL GAIN ADJUSTMENT (b) Manually adjusted parameters The following parameters are adjustable manually. Parameter No. Abbreviation 6 36 PG1 VG1 Name Position control gain 1 Speed control gain 1 (2) Adjustment procedure Step 1 2 3 4 5 6 7 Operation Description Set 15Hz (parameter No. 2: 010 ) as the machine resonance frequency of response in the auto tuning mode 1. During operation, increase the response level setting (parameter No. 2), and return the setting if vibration occurs.
7. GENERAL GAIN ADJUSTMENT 7.5 Differences in auto tuning between MELSERVO-J2 and MELSERVO-J2-Super 7.5.1 Response level setting To meet higher response demands, the MELSERVO-J2-Super series has been changed in response level setting range from the MELSERVO-J2 series. The following table lists comparison of the response level setting. Parameter No.

8. SPECIAL ADJUSTMENT FUNCTIONS 8. SPECIAL ADJUSTMENT FUNCTIONS POINT The functions given in this chapter need not be used generally. Use them if you are not satisfied with the machine status after making adjustment in the methods in chapter 7. If a mechanical system has a natural resonance point, increasing the servo system response level may cause the mechanical system to produce resonance (vibration or unusual noise) at that resonance frequency.
8. SPECIAL ADJUSTMENT FUNCTIONS You can use the machine resonance suppression filter 1 (parameter No. 58) and machine resonance suppression filter 2 (parameter No. 59) to suppress the vibration of two resonance frequencies. Note that if adaptive vibration suppression control is made valid, the machine resonance suppression filter 1 (parameter No. 58) is made invalid. Machine resonance point Mechanical system response level Frequency Notch depth Frequency Parameter No. 58 Parameter No.
8. SPECIAL ADJUSTMENT FUNCTIONS POINT If the frequency of machine resonance is unknown, decrease the notch frequency from higher to lower ones in order. The optimum notch frequency is set at the point where vibration is minimal. A deeper notch has a higher effect on machine resonance suppression but increases a phase delay and may increase vibration. The machine characteristic can be grasped beforehand by the machine analyzer on the MR Configurator (servo configuration software).
8. SPECIAL ADJUSTMENT FUNCTIONS (2) Parameters The operation of adaptive vibration suppression control selection (parameter No.60). Parameter No. 60 Adaptive vibration suppression control selection Choosing "valid" or "held" in adaptive vibration suppression control selection makes the machine resonance suppression filter 1 (parameter No. 58) invalid. 0: Invalid 1: Valid Machine resonance frequency is always detected to generate the filter in response to resonance, suppressing machine vibration.
8. SPECIAL ADJUSTMENT FUNCTIONS 8.5 Gain changing function This function can change the gains. You can change between gains during rotation and gains during stop or can use an external signal to change gains during operation. 8.5.1 Applications This function is used when. (1) You want to increase the gains during servo lock but decrease the gains to reduce noise during rotation. (2) You want to increase the gains during settling to shorten the stop settling time.
8. SPECIAL ADJUSTMENT FUNCTIONS 8.5.3 Parameters When using the gain changing function, always set " 4 " in parameter No.2 (auto tuning) to choose the manual mode of the gain adjustment modes. The gain changing function cannot be used in the auto tuning mode. Parameter Abbrevi No. ation Name Unit Description Position and speed gains of a model used to set the response level to a command. Always valid.
8. SPECIAL ADJUSTMENT FUNCTIONS (4) Gain changing selection (parameter No. 65) Used to set the gain changing condition. Choose the changing condition in the first digit. If you set "1" here, you can use the gain changing (CDP) external input signal for gain changing. The gain changing (CDP) can be assigned to the pins using parameters No. 43 to 48. Parameter No. 65 Gain changing selection Gains are changed in accordance with the settings of parameters No.

14. COMMUNICATION FUNCTIONS 14. COMMUNICATION FUNCTIONS This servo amplifier has the RS-422 and RS-232C serial communication functions. These functions can be used to perform servo operation, parameter changing, monitor function, etc. However, the RS-422 and RS-232C communication functions cannot be used together. Select between RS422 and RS-232C with parameter No.16. (Refer to section 14.2.2) 14.1 Configuration 14.1.

Servo amplifier MITSUBISHI CHARGE To CN3 RS-232C Controller such as personal computer (2) Cable connection diagram Wire as shown below. The communication cable for connection with the personal computer (MRCPCATCBL3M) is available. (Refer to section 13.1.4) Personal computer connector D-SUB9 (socket) (Note 2) 15m (49.
14. COMMUNICATION FUNCTIONS 14.2 Communication specifications 14.2.1 Communication overview This servo amplifier is designed to send a reply on receipt of an instruction. The device which gives this instruction (e.g. personal computer) is called a master station and the device which sends a reply in response to the instruction (servo amplifier) is called a slave station. When fetching data successively, the master station repeatedly commands the slave station to send data.
14. COMMUNICATION FUNCTIONS 14.2.2 Parameter setting When the RS-422/RS-232C communication function is used to operate the servo, set the communication specifications of the servo amplifier in the corresponding parameters. After setting the values of these parameters, they are made valid by switching power off once, then on again. (1) Serial communication baud rate Choose the communication speed. Match this value to the communication speed of the sending end (master station). Parameter No.
14. COMMUNICATION FUNCTIONS 14.3 Protocol POINT Whether station number setting will be made or not must be selected if the RS-232C communication function is used. Note that choosing "no station numbers" in parameter No. 53 will make the communication protocol free of station numbers as in the MR-J2-A servo amplifiers. Since up to 32 axes may be connected to the bus, add a station number to the command, data No., etc. to determine the destination servo amplifier of data communication.

14. COMMUNICATION FUNCTIONS 14.5 Error codes Error codes are used in the following cases and an error code of single-code length is transmitted. On receipt of data from the master station, the slave station sends the error code corresponding to that data to the master station. The error code sent in upper case indicates that the servo is normal and the one in lower case indicates that an alarm occurred.
14. COMMUNICATION FUNCTIONS 14.7 Time-out operation The master station transmits EOT when the slave station does not start reply operation (STX is not received) 300[ms] after the master station has ended communication operation. 100[ms] after that, the master station retransmits the message. Time-out occurs if the slave station does not answer after the master station has performed the above operation three times.
14. COMMUNICATION FUNCTIONS 14.9 Initialization After the slave station is switched on, it cannot reply to communication until the internal initialization processing terminates. Hence, at power-on, ordinary communication should be started after. (1) 1s or more time has elapsed after the slave station is switched on; and (2) Making sure that normal communication can be made by reading the parameter or other data which does not pose any safety problems. 14.

15. ABSOLUTE POSITION DETECTION SYSTEM 15.5 Signal explanation When the absolute position data is transferred, the signals of connector CN1 change as described in this section. They return to the previous status on completion of data transfer. The other signals are as described in section 3.3.2. For the I/O interfaces (symbols in the I/O Category column in the table), refer to section 3.6. Code Pin No.

(2) Parameter setting "in parameter No. 1 of the servo amplifier and switch power off, then on. Set "1 (3) Resetting of absolute position erase (AL.25) After connecting the encoder cable, the absolute position erase (AL.25) occurs at first power-on. Leave the alarm as it is for a few minutes, then switch power off, then on to reset the alarm.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.7 Absolute position data transfer protocol POINT After switching on the ABS transfer mode (ABSM), turn on the servo-on signal (SON). When the ABS transfer mode is off, turning on the servo-on signal (SON) does not switch on the base circuit. 15.7.1 Data transfer procedure Each time the servo-on (SON) is turned ON (when the power is switched ON for example), the programmable controller reads the position data (present position) of the servo amplifier.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.7.2 Transfer method The sequence in which the base circuit is turned ON (servo-on) when it is in the OFF state due to the servo-on (SON) going OFF, an emergency stop (EMG), or alarm (ALM), is explained below. In the absolute position detection system, every time the servo-on (SON) is turned on, the ABS transfer mode (ABSM) should always be turned on to read the current position in the servo amplifier to the controller.
15. ABSOLUTE POSITION DETECTION SYSTEM 1) The ready (RD) is turned ON when the ABS transfer mode (ABSM) is turned OFF after transmission of the ABS data. While the ready (RD) is ON, the ABS transfer mode (ABSM) input is not accepted. 2) Even if the servo-on (SON) is turned ON before the ABS transfer mode (ABSM) is turned ON, the base circuit is not turned ON until the ABS transfer mode (ABSM) is turned ON. If a servo alarm has occurred, the ABS transfer mode (ABSM) is not received.

ABSOLUTE POSITION DETECTION SYSTEM (b) Detailed description of absolute position data transfer Servo-on (programmable controller) Servo-on (SON) ON OFF ON OFF (Note) ABS transfer mode (ABSM) ABS request (ABSR) Send data ready (TLC) ON 7) 1) During transfer of ABS OFF 3) ON 5) OFF ON OFF Transmission (ABS) data 2) 4) 6) 1 2 Lower 2 bits 18 19 Checksum Upper 2 bits Note.
15. ABSOLUTE POSITION DETECTION SYSTEM (c) Checksum The checksum is the code which is used by the programmable controller to check for errors in the received ABS data. The 6-bit checksum is transmitted following the 32-bit ABS data. At the programmable controller, calculate the sum of the received ABS data using the ladder program and compare it with the checksum code sent from the servo. The method of calculating the checksum is shown.
15. ABSOLUTE POSITION DETECTION SYSTEM (2) Transmission error (a) Time-out warning(AL.E5) In the ABS transfer mode, the time-out processing shown below is executed at the servo. If a timeout error occurs, an ABS time-out warning (AL.E5) is output. The ABS time-out warning (AL.E5) is cleared when the ABS transfer mode (ABSM) changes from OFF to ON.
15. ABSOLUTE POSITION DETECTION SYSTEM 3) ABS transfer mode finish-time time-out check If the ABS transfer mode (ABSM) is not turned OFF within 5s after the last ready to send signal (19th signal for ABS data transmission) is turned ON, it is regarded as the transmission error and the ABS time-out warning (AL.E5) is output. 5s ON ABS transfer mode OFF ON Signal is not turned OFF 1 2 3 4 18 19 ABS request OFF ON Send data ready 1 OFF 2 3 4 18 19 Yes AL.
15. ABSOLUTE POSITION DETECTION SYSTEM 5) Servo-on (SON) OFF, Reset (RES) ON, Emergency stop (EMG) OFF check during the ABS transfer When the ABS transfer mode is turned ON to start transferring and then the servo-on (SON) is turned OFF, the reset (RES) is turned ON, or the emergency stop (EMG) is turned ON before the 19th send data ready signal is turned ON, the ABS time-out warning (AL.E5) occurs, regarding it as a transfer error.
15. ABSOLUTE POSITION DETECTION SYSTEM (b) Checksum error If the checksum error occurs, the programmable controller should retry transmission of the ABS data. Using the ladder check program of the programmable controller, turn OFF the ABS transfer mode (ABSM). After a lapse of 10ms or more, turn OFF the servo-on (SON) (OFF time should be longer than 20ms) and then turn it ON again.
15. ABSOLUTE POSITION DETECTION SYSTEM (3) At the time of alarm reset If an alarm occurs, turn OFF the servo-on (SON) by detecting the alarm output (ALM). If an alarm has occurred, the ABS transfer mode (ABSM) cannot be accepted. In the reset state, the ABS transfer mode (ABSM) can be input.
15. ABSOLUTE POSITION DETECTION SYSTEM (4) At the time of emergency stop reset (a) If the power is switched ON in the emergency stop state The emergency stop state can be reset while the ABS data is being transferred. If the emergency stop state is reset while the ABS data is transmitted, the base circuit is turned ON 80[ms] after resetting. If the ABS transfer mode (ABSM) is OFF when the base circuit is turned ON, the ready (RD) is turned ON 20[ms] after the turning ON of the base circuit.
15. ABSOLUTE POSITION DETECTION SYSTEM (b) If emergency stop is activated during servo-on The ABS transfer mode (ABSM) is permissible while in the emergency stop state. In this case, the base circuit and the ready (RD) are turned ON after the emergency stop state is reset.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.7.3 Home position setting (1) Dog type home position return Preset a home position return creep speed at which the machine will not be given impact. On detection of a zero pulse, the home position setting (CR) is turned from off to on. At the same time, the servo amplifier clears the droop pulses, comes to a sudden stop, and stores the stop position into the nonvolatile memory as the home position ABS data.
15. ABSOLUTE POSITION DETECTION SYSTEM (2) Data set type home position return POINT Never make home position setting during command operation or servo motor rotation. It may cause home position sift. It is possible to execute data set type home position return when the servo off. Move the machine to the position where the home position is to be set by performing manual operation such as jog operation to turn the motor shaft more than one revolution.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.7.4 Use of servo motor with electromagnetic brake The timing charts at power on/off and servo-on (SON) on/off are given below. Preset " 1 " in parameter No. 1 to make the electromagnetic brake interlock (MBR) usable. When the ABS transfer mode is ON, the electromagnetic brake interlock (MBR) is used as the ABS data bit 1.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.7.5 How to process the absolute position data at detection of stroke end The servo amplifier stops the acceptance of the command pulse when stroke end (LSP LSN) is detected, clears the droop pulses to 0 at the same time, and stops the servo motor rapidly. At this time, the programmable controller keeps outputting the command pulse.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.8 Examples of use 15.8.1 MELSEC-A1S (A1SD71) (1) Instructions The absolute coordinate system (programmable controller coordinate system) of the A1SD71 (AD71) only covers the range in which the address increases (positive coordinate values) on moving away from the machine home position (the position reached in the home position return operation).
15. ABSOLUTE POSITION DETECTION SYSTEM If the address of the machine home position is changed to any coordinate value other than "0", the programmable controller coordinate system will be as illustrated below. The power should be turned ON/OFF in the range in which the address increases on moving away from the home position.
15. ABSOLUTE POSITION DETECTION SYSTEM (d) Slot arrangement The sequence programs presented in this section show I/O numbers (X, Y) assuming the arrangement of modules on the main base unit is as illustrated below. A1SD71 is mounted at I/O slots 0 and 1, a 16-point input module at slot 2, and 16-point output module at slot 3. If the actual arrangement of the modules differs from this arrangement, change the X and Y numbers accordingly. The numbers of the devices (M, D, T, etc.

15. ABSOLUTE POSITION DETECTION SYSTEM (2) ABS communication error (a) The OFF period of the send data ready signal output from the servo amplifier is checked. If the OFF period is 1s or longer, this is regarded as a transfer fault and the ABS communication error is generated. The ABS communication error occurs if the ABS time-out warning (AL.E5) is generated at the servo amplifier due to an ABS request ON time time-out.
15. ABSOLUTE POSITION DETECTION SYSTEM (c) To detect the ABS time-out warning (AL.E5) at the servo amplifier, the time required for the ABS request signal to go OFF after it has been turned ON (ABS request time) is checked. If the ABS request remains ON for longer than 1s, it is regarded that an fault relating to the ABS request signal or the send data ready (TLC) has occurred, and the ABS communication error is generated. The ABS communication error occurs if the ABS time-out warning (AL.
