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.
PAGE 148
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 7.2.3 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.
PAGE 151
7. GENERAL GAIN ADJUSTMENT 7.2.4 Response level setting in auto tuning mode Set the response of the whole servo system in the first digit (response level setting) of parameter No. 2. As the response level setting is increased, the trackability 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 vibration-free range.
PAGE 152
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 PG1 (position control gain 1), VG2 (speed control gain 2) and VIC (speed integral compensation) automatically sets the other gains to the optimum values according to these gains.
PAGE 153
7. GENERAL GAIN ADJUSTMENT (c)Adjustment description 1) Speed control gain 2 (VG2: 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.
PAGE 154
7. GENERAL GAIN ADJUSTMENT (c) Adjustment description 1) Position control gain 1 (PG1: parameter No. 6) This parameter determines the response level of the position control loop. Increasing PG1 improves trackability to a position command but a too high value will make overshooting liable to occur at the time of settling. PG1 guideline VG2 setting (1 load inertia moment ratio) ( 13 to 15 ) 2) Speed control gain 2 (VG2: parameter No.
PAGE 155
7. GENERAL GAIN ADJUSTMENT 7.4 Interpolation mode The interpolation mode is used to match the position control gains of the axes when performing the interpolation operation of servo motors of two or more axes for an X-Y table or the like. In this mode, the model control gains (PG1, VG1) which determine command trackability are set manually and the other gains are set automatically. (1) Parameter PG1 and VG1 can be set manually but the following parameters are automatically adjusted by auto tuning.

PAGE 159
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 Frequency Notch depth Frequency Parameter No. 58 Parameter No.
PAGE 160
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 servo configuration software.

8. SPECIAL ADJUSTMENT FUNCTIONS 8.3 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. 8.3.1 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.

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.
PAGE 227
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) Communication baudrate Choose the communication speed. Match this value to the communication speed of the sending end (master station). Parameter No.
PAGE 228
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 or group to the command, data No., etc. to determine the destination servo amplifier of data communication.

PAGE 231
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.
PAGE 232
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.
PAGE 233
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 15.7 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 SON signal is turned ON (when the power is switched ON for example), the programmable controller reads the position data (present position) of the servo amplifier.
PAGE 259
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) signal going OFF, an emergency stop, or alarm, is explained below. In the absolute position detection system, every time the servo-on (SON) signal is turned on, the ABS transfer mode (ABSM) signal should always be turned on to read the current position in the servo amplifier to the controller.
PAGE 260
15. ABSOLUTE POSITION DETECTION SYSTEM 1) The ready signal (RD) is turned ON when the ABS transfer mode signal (ABSM) is turned OFF after transmission of the ABS data. While the ready signal (RD) is ON, the ABS transfer mode signal (ABSM) input is not accepted. 2) Even if the servo-on (SON) signal is turned ON before the ABS transfer mode signal (ABSM) is turned ON, the base circuit is not turned ON until the ABS transfer mode signal (ABSM) is turned ON.

15. ABSOLUTE POSITION DETECTION SYSTEM (c) Checksum The check sum is the code which is used by the programmable controller to check for errors in the received ABS data. The 6-bit check sum 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 check sum code sent from the servo. The method of calculating the check sum is shown.
PAGE 263
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.
PAGE 264
15. ABSOLUTE POSITION DETECTION SYSTEM 3) ABS transfer mode finish-time time-out check If the ABS transfer mode signal 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 Signal is not turned OFF 1 ON 2 3 4 18 19 ABS request OFF ON Send data ready 1 OFF 2 3 4 18 19 Yes AL.
PAGE 265
15. ABSOLUTE POSITION DETECTION SYSTEM (3) At the time of alarm reset If an alarm occurs, turn OFF the servo-on (SON) signal by detecting the alarm output (ALM). If an alarm has occurred, the ABS transfer mode signal (ABSM) cannot be accepted. In the reset state, the ABS transfer mode signal (ABSM) can be input.
PAGE 266
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 signal (ABSM) is OFF when the base circuit is turned ON, the ready signal (RD) is turned ON 20[ms] after the turning ON of the base circuit.
PAGE 267
15. ABSOLUTE POSITION DETECTION SYSTEM (b) If emergency stop is activated during servo-on The ABS transfer mode signal (ABSM) is permissible while in the emergency stop state. In this case, the base circuit and the ready signal (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 signal (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 non-volatile memory as the home position ABS data.

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 (2) Sequence program example (a) Conditions 1) When the servo-on signal and power supply GND are shorted, the ABS data is transmitted at power-on of the servo amplifier or on the leading edge of the RUN signal after a PC reset operation (PC-RESET). The ABS data is also transmitted when an alarm is reset or when an emergency stop is reset. 2) If a checksum mismatch is detected in the transmitted data, data transmission is retried up to three times.

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 signal has occurred, and the ABS communication error is generated. The ABS communication error occurs if the ABS time-out warning (AL.
