The changes do not take effect until the power is supplied again. * That is the end for parameter setting.
7.3 Controller modes After retuning to origin position Before retuning to origin position Controller modes are divided into two types, auto mode and manual mode. There are several status types in one mode. The figure below shows how the status changes. Supply power Auto mode Manual mode A Switching of mode SW Waiting condition Jog / inching Waiting condition Setting of position, speed and acceleration Waiting condition Waiting condition B Positioning or pushing operation by PLC.
(A) Before returning to origin position The transition of the status before returning to origin is shown below. After turning on the power supply, the controller status is in waiting mode which is set by mode switch○ e . The operation of jog / inching at manual mode is available before retuning to origin.
(B) Auto mode after return to origin position The status of the auto mode after return to origin position is shown below. At auto mode, only the operation command such as I/O from PLC is accepted. Basically, position, operation method, speed and acceleration cannot be adjusted in auto mode. Before returning to origin position Waiting Stops at set position After returning to origin position PLC commands Operation PLC to actuate completed commands to Positioning or return to origin. pushing operation.
(C) Manual mode after retuning to origin position The status of the manual mode after return to origin position is shown below. In manual mode, return to origin is controlled by the operation of the controller buttons and switches. The speed and acceleration can be adjusted any time. It is also possible to set the position and operation method. Pushing operation is available during test function.
7.4 Test function The table below shows the difference between normal operation and test function in manual mode. To start the test function, set the position switch ○ h to "0" while the power LED ○ a is on (= servo ON) in manual mode and the actuator stops, and press the set button ○ g for 3sec. When test function starts, the dot on the lower right of the 7-segment LED ○ f will light up.
8. Operations 8.1 Returning to origin position When the power is supplied, it is necessary to return to origin for positioning or pushing of the actuator. (To ensure the position of origin) ■Input of the return to origin position There are 2 ways for returning to origin per mode, Manual mode : Set the position switch○ h at "15" and press the set button○ g . Auto mode : Turn on I/O IN0 to IN3 simultaneously.
8.2 Positioning The actuator travels to the target position at speed and acceleration which are set per operating direction. Operation complete signal is output when the actuator reaches the positioning range of the target position. Ex. Positioning Speed Positioning range Set speed Position Motor Load Actuator M Stop position Target position *The speed wave in the chart above is simplified. 8.
(2) Unsuccessful pushing operation (Idling) If pushing is not completed when the actautor moves from the start position until the actuator's end, it is pushed back at the actuator end and the completion signal is generated. Speed Set speed Pushing speed Position Pushing thrust Load Motor * The velocity wave form in the chart on the left is simplified.
8.4 Jog / inching operation Jog / inching is available by pressing forward button i ○ or reverse button j ○ at manual mode. Jog / inching can be performed before retuning to origin. Operation method Inching starts and stops by pressing forward button i ○ or reverse button j . If you keep pressing ○ the button for 1sec. or longer after inching, jog operation starts. Jog operation stops when the button is released.
8.5 Servo ON Servo ON signal is not assigned to the parallel I/O of this controller.

Any damage attributed to the use beyond the specifications is not guaranteed. 2. There is a possibility of dangerous sudden action by the product if sliding parts of machinery are twisted due to external forces, etc.
4. Refer to a common auto switch /matter (Best Pneumatics No. 2) when an auto switch is built in and used. 5. Return to origin cannot return while operating. It cannot be done during positioning operation, pushing operation and pushing. 14.2 Mounting Warning 1. 2. 3. 4. 5. 6. 7. 8. Install and operate the product only after reading the Operation Manual carefully and understanding its contents. Keep the manual in a safe place future reference. Observe the tightening torque for screws.
3. 4. 5. 6. 1. 2. 3. 4. 5. 6. 7. Immediately stop operation if abnormal operation noise or vibration occurs. If abnormal operation noise or vibration occurs, the product may have been mounted incorrectly. Unless operation of the product is stopped for inspection, the product can be seriously damaged. Never touch the rotating part of the motor or moving part of the actuator while in operation.
14.4 1. 2. 3. 4. 5. 6. Operating environment Warning Avoid use in the following environments. a. Locations where a large amount of dusts and cutting chips are airborne. b. Locations where the ambient temperature is outside the range of the temperature specification (refer to specifications). c. Locations where the ambient humidity is outside the range of the humidity specification (refer to specifications). d. Locations where corrosive gas, flammable gas, sea water, water and steam are present. e.
Caution 1. Maintenance should be performed according to the procedure indicated in the Operating Manual. Incorrect handling can cause injury, damage or malfunction of equipment and machinery. 2. Removal of product. When equipment is serviced, first confirm that measures are in place to prevent dropping of work pieces and run-away of equipment, etc, and then cut the power supply to the system. When machinery is restarted, check that operation is normal with actuators in the proper positions.
15. Controller and its peripheral devices / Specific product precautions 15.1 Design and selection Warning 1. 2. 3. 4. 5. Be sure to apply the specified voltage. Otherwise, a malfunction and breakage of the controller may be caused.

applied to the product. It will cause failure of the controller or its peripheral devices. 13. Do not use the product in an environment subject to a temperature cycle. It will cause failure of the controller or its peripheral devices. 14. Do not use in a place where surges are generated. When there are units that generate a large amount of surge around the product (e.g., solenoid type lifters, high frequency induction furnaces, motors, etc.
15.5 Power supply Caution 1. 2. 3. Use a power supply that has low noise between lines and between power and ground. In cases where noise is high, an isolation transformer should be used. The power supplys should be separated between the controller power and the I/O signal power and both of them do not use the power supply of “rush-current restraining type”. If the power supply is “rush-current restraining type”, a voltage drop may be caused during the acceleration of the actuator.
