Clutch - Mitsubishi Electric MELSERVO-J4 Series Instruction Manual

12. APPLICATION OF FUNCTIONS

12.1.14 Clutch

The clutch is used to transmit/disengage command pulses from the main shaft input side to the output axis
module through turning the clutch ON/OFF, controlling start/stop of the servo motor operation.
Set whether or not to use the clutch control with [Cam control data No. 36 - Main shaft clutch control setting].
Although the clutch ON/OFF can be changed during cam control, the setting of [Cam control data No. 36]
cannot be changed from "1 (Clutch command ON/OFF)" to "0 (No clutch)" during cam control.
When the clutch ON condition and the clutch OFF condition are simultaneously established within the DI
scan cycle, both clutch ON processing and clutch OFF processing are executed within the DI scan cycle.
Therefore, the clutch status changes from OFF to ON and OFF again when the conditions are established in
the clutch OFF status, and the status changes from ON to OFF and ON again when the conditions are
established in the clutch ON status.
POINT
Use C_CLTC (Clutch command (bit 11 of 2D02h)) to input a clutch command
via the Modbus-RTU communication.
Use S_CLTS (Clutch on/off status (bit 11 of 2D12h)) to read the output status of
the clutch on/off status.
Use S_CLTSM (Clutch smoothing status (bit 12 of 2D12h)) to read the output
status of the clutch smoothing status via the Modbus-RTU communication.
C_CLTC, S_CLTS, and S_CLTSM are available with servo amplifiers with
software version C1 or later. For details, refer to "MR-J4-_A_-RJ Servo Amplifier
Instruction Manual (Modbus-RTU communication)".
