Home Position Return In The Bcd (3 Digits × 2) Input Operation - Mitsubishi Electric MELSERVO-J4 Series Instruction Manual

11. MR-D01 EXTENSION I/O UNIT
(4) Temporary stop/restart during automatic operation
When TSTP (Temporary stop/restart) is switched on during automatic operation, the servo motor
decelerates with the deceleration time constant of the point table being executed, and then stops
temporarily. Switching on TSTP (Temporary stop/restart) again starts the servo motor rotation for the
remaining travel distance.
During a temporary stop, ST1 (Forward rotation start) or ST2 (Reverse rotation start) does not function
even if it is switched on.
Changing the automatic mode to manual mode during a temporary stop will erase a travel remaining
distance.
The TSTP (Temporary stop/restart) does not function during a home position return or JOG operation.
11.7.4 Home position return in the BCD (3 digits × 2) input operation
The home position return in the BCD (3 digits × 2) input operation is the same as the one in the point table
method. Refer to section 4.4. For the devices, refer to the following table.
