Clearing of Position
The current position is cleared to zero by digital input "PCLR" turning ON. The current position can be
cleared to zero in either position control and speed control. Either of the ON edge and ON level can be
selected as the timing to clear the current position.
When "PCLR" is turned ON during position control operation, the current position is cleared to zero
and movement to the target position is performed. When "PCLR" is turned ON after position control
stop, the current position is cleared to zero, however, movement to the target position is not started. To
perform movement, either turn the RUN command OFF then back ON again, or turn "POS-SET" ON.
