2) When the clutch ON/OFF command device is OFF and the current value
of virtual axis reaches an address set in the clutch OFF address setting

(b) The clutch ON/OFF control differs according to the output module connected
as follows.
1) For a ball screw or roller
The ON/OFF control is executed by the current value of virtual axis.
When a differential gear is connected to the main shaft, the ON/OFF
control is executed by the current value after the main shaft's differential
gear.
2) For a rotary table or cam
The ON/OFF control is executed by the current value within 1 virtual axis
