(m) The setting travel value before clutch ON/setting travel value after clutch ON
differs according to the output module connected as follows.
1) For a ball screw or roller
The clutch ON/OFF control is executed by the current travel value of
virtual axis connected.
When a differential gear is connected to the main shaft, the clutch
ON/OFF control is executed by the current travel value after the main
shaft's differential gear.
2) For a rotary table or cam
The clutch ON/OFF control is executed by the travel value of current
value within 1 virtual axis revolution. The setting travel value can be set
outside the range of current value within 1 virtual axis revolution.
(n) When the travel direction set in the setting travel value before clutch ON/
setting travel value after clutch ON does not match the virtual axis or current
value within 1 virtual axis revolution, note that the clutch will turn on/off even
if the condition is not satisfied when the data found by subtracting the travel
value from the specified travel value comes out of the range -2147483648 to
2147483647 [PLS] and changes from
