Set the command disable the
clutch control temporarily.
Set the command to force the
clutch OFF.
(1) [Rq.400] Main shaft clutch command (M11680+10n)
Use ON/OFF for the main shaft clutch command. This command is used with the
following settings.
• The clutch ON control mode is "1: Clutch command ON/OFF", "2: Clutch
command leading edge" or "3: Clutch command trailing edge".
• The clutch OFF control mode is either "2: Clutch command leading edge" or "3:
Clutch command trailing edge".
Status is considered as clutch command OFF just before starting synchronous
control. If synchronous control is started while the clutch command is ON, the
condition is established just after starting synchronous control, by setting "2:
Clutch command leading edge". The condition is not established just after
starting, by setting "3: Clutch command trailing edge".
(2) [Rq.401] Main shaft clutch control invalid command (M11681+10n)
The main shaft clutch control is invalid if ON is set. The previous clutch ON/OFF
status remains before clutch control becomes invalid.
Clutch control will not become invalid during movement by [Pr.408] and [Pr.410]
before clutch ON and clutch OFF. Instead, clutch control will become invalid after
movement is completed.
(3) [Rq.402] Main shaft clutch forced OFF command (M11682+10n)
Set ON to force the clutch OFF. The output value from the clutch becomes 0
immediately, even during clutch smoothing. The slippage (accumulative) amount
is set to 0 if smoothing with a slippage method.
Reset to OFF to restart the clutch control from the clutch OFF status after using
the clutch forced OFF command.
