(b) Turn the external input (TREN signal) on after turning the clutch ON/OFF
command device on.
In this mode, a time for maximum 2 operation cycles is required to turn the
external input on after the clutch ON/OFF command device turns on.
1) If the external input turns from off to on when the clutch ON/OFF
command device is OFF, the clutch is not set to the ON state.
2) If the clutch ON/OFF device turns on when the external input is ON, the
clutch is not set to the ON state.
3) If the external input turns off after the clutch is set to the ON state, the
clutch state remain ON.
(c) The clutch status signal ON/OFF is refreshed by the operation cycle.
(d) The current value of input axis (synchronous encoder) changes at the clutch
ON state only.

(e) Only axis that the incremental synchronous encoder (manual pulse
generator) is set as drive module can be used in this mode. When an
absolute synchronous encoder is set as the drive module, it cannot be used.
