9.5.5 Phase Specification Clutch OFF Function

What is phase specification clutch OFF function?
•
The "phase specification clutch OFF function" is a function for disconnecting an electronic
clutch (OFF) at an arbitrarily specified phase. For stopping or starting at the same phase
repeatedly, the control without variance can be performed. This function is available since
FP7 MC Unit Ver. 1.20.
•
However, select "Direct" for the clutch OFF method. When selecting "Slip", variation in stop
position is caused because it stops after the elapse of a slip time from a stop phase
arbitrarily set.

Clutch OFF method (Direct)
When performing the OFF request by the I/O signal, the clutch off operation will be executed
regardless of phase.
