■Address mode
The clutch is turned OFF when the reference address reaches "Clutch OFF address".
The movement amount before passing through the OFF address is calculated as the output movement amount of the clutch
based on the reference address passing through, thereby controlling the clutch with an accurate movement amount.
■High speed input request
The clutch is turned OFF when the high speed input request [DI] turns ON.
The following actions are required when using the high speed input request.
• Set the signal No. for the "High speed input request signal" clutch control setting.
