01 Stop Coast Three wire stop. However, it functions as a stop under all input modes and cannot be disabled. P045
02 DigIn TermBlk 02/
Start/Run FWD
Run FWD Used to initiate motion and also can be used as a programmable digital input. It can be programmed with t062 [DigIn
TermBlk 02] as three wire (Start/Dir with Stop) or two wire (Run FWD/Run REV) control. Current consumption is 6 mA.
