0 = Forward Run Command : Defines a digital input as a forward run command in 2-Wire or 3-Wire control.
For both 2-Wire and 3-Wire control, P38 - Drive Mode should be set to a 1 for normal operation.
For 3-Wire control an additional terminal must be defined as 17 = 3-Wire operation.
1 = Reverse Run Command : Defines a digital input as a reverse run command in 2-Wire or 3-Wire control.
For both 2-Wire and 3-Wire control, P38 - Drive Mode should be set to a 1 for normal operation.
For 3-Wire control an additional terminal must be defined as 17 = 3-Wire operation.
2 = Output Inhibit : Defines a digital input as a drive Output Inhibit. As soon as this input is closed, the drive
output is instantly turned off and the motor will free wheel (coast to a rest). As soon as the input is opened,
the drive will resume previous operation (if in run, the drive will immediately accelerate to the set speed).
While the input is closed the drive display will show ESt [Instant Cut Off].
3 = Fault Reset : Active input resets the fault and resets the drive.
4 = Jog : When active, the drive ramps to the value set in Jog Frequency (F20).
Jog operation overrides all other operations except Dwell operation. If Jog Speed Command is entered
during a Preset Speed, Up-Down or 2-Wire control; operation is executed at Jog frequency, see Figure
7‐4. A valid start command is required separate from the dedicated jog input.
The jog function is only available for 2-Wire control.
