Functions dedicated to only 1 digital input are stated in the associated parameter.
All digital inputs can be programmed to these functions:
Table 283: Digital Inputs, Function Descriptions - 1
Option Function
[0] No operation No reaction to signals transmitted to the terminal.
[1] Reset Resets the drive after a trip/alarm. Not all alarms can be reset.
[2] Coast inverse (Default digital input 27): Coast stop, inverted input (NC). The drive leaves the motor in free mode. Logic
0⇒coast stop.
[3] Coast and re- Reset and coast stop inverted input (NC). Leaves the motor in free mode and resets the drive. Logic
set inverse 0⇒coast stop and reset.

Quick Stop Ramp Time. When the motor stops, the shaft is in free mode. Logic 0⇒quick stop.
[5] DC brake in- Inverted input for DC brake (NC). Stops motor by energizing it with a DC current for a certain time peri-
verse od. See parameter 2-01 DC Brake Current to parameter 2-03 DC Brake Cut In Speed [RPM]. The function is
only active when the value in parameter 2-02 DC Braking Time is different from 0. Logic 0⇒DC brake.
[6] Stop inverse
Stop inverted function. Generates a stop function when the selected terminal goes from logical level 1 to
