All = Terminals 18, 19, 27, 29, 32, X30/2, X30/3, X30/4. X30/ are the terminals on MCB 101.
Functions dedicated to only one digital input are stated in the associated parameter.
All digital inputs can be programmed to these functions:
[0] No operation No reaction to signals transmitted to terminal.
[1] Reset Resets frequency converter after a TRIP/ALARM. Not all alarms
can be reset.
[2] Coast inverse Leaves motor in free mode. Logic ‘0’ => coasting stop.
(Default Digital input 27): Coasting stop, inverted input (NC).
[3] Coast and reset in-
verse
Reset and coasting stop Inverted input (NC).
Leaves motor in free mode and resets the frequency converter.
Logic ‘0’ => coasting stop and reset.
[5] DC-brake inverse Inverted input for DC braking (NC).
Stops motor by energizing it with a DC current for a certain time
period. See par. 2-01 to par. 2-03. The function is only active
when the value in par. 2-02 is different from 0. Logic ’0’ => DC
braking.
[6] Stop inverse Stop Inverted function. Generates a stop function when the se-
lected terminal goes from logical level ‘1’ to ‘0’. The stop is
performed according to the selected ramp time (par. 3-42, par.
3-52, par. 3-62, par. 3-72).
