FC 300 standard terminals are 18, 19, 27, 29, 32 and 33. MCB 101 terminals are X30/2, X30/3 and X30/4.
Terminal 29 functions as an output only in FC 302.
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 the terminal.
[1] Reset Resets frequency converter after a TRIP/ALARM. Not all alarms can be reset.
[2] Coast inverse (Default Digital input 27): Coasting stop, inverted input (NC). The frequency converter leaves the
motor in free mode. Logic ‘0’ => coasting stop.
[3] Coast and reset inverse Reset and coasting stop Inverted input (NC). Leaves motor in free mode and resets frequency con-
verter. Logic ‘0’ => coasting stop and reset.
