All = Terminals 18, 19, 27, 29, 32, 33, X30/2, X30/3, X30/4. X30/ are the terminals on MCB 101.
Terminal 29 is available in FC 302 only.
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 converter. Logic
‘0’ => coasting stop and reset.
[4]
Quick stop inverse
Inverted input (NC). Generates a stop in accordance with quick-stop ramp time set in par. 3-81. When motor
stops, the shaft is in free mode. Logic ‘0’ => Quick-stop.
[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 selected 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).
