Table 6.5 Digital Input Functions
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 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
3-81 Quick Stop Ramp Time. When motor stops,
