PTC Card 1
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 No reaction to signals transmitted to the
operation terminal.
[1] Reset Resets frequency converter after a TRIP/ALARM.
Not all alarms can be reset.
[2] Coast (Default Digital input 27): Coasting stop,
inverse inverted input (NC). The frequency converter
leaves the motor in free mode. Logic '0' =>
coasting stop.
[3] Coast and Reset and coasting stop Inverted input (NC).
reset Leaves motor in free mode and resets frequen-
inverse cy converter. Logic '0' => coasting stop and
reset.
[4] Quick stop Inverted input (NC). Generates a stop in accord-
inverse ance with quick-stop ramp time set in
par. 3-81 Quick Stop Ramp Time. When motor
stops, the shaft is in free mode. Logic '0' =>
Quick-stop.
[5] DC-brake Inverted input for DC braking (NC). Stops motor
inverse by energizing it with a DC current for a certain
time period. See par. 2-01 DC Brake Current to
par. 2-03 DC Brake Cut In Speed [RPM]. The
function is only active when the value in
par. 2-02 DC Braking Time 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 Ramp 1 Ramp Down Time,
par. 3-52 Ramp 2 Ramp down Time,
par. 3-62 Ramp 3 Ramp down Time,
par. 3-72 Ramp 4 Ramp Down Time).
NOTE
When the frequency converter is at
the torque limit and has received a
stop command, it may not stop by
itself. To ensure that the frequency
converter stops, configure a digital
output to Torque limit & stop [27] and
connect this digital output to a digital
input that is configured as coast.
