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 and coasting stop Inverted input (NC).
reset inverse Leaves motor in free mode and resets the
frequency converter. Logic '0'⇒coasting stop
and reset.
[5] DC-brake Inverted input for DC braking (NC).
inverse Stops motor by energising it with a DC
current for a certain time period. See
parameter 2-01 DC Brake Current to
parameter 2-03 DC Brake Cut In Speed [RPM].
The function is only active when the value
in parameter 2-02 DC Braking Time is
different from 0. Logic '0' ⇒DC braking.
This selection is not possible when
parameter 1-10 Motor Construction is set to
[1] PM, non salient SPM.
[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 (parameter 3-42 Ramp 1 Ramp Down
Time and parameter 3-52 Ramp 2 Ramp
Down Time.
NOTICE
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 [27] Torque limit & stop and
connect this digital output to a digital
input that is configured as coast.
[7] External Same function as Coasting stop, inverse, but
Interlock External Interlock generates the alarm
message 'external fault' in the display when
the terminal which is programmed for Coast
Inverse is logic '0'. The alarm message is also
active via digital outputs and relay outputs,
if programmed for External Interlock. The
alarm can be reset using a digital input or
the [Reset] key if the cause for the External
Interlock has been removed. A delay can be
programmed in parameter 22-00 External
Interlock Delay. After applying a signal to the
