Function Display
Digital outputs can be assigned one of 6 different signalling functions. Both outputs may also be assigned to the
same function. The oututs can be programmed either as normally closed contacts or as normally open contacts.

Programmable digital outputs
One of the following signalling functions can be assigned:
00: RUN signal (signal active during motor run)
01: FA1 signal (frequency arrival)
N 02: FA2 signal (frequency exceeded)
03: OL signal (overload)
04: OD signal (PID-deviation exceeded)
05: AL signal (alarm signal)
N Refer to C 21 for possible parameters
The FM output terminal can be used to output one of the following
values:
00: Output frequency display (analog signal 0–10VDC)
N
01: Motor current display (analog signal 0–10VDC;
100% of the rated current corresponds to 5VDC)
02: Output frequency (digital pulse signal)
N 00: Normally open contact
N Refer to C 31 for possible parameters

01: Normally closed contact
If digital output terminals 11
C 41
or 12 have been configured for
output of the overload signal
then the current value entered
here determines when the over-
load signal will be activated.
The digital output terminal 11 or
12 configured as FA2 will be
C 43
activated when the frequency
entered here is exceeded during
acceleration.
(Setting range: 0Hz–360Hz)
The digital output terminal 11 or 12
configured as OD will be activated
C 44
when the difference between the set
C 44
value and actual value exceeds the
value entered here (when PID control
is activated). (Setting range: 0–100%
of the maximum set value).
