FCD Series
Description of choice:
No function. Is selected if the frequency converter is
not to react to signals.
Unit ready, there is a supply voltage on the control
card of the frequency converter, and the frequency
converter is ready for operation.
Enable, no warning, the frequency converter is ready
for operation, but no start command has been given.
No warning.
Running, a start command has been given.
Running in reference, no warning speed according
to reference.
Running, no warning, a start command has been
given. No warning.
Ready - mains voltage within range, the frequency
converter is ready for use; the control card is receiv-
ing a supply voltage; and there are no active control
signals on the inputs. The mains voltage lies within
the voltage limits.
Alarm or warning, the output is activated by an
alarm or warning.
Current limit, the output current is higher than the
value programmed in parameter 221 Current limit
I
LIM
.
Alarm, The output is activated by an alarm.
Output frequency higher than f

, the output fre-
quency is higher than the value set in parameter 225
Warning: Low frequency, f

Relay 123 is only used in connection with Profidrive.
Reversing, The relay output is activated when the di-
rection of motor rotation is anti-clockwise. When the
direction of motor rotation is clockwise, the value is 0
VDC.
Thermal warning, above the temperature limit in ei-
ther the motor or the frequency converter, or from a
thermistor connected to a digital input.
Local operation, the output is active when in param-
eter 002 Local/remote operation, Local operation [1]
has been selected.
Pulse output can only be selected in par. 341 Digital
output terminal 46.
Out of the frequency range, the output frequency is
out of the programmed frequency range in parame-
ters 225 and 226.
Out of the current range, the motor current is out of
the programmed range in parameters 223 and 224.
Out of the feedback range, the feedback signal is out
of the programmed range in parameters 227 and
228.
Mechanical brake control, enables you to control an
external mechanical brake (see section about control
of mechanical brake in the Design Guide).
