Control word bit 11
(CTRL W. BIT 11)
Function:
The relay output can be used for gi v ing the present
status or warning. The output is acti v ated (1–2
make) when a gi v en condition is fulfilled.
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 gi v en. No warning.
Running, a start command has been gi v en.
Running in reference, no warning speed
according to reference.
Running, no warning, a start command has
been gi v en. No warning.
Ready - mains voltage within range, the frequency
converter is ready for use; the control card is
recei v ing a supply voltage; and there are no
acti v e control signals on the inputs. The mains
voltage lies within the voltage limits.
Alarm or warning, the output is acti v ated by
an alarm or warning.
Current limit, the output current is higher than the
value programmed in parameter 221 Current limit I
Alarm, The output is acti v ated by an alarm.
Output frequency higher than f
frequency is higher than the value set in parameter
225 Warning: Low frequency, f
Output frequency lower than f
frequency is lower than the value set in parameter
226 Warning: High frequency, f
Output current higher than I
current is higher than the value set in parameter
223 Warning: Low current, I
Output current lower than I
is lower than the value set in parameter 224
Warning: High current, I

Feedback higher than FB
is higher than the value set in parameter 227

Relay 123 is only used in connection with Profidri v e.
Reversing, The relay output is acti v ated when
the direction of motor rotation is anti-clockwise.
When the direction of motor rotation is clockwise,
the value is 0 V DC.
Thermal warning, above the temperature limit in
either the motor or the frequency converter, or from
a thermistor connected to a digital input.
Local operation, the output is acti v e when in
parameter 002 Local/remote operation, Local
operation [1] has been selected.
Out of the frequency range, the output frequency
is out of the programmed frequency range in
parameters 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).
