Control word bit 11
(CTRL W. BIT 11)
Function:
The relay output can be used for giving the present status or warning.
The output is activated (1–2 make) when a given condition is fulfilled.
Description of choice:
No function . Is selected if the frequency converter is not to react to sig-
nals.
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 receiving 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 .

Relay 123
is only used in connection with Profidrive.
Reversing
, The relay output is activated when the direction of motor ro-
tation 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 active when in parameter 002
operation, Local operation
[1] has been selected.
Out of the frequency range,
the output frequency is out of the program-
med 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).
Control word bit 11, bit 11of the control word, the relay output will be
set/reset according to bit 11.
