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 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 is active when there is a start command or the
output frequency is above 0.1 Hz. Also active during ramp-
down.
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.
Select Reversing to activate the relay output 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 active when [1] Local
operation is selected for parameter 002 Local/remote
operation.
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.
Use Mechanical brake control to control an external
mechanical brake. See chapter 3.4.13 Control of Mechanical
Brake for more details about mechanical brake control.
Control word bit 11 is active if bit 11 is high on the Bus
Communication.
Sleep Mode is active of the frequency is lower than 0.1 Hz.
