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 con-
verter 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 con-
verter is ready for use; the control card is receiving a
supply voltage; and there are no active control signals

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
V DC.
Thermal warning, above the temperature limit in either
the motor or the frequency converter, or from a ther-
mistor connected to a digital input.
Local operation, the output is active 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).
