Feedback higher than FB
LOW
, the feedback value
is higher than the value set in parameter 227
Warning: Low feedback, FB
LOW
.
Feedback lower than FB
HIGH
, the feedback value
is lower than the value set in parameter 228
Warning: High current, I
HIGH
.
Relay 123
is only used in connection with Profidrive.
Reversing
, The relay output is activated 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 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).

Function:
The digital output can be used for giving the present
status or warning. The digital output (terminal 46) gives
a 24 V DC signal when a given condition is fulfilled.
Terminal can also be used for frequency output.
Parameter 342 sets the maximum pulse frequency.
Description of choice:
Pulse reference Ref
MIN
- Ref

MAX
(parameters 204/205).
Pulse feedback FB
MIN
-FB
MAX
.
An output signal is obtained, which is proportional to the
feedback value in the interval Minimum feedback, FB
MIN
- Maximum feedback, FB
MAX
(parameter 414/415).
Output frequency 0-f
MAX
.
An output signal is obtained, which is proportional to
the output frequency in the interval 0 - f
MAX
(parameter
202
Output frequency, high limit, f
