VLT Automation Low Harmonic Drive Operating Instructions
Output speed is lower than the setting in
4-52 Warning Speed Low.
Output speed is higher than the setting
in 4-53 Warning Speed High.
Feedback is outside the range set in
4-56 Warning Feedback Low and
4-57 Warning Feedback High.
Feedback is below the limit set in
4-56 Warning Feedback Low.
Feedback is above the limit set in
4-57 Warning Feedback High.
The thermal warning turns on when the
temperature exceeds the limit in the
motor, the frequency converter, the brake
resistor, or the thermistor.
The frequency converter is ready for
operation and there is no over-
temperature warning.
The frequency converter is ready for
operation and is in [Auto on] mode.
There is no over-temperature warning.
The frequency converter is ready for
operation and the mains voltage is within
the specified voltage range (see General
Specifications section in the Design
Guide).
Reversing. Logic '1' when CW rotation of
the motor. Logic '0' when CCW rotation
of the motor. If the motor is not rotating
the output will follow the reference.
Active communication (no time-out) via
the serial communication port.
Use in performing a coasting stop and in
torque limit condition. If the frequency
converter has received a stop signal and
is at the torque limit, the signal is Logic
'0'.
Brake is active and there are no warnings.
Brake is ready for operation and there are
no faults.
Output is Logic '1' when the brake IGBT is
short-circuited. Use this function to
protect the frequency converter if there is
a fault on the brake modules. Use the
output/relay to cut out the main voltage
from the frequency converter.
Relay is activated when Control Word [0]
is selected in parameter group 8-**.
Enables control of an external mechanical
brake, see description in the section
Control of Mechanical Brake, and
parameter group 2-2*
Indicates that the safe stop on terminal
37 has been activated.

Controls output via bus. The state of the
output is set in 5-90 Digital & Relay Bus
Control. The output state is retained in
the event of bus time-out.
Controls output via bus. The state of the

See parameter group 13-1*. If Comparator
0 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
See parameter group 13-1*. If Comparator
1 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
See parameter group 13-1*. If Comparator
2 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
See parameter group 13-1*. If Comparator
3 is evaluated as TRUE, the output will go
