Over Torque Signal
The inverter outputs the over torque signal when it detects that the estimated motor
output torque exceeds the specified level.
To enable this function, assign “
07
(OTQ)” to an intelligent output terminal.

Over torque signal
ON
when the estimated output torque >
C055
~
C058
OFF
when no over torque is detected
Valid for inputs:
11, 12, AL0 – AL2
Example for terminal [11] (default output
configuration shown – see
page 3-90
):
Example for terminal [AL0], [AL1], [AL2] (requires
output configuration – see
page 4-52 and 3-90
):
See I/O specs on
page 4-6

C058
Notes:
•
This function is effective only when the V/F
characteristic curve selection
A044
is set to “
03
(SLV mode)”. With any other V/F characteristic
curve selection, the output of the OTQ signal is
unpredictable.
•
When using the inverter for a lift, use the OTQ
signal as the trigger to stop braking. Use the
frequency arrival signal as the trigger to start
braking.
•
The example circuit for terminal [11] drives a relay
coil. Note the use of a diode to prevent the
negative-going turn-off spike generated by the coil
from damaging the inverter’s output transistor.
