6.16.9 Over-torque trip
 : Over-torque trip/alarm selection
 : Over-torque detection level
 : Over-torque detection time
 : Over-torque detection hysteresis
 Function
If the torque value exceeds the value set at  and doesn’t return below -
for a time that exceeds the value set at , tripping or output alarm will be activated.
 is displayed in the event of a trip.
=: .......... No tripping (FL relay deactivated).
An over-torque alarm can be put out by setting the output terminal function selection
parameter.
=: .......... The inverter is tripped (FL relay activated) only after a torque exceeding the -
specified level has been detected for more than the -specified time.
