Q7 ASD Installation and Operation Manual
Overtorque Trip
Program
⇒
Protection
⇒
Overtorque Trip
This parameter Enables/Disables the Over Torque Tripping function.
When enabled, the ASD trips if an output torque larger than the setting of
parameters Overtorque Trip/Alarm Level (Positive Torque) or Overtorque
Trip/Alarm Level (Positive Torque) is detected for a time longer than the
setting of the Overtorque Detection Time parameter.
When disabled, the ASD does not trip due to overtorque conditions.
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — No
Overtorque Level Negative
Program
⇒
Protection
⇒
OT Level Neg
This parameter sets the torque threshold level that is used as a setpoint for
overtorque tripping during regeneration. This setting is a percentage of the
maximum rated torque of the ASD.
Parameter Type — Numerical
Factory Default — 150.0
Changeable During Run — No
Minimum — 0.00
Maximum — 250.0
Units — %
Overtorque Level Positive
Program
⇒
Protection
⇒
OT Level Pos
This parameter sets the torque threshold level that is used as a setpoint for
overtorque tripping. This setting is a percentage of the maximum rated torque
of the ASD.
Parameter Type — Numerical
Factory Default — 150.0
Changeable During Run — No
Minimum — 0.00
Maximum — 250.0
Units — %
Overvoltage Stall Level (1)
Program
⇒
Protection
⇒
Overvolt Stall
This parameter Enables/Disables the Overvoltage Stall function.
When enabled, this function causes the ASD to extend the decel time when the
DC bus voltage increases due to transient voltage spikes, regeneration, supply
voltage out of specification, etc. in an attempt to reduce the bus voltage.
Settings:
Enabled
Disabled
Enabled (Forced Shorted Deceleration)

Factory Default — Disabled
Changeable During Run — Yes
