G7 ASD Operation Manual 157
Overtorque Trip
Program ⇒ Protection Parameters ⇒ Overtorque Parameter s
This parameter Enables/Disables the Over Torque Tripping function.
When enabled, the ASD trips if an output torque value greate r th an th e se tt ing
of F616 or F617 exists for a time longer than the setting of F618.
When disabled, the ASD does not trip due to overtorque conditions.
Settings:
Disabled
Enabled (box checked)
Direct Access Number — F615

Overtorque Trip/Alarm Level (Negative Torque)
Program ⇒ Protection Parameters ⇒ Overtorque Parameter s
This parameter sets th e torque threshold lev el that is used as a setpoint for
overtorque tripping during regenerat ion. This setting is a percentage of the
maximum rated torque of the drive.
