Q9 ASD Installation and Operation Manual 133
Over-Torque Trip
Program

Protection
This parameter Enables/Disables the Over-Torque Tripping function.
When enabled, the ASD trips if an output torque value greater than the setting of
F616 or F617 exists for a time longer than the setting of F618 .
When disabled, the ASD does not trip due to over-torque conditions.
Note: A discrete output terminal may be activated when an over-torque
alarm occurs if so configured (see
F130 ).
Settings:
0 — Disabled
1 — Enabled
Direct Access Number — F615
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — No
Over-Torque Level (Positive Torque)
Program

Protection
This parameter sets the torque threshold level that is used as a setpoint for over-
torque tripping during positive torque. This setting is a percentage of the
maximum rated torque of the drive.
This function is enabled at F615 .
Direct Access Number — F616
Parameter Type — Numerical
Factory Default — 250.00
Changeable During Run — No
Minimum — 0.00
Maximum — 250.00
Units — %
Over-Torque Detection Level (Negative Torque)
Program

Protection
This parameter sets the torque threshold level that is used as a setpoint for over-
torque tripping during negative torque (Regen). This setting is a percentage of the
maximum rated torque of the drive.
This function is enabled at F615 .
Direct Access Number — F617
Parameter Type — Numerical
Factory Default — 250.00
Changeable During Run — No
Minimum — 0.00
Maximum — 250.00
Units — %
Over-Torque Detection Time
Program

Protection
This parameter sets the amount of time that the over-torque condition may exceed
the tripping threshold level set at
F616 and F617 before a trip occurs.
This function is enabled at F615 .
Direct Access Number — F618
Parameter Type — Numerical
Factory Default — 0.50
Changeable During Run — No
Minimum — 0.00
Maximum — 10.0
Units — Seconds
Over-Torque Detection Hysteresis
Program

Protection
During a momentary over-torque condition, this parameter provides a torque
threshold level to which the over-torque condition must return within the time
setting of
F618 or an Over-Torque Trip will be incurred.
Direct Access Number — F619
Parameter Type — Numerical
Factory Default — 10.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — 100.00
