G7 ASD Operation Manual 157
Overtorque Trip
Program ⇒ Protection Parameters ⇒ Overtorque Parameters
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 overtorque conditions.
Settings:
Disabled
Enabled (box checked)
Direct Access Number — F615
Parameter Type — Check Box
Factory Default — Disabled
Changeable During Run — No
Overtorque Trip/Alarm Level (Positive Torque)
Program ⇒ Protection Parameters ⇒ Overtorque Parameters
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 drive.
Direct Access Number — F616
Parameter Type — Numerical
Factory Default — 150.0
Changeable During Run — No
Minimum — 0.00
Maximum — 250.0
Units — %
Overtorque Trip/Alarm Level (Negative Torque)
Program ⇒ Protection Parameters ⇒ Overtorque Parameters
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 drive.
Direct Access Number — F617
Parameter Type — Numerical
Factory Default — 150.0
Changeable During Run — No
Minimum — 0.00
Maximum — 250.0
Units — %
Overtorque Detection Time
Program ⇒ Protection Parameters ⇒ Overtorque Parameters
This parameter sets the amount of time that the overtorque condition may
exceed the tripping threshold level set at
F616 and F617 before a trip occurs.
Direct Access Number — F618
Parameter Type — Numerical
Factory Default — 0.50
Changeable During Run — No
Minimum — 0.00
Maximum — 100.0
Units — Seconds
Cooling Fan Control
Program ⇒ Protection Parameters ⇒ Cooling Fan Settings
This parameter sets the cooling fan run-time command.
Settings:
Automatic
Always On
Direct Access Number — F620
Parameter Type — Selection List
Factory Default — Automatic
Changeable During Run — Ye s
