Factory Setting: 0.1

VFD-F Series

This parameter selects the Over-torque Detection operation.

If this parameter is set to 01 or 02, over-torque detection will not occur during acceleration.

06 - 04	Over-torque Detection Level		Factory Setting: 110
	Settings	30~150%	Unit: 1

This parameter sets the Over-torque Detection level based on the AC drive rated current.

06 - 05 Over-torque Detection Time

Settings 0.1~60.0 SecUnit: 0.1 This parameter selects the allowable time of Over-torque Detection before the AC drive faults with an OL2.

When the output current exceeds Pr.06-04 for the time set in Pr06-05, AC drive will fault and display “OL2” on the keypad.

06 - 06 Electronic Thermal Relay Selection

Settings	00:	Operation disabled.
	01:	Operation with a standard motor (shaft mounted fan cooled).

02:Operation with a vector motor (non-fan cooled or self powered fan) This parameter provides electronic thermal protection for the motor. When the output current exceeds Pr.07-02 for the time set in Pr.06-07, the drive will fault with an OL1.

06 - 07 Electronic Thermal Characteristic

Settings 30~600 SecUnit: 1 This parameter selects the time required for the electronic thermal protection function to activate.

When Pr.6-06 is set for 1 or 2 and the output current exceeds Pr.7-02 for the time set in Pr.6-07, the drive will fault with an OL1.

The common electronic thermal reaction time (150% output current for 1 minute) is shown in the chart below. The actual reaction time will vary depending on output current.
