Delta Electronics VFD-G manual 06 - 03 Over-torque Detection Selection

Chapter 4 Parameters

06 - 03 Over-torque Detection Selection

	Factory Setting: 00
Settings	00: Over-torque detection disabled.
	01: Over-torque detection enabled during constant speed operation (OL2),
	and operation continues.
	02: Over-torque detection enabled during constant speed operation (OL2),
	and operation halted.
	03: Over-torque detection enabled during operation (OL2), and operation
	continues.
	04: Over-torque detection enabled during constant speed operation (OL2),
	and operation halted.

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		Unit: 1
	Settings	30~150%	Factory Setting: 110

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

06 - 05	Over-torque Detection Time		Unit: 0.1
	Settings	0.1~60.0 Sec	Factory Setting: 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

	Factory Setting: 02
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		Unit: 1
	Settings	30~600 Sec	Factory Setting: 60

This parameter selects the time required for the electronic thermal protection function to

activate.
