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.
