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 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 Factory Setting: 0.1
Settings 0.1~60.0 Sec Unit: 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 Factory Setting: 60
Settings 30~600 Sec Unit: 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.
