4-54 Revision July 2008, EG03, SW V1.06
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.
