actory Setting: d 0
Settings d 0 Over-Torque detection disabled.
d 1 Over-Torque detection enabled during constant speed
operation (OL2), and operation continues until the
continuous operation limit (Pr.6-04) is reached.
d 2 Over-Torque detection enabled during constant speed
operation, and operation halted after over-torque
detection.
d 3 Over-Torque detection enabled during acceleration, and
operation continues before the Continuous Output Time
Limit (Pr.6-04) is reached.
d 4 Over-Torque detection enabled during acceleration.
Operation halted after over-torque detection

actory Setting: d 0.1
Settings d 0.1 to d 10.0 sec Unit: 0.1sec

This parameter determines the time that AC drive will run after over-torque is detected.
Over-torque detection is based on the following:
If a Multi-Function Output Terminal is set as Over-Torque Detection Indication and the
output current exceeds the Over-Torque Detection Level (Pr.6-04, Factory Setting:
150%), the output will be activated.

lectronic Thermal Overload Relay Selection Factory Setting: d 0
Settings d 0 Not used
d 1 Act with standard motor
d 2 Act with special motor

This function is used to limit the output power of the AC drive when powering a
“self-cooled motor” at low speed.
