6-03 Over-Torque Detection Mode (OL2)
Factory Setting: d0
Settings d0 Over-Torque detection disabled.
d1 Enabled during constant speed operation. After the over-torque is
detected, keep running until OL1 or OL occurs.
d2 Enabled during constant speed operation. After the over-torque is
detected, stop running.
d3 Over-Torque detection enabled during running, and continues to run
till OL1 or OL.
d4 Enabled during running. After the over-torque is detected, stop
running.
6-04 Over-Torque Detection Level Unit: 1
Settings d30 to d200% Factory Setting: d150
This setting is proportional to the Rated Output Current of the drive.
6-05 Over-Torque Detection Time Unit: 0.1
Settings d0.1 to d10.0 sec Factory Setting: d0.1
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 Over-
Torque Detection Time (Pr.6-05, Factory setting: 0.1) and the setting of multi-function terminal
is Over-Torque Detection Indication, the contact will be “close”.
6-06 Electronic Thermal Overload Relay Selection
Factory Setting: d2
Settings 0 Operate with a Standard Motor (self-cooled by fan)
1 Operate with a Special Motor (forced external cooling)
2 Operation disabled
This function is used to protect the motor from overloading or overheating.
6-07 Electronic Thermal Characteristic Unit: 1
Settings d30 to d600Sec Factory Setting: d60
