6-03

Over-Torque Detection Mode (OL2)

Factory Setting: d0

Settings

Over-Torque detection disabled.

Enabled during constant speed operation. After the over-torque is
detected, keep running until OL1 or OL occurs.

Enabled during constant speed operation. After the over-torque is
detected, stop running.

Over-Torque detection enabled during running, and continues to run
till OL1 or OL.

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

Operate with a Standard Motor (self-cooled by fan)

Operate with a Special Motor (forced external cooling)

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

The parameter determines the time required activating the I

t electronic thermal protection

function. The graph below shows I

t curves for 150% output power for 1 minute.
