6-03Over-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”.

6-06Electronic 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

 

 

 

 

 

The parameter determines the time required activating the I2t electronic thermal protection function. The graph below shows I2t curves for 150% output power for 1 minute.
