Túlnyomaték felismerési szintje

Factory Setting: d 150

Settings d 30 to d 200% Unit: 1%

! A setting of proportional to the Rated Output Current of the drive.

6 - 05 Time setting for Over-torque Detection Factory Setting: d 0.1

Settings d 0.1 to d 10.0 sec Unit: 0.1sec

! 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: d 2

Settings d 0 Reduce Torque Motor

d 1 Constant Torque Motor

d 2 Inactive

! This function is used to limit the output power of the AC drive when powering a

“self-cooled motor” at low speed.

6 - 07 Electronic Thermal Characteristic Factory Setting: d 60

Settings d 30 to d 600Sec Unit: 1 Sec

This parameter can be set during operation.

! The parameter determines the time required activating the I
