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
The parameter determines the time required activating the I
2
t electronic thermal protection
function. The graph below shows I
2
t curves for 150% output power for 1 minute.
