Over-torque detection (Mode selection)
Factory setting
d 0
Setting range
d 0
No detection
d 1
Over torque detection (OL2) during constant speed running, continue to run
after detection.
d 2
Over torque detection (OL2) during constant speed running, stop running
after detection.
d 3
Over torque detection (OL2) during acceleration and constant speed
running, continue to run after detection.
d 4
Over torque detection (OL2) during acceleration and constant speed
running, stop running after detection.
When this parameter sets the action of inverter when OL2 actuates, no action when set as 0. When set as other
values, the operation keypad will display OL2 error when OL2 actuates. d1 or d3 setting shows that the inverter
continues to operate after error occurs. The rest of OL2 error needs to its automatic reset after the error disappears
or stop the inverter and reset error simultaneously. d2 or d4 setting indicates that the inverter stops operating after
error happens. Press RESET key to reset OL2 error after 5 seconds. Determine whether setting this function at
constant speed or accelerated speed is more effective according to the actual usage.

Over-torque detection (Detection level)
Factory setting
d 150
Setting range
d 30<->d 200%
Unit
1%
Set Over torque detection level, unit shall be percentage of rated current (100%) of inverter.

Over-torque detection time
Factory setting
d 0.1
Setting range
d 0.1<->d 10.0s
Unit
0.1s
Over-torque detection method: This contactor shall be closed, if output current exceeds over torque detection level
(6-03 set value; factory setting: 150%) and 6-04 setting for over torque detection time (Factory setting: 0.1 sec) and if
“multifunctional output terminal” is set to over torque detection reference. See descriptions in 3-05.

d 0
Inactive
d 1
Active(For a general-purpose motor with shaft-driven cooling fan)
d 2
Active(For a motor with separately powered cooling fan)
To prevent over-heating in low speed running of self-cold motor, users shall set electric relay to control the output
frequency of inverter within allowable range.
