Section L: Protection Parameters
L6 Torque Detection
Setting Range: 0 to 300%
Factory Default: 150%
Sets the overtorque detection level as a percentage of inverter rated current, during V/f control, and
motor rated torque, during vector control.
Setting Range: 0.0 to 10.0s
Factory Default: 0.1s
The overtorque detection delay time inserts a delay, between the time motor current (or torque)
exceeds the overtorque detection level (L6-02) and when the overtorque detection function is enabled.
The digital operator then displays “OL3”.
Activates overtorque detection 2, and selects whether detection generates an alarm or a fault.
Overtorque detection 2 functions the same as overtorque detection 1 (L6-01), except that “OL4” is dis-
played on the digital operator instead. This function is used when two types of detection are output to
the multi-function output terminals.
Setting Range: 0 to 300%
Factory Default: 150%
Sets the second overtorque detection level as a percentage of inverter rated current, during V/f control,
and motor rated torque, during vector control.

Setting Description
0 Overtorque detection is disabled (factory default).
1 Overtorque detection is enabled whenever at the speed agree level (when inverter is not
accelerating or decelerating). Continue running after detection (OL4 alarm).
2 Overtorque detection is enabled always. Continue running after detection (OL4 alarm).
3 Overtorque detection is enabled whenever at the speed agree level. Coast to a stop after
detection (OL4 fault).
4 Overtorque detection is enabled always. Coast to a stop after detection (OL4 fault).
