6.33.10 Overtorque trip
H : Overtorque trip selection
H
: Overtorque detection level during power running
H
: Overtorque detection level during regenerative braking
H
: Overtorque detection time
H
: Overtorque detection hysteresis
• Function
Trips the inverter or issues an alarm if the total time for which torque is above the level set with
H
/
H
reaches the time set with
H
. Trip information is displayed as “
QV
.”
H= (No trip)
・・・・・・・・ No tripping (FL is not active).
H= (Tripping)
・・・・・・・ The inverter will trip (the failure signal FL will be activated) if a torque larger than
H (during power running) or H (during regeneration) passes for a time
longer than the time set with H.
Title Function Adjustment range Default setting
H Overtorque trip selection
:No trip
:Trip
H Overtorque detection level during power running ~%
H Overtorque detection level during regenerative braking ~%
H Overtorque detection time ~ sec.
H Overtorque detection hysteresis ~%
Note:Using the output terminal function selection parameter, the inverter can be set so that it outputs overtorque
detection signals regardless of the setting of H.
⇒ Refer to Section 7.2.2.
<Example of operation>
Output terminal function: 28 Overtorque detection
H= (No trip)
Ex.) When outputting overtorque detection signals through output terminal OUT1
Title Function Adjustment range
Example of setting
H Output terminal function selection 1(OUT1) ~
Note:To put out signals to the terminal OUT2, select the parameter H.

When H= (tripping), the inverter will trip if overtorque lasts for the period of time set with H. In
such a case, the overtorque signal remains ON.
