• 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 tr ipping (FL is not active).
H= (Tripping) ············ The inverter will trip (the failure signal FL will be activated) if a to rque larger than
H (during power running) or H (during regeneration) passes for a ti me
longer than the time set with H.

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.

When H= (tripping), the inverter will trip if overtorque lasts for th e period of time set with H. In
such a case, the overtorque signal remains ON.
6.33.11 Cooling fan control selectionHHHH : Cooling fan control selection

• Function

With this parameter, you can set the condition of cooling fan so that it operates only when the inverter

requires cooling, and thus it can be used for a longer period.

H=: Automatic control of cooling fan, enabled. Operates onl y when the inverter is in operation.
H=: Automatic control of cooling fan, disabled. The cooli ng fan always operates when the inverter is
energized.
