Note:
• The lower torque limit is enabled when you set the torque limit by the following method.
–Set H3-02, H3-06, or H3-10 = 9, D [AI Function Select = FW Trq Lim, GenerTrqLim].
–Use a communication option to set the torque limits
• You must think about drive capacity when a large quantity of torque is necessary. If you set the value too high, the drive can detect oC
[Overcurrent].
• If you set the value too low with large loads, the motor can stall.

L7-06 TrqLimit Integral Time
(04AC)
Decrease the setting value to increase torque limit responsiveness when you use torque limits and L7-07 = 1
[TrqLimit@Acc/Decel = P-ctrl@Ac/Dec].
If there is hunting when torque limits are active, increase the setting value.

V/f CL-V/f OLV CLV AOLV
Sets the torque limit value for reversed motoring as a percentage, where motor rated torque is the
100% value.
V/f CL-V/f OLV CLV AOLV
Sets the torque limit value for forward regenerative conditions as a percentage of the motor rated
torque.
V/f CL-V/f OLV CLV AOLV
Sets the torque limit value for reversed regenerative conditions as a percentage of the motor rated
torque.
V/f CL-V/f OLV CLV AOLV
Sets the integral time constant for the torque limit function.
