L7-01: Forward Torque Limit
No.
(Hex.)
Name Description
Default
(Range)
L7-01
(04A7)
RUN
Forward Torque Limit
Sets the torque limit value for forward motoring as a percentage, where motor rated torque is the
100% value.
200%
(0 - 300%)
Note:
• The lower torque limit is enabled when you set the torque limit by the following method.
– Set H3-02 or H3-10 = 10, 15 [MFAI Function Select = Forward Torque Limit, General Torque Limit] .
–
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.

Reverse Torque Limit
Sets the torque limit value for reversed motoring as a percentage, where motor rated torque is the
100% value.
200%
(0 - 300%)
Note:
•
The lower torque limit is enabled when you set the torque limit by the following method.
– Set H3-02 or H3-10 = 10, 15 [MFAI Function Select = Forward, Reverse/Regenerative Torque Limit] .

Forward Regenerative Trq
Limit
Sets the torque limit value for forward regenerative conditions as a percentage of the motor rated
torque.

Reverse Regenerative Trq
Limit
Sets the torque limit value for reversed regenerative conditions as a percentage of the motor rated
torque.

Note:
•
Use this method to set the torque limit and enable the lower torque limit:
–
Set H3-02 or H3-10 = 10, 15 [MFAI Function Select = Forward, Reverse/Regenerative Torque Limit] .
