Note:
•
When you use this method to set the torque limit, it enables the lower torque limit:
–
Set H3-02 , H3-06 , or H3-10 = 10, 15 [MFAI Function Select = Forward, Reverse/Regenerative 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.
