◆ L7: TORQUE LIMIT
The torque limit function limits the internal torque reference for the drive to and keeps the torque from the motor
constant.
This function limits the torque applied to loads and regenerative torque to a value less than a set quantity. This
function also prevents damage to machinery and increases the reliability of continuous operation. You can set
torque limits individually for the four quadrants, which include torque direction (motoring/regeneration) and
direction of motor rotation (forward/reverse). When the torque reference value is at the set torque limit, the
MFDO terminal set for During Torque Limit [H2-xx = 30] activates.
Note:
• The drive output current limits maximum output torque. The drive limits torque to 150% of the rated output current for Heavy Duty
Rating (HD) and to 110% of the rated output current for Normal Duty Rating (ND). The actual output torque is not more than the limits
of the drive rated output current when you set the torque limit to a high value.
• When you use torque limits for lifting applications, do not lower the torque limit value too much. When the torque limit function is
triggered, falls and rollbacks can occur because of sudden acceleration stops and stalls of the motor.
■ Configuring Settings
Use one of these methods to set torque limits:
• Individually set the four torque limit quadrants using L7-01 to L7-04 [FW Torque Limit to RV Reg. TrqLimit].
