Parameters Details
Explanation of Set Values
Set the torque limit method for forward and reverse direction.
If this parameter is set to 0, the forward and reverse torque limit input will be limited by the No. 1
Torque Limit (Pn013).
When using torque control, the No. 1 Torque Limit (Pn013) will be the limit value for forward and
reverse operation regardless of the setting of this parameter.
Set the limit value for the output torque (Pn013: No. 1 Torque Limit, Pn522: No. 2 Torque Limit) of
the motor.
Refer to information on the Torque Limit Selection (Pn521) to select the torque limits.
During torque control, maximum torques for both forward and reverse directions are limited.
Settings in Torque Limit Selection (Pn521) and No. 2 Torque Limit (Pn522) will be ignored.
Make the settings as a percentage of the rated torque. [Example] Maximum torque is limited to 150%
Refer to "5-3 Torque Control" (P.5-12) for more information on torque limits and the torque limit selection.
