settings.
Setting
The torque limit is set at parameter Pn400.
The default setting at Pn400 is 30. If, for example, the torque limit is ±3V, then
torque is limited to 100% of the rated torque. (A torque value higher than 100%
torque is clamped at 100%.)
When either the P-CL or the N-CL signal is turned ON, the following torque limits
become valid simultaneously.
