This torque limiting function cannot be used at the same time as the torque feed-forward func-
tion.
Confirm the allocation of input signals when using this function. (Refer to 5.3.3 Input Circuit
Signal Allocation.) The factory settings are shown in the following table.
/P-CL
ON and CN1-45 is low
OFF and CN1-45 is high
/N-CL
ON and CN1-46 is low
OFF and CN1-46 is high
J J Setting
The torque limit input gain is set at user constant Pn400.
The factory setting at Pn400 is 30. If, for example, the torque limit is ±3 V, then torque is limited
to 100% of the rated torque. (A torque value higher than 100% torque is clamped at 100%. A
100% torque will also be used as the limit if the input torque limit value is - - 3 V.)

The settings of the following user constants are also valid. The torque limit will be either the
torque limit value for the analog voltage reference or the setting of Pn404/Pn405, whichever is
smaller.
