Confirm the allocation of input signals when using this function. (Refer to 4.3.3 Input Cir-
cuit Signal Allocation.) Factory settings are given in the following table.
„ Setting
The torque limit input gain is set at parameter 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 parameters 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.
