Sets a torque limit value when torque is restricted by external contact input.
This function is valid when bit 2 of memory switch Cn-02 is set to 0.
When P-CL (1CN-45) is input Applies torque restriction as specified in Cn-18
When N-CL (1CN-46) is input Applies torque restriction as specified in Cn-19
For torque restriction by analog voltage reference, refer to

Using P-CL
and N-CL Signals
This section describes how to use input signals P-CL
and N-CL as torque limit input sig-
nals.
