When using the torque limiting with the external torque limit and analog voltage reference, make sure that there are no
other signals allocated to the same terminals as /P-CL and /N-CL. When multiple signals are allocated to the same terminal,
the signals are handled with OR logic, which affects the ON/OFF state of the other signals. Refer to
7.3.2 Input Circuit Sig-
