8.9.4 Torque Limiting Using an External Torque Limit and Analog Voltage Reference

This function can be used to combine torque limiting by an external input signal and by analog voltage reference.
Because the torque limit by analog voltage reference is input from T-REF (CN1-9, 10), this function cannot be
used during torque control. Use /P-CL (CN1-45) or /N-CL (CN1-46) for torque limiting by external input signal.

When /P-CL (or /N-CL) is ON, either the torque limit by analog voltage reference or the setting in Pn404 (or
Pn405) will be applied as the torque limit, whichever is smaller.

Speed control option: When /P-CL or /N-CL is enabled, the T-REF terminal is used as the
external torque limit input.

When n.†††2 is set, T-REF is used for torque feed-forward input, but the functions cannot be used together.
