9.11.4 Force Limiting Using an External Force Limit and Analog Voltage Reference

This function can be used to combine force limiting by an external input signal and by analog voltage reference.
Because the force limit by analog voltage reference is input from T-REF (CN1-9, 10), this function cannot be
used during force control. Use /P-CL (CN1-45) or /N-CL (CN1-46) for force limiting by external input signal.
When /P-CL (or /N-CL) is ON, either the force limit by analog voltage reference or the setting in Pn404 (or
Pn405) will be applied as the force 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.
2 is set, T-REF is used for force feed-forward input, but the functions cannot be used together.
