8.9 Limiting Torque8.9.4 Torque Limiting Using an External Torque Limit and Analog Voltage ReferenceThis 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 beused 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 (orPn405) will be applied as the torque limit, whichever is smaller.SERVOPACK/P-CL/N-CLTorque limitvalueT-REFPn400Forward torquelimit value (Pn402)SpeedreferenceV-REFPn300+-Speed loopgain(Pn100)Speed loopintegraltimeconstant(Pn101)++Pn405( /N-CL : ON)Reverse torquelimit value (Pn403)Pn404( /P-CL:ON)TorquereferenceSpeed feedback(1) Related ParametersParameterMeaningPn002 n.3 Speed control option: When /P-CL or /N-CL is enabled, the T-REF terminal is used as theexternal torque limit input.When n.2 is set, T-REF is used for torque feed-forward input, but the functions cannot be used together.Pn404 Forward External Torque LimitSpeed Position TorqueSetting Range Setting Unit Factory Setting Setting Validation0 to 800 % 100 ImmediatelyPn405 Reverse External Torque LimitSetting Range Setting Unit Factory Setting Setting Validation0 to 800 % 100 Immediately* The setting unit is a percentage of rated torque (i.e., the rated torque is 100%).88-73
