5 Adjustments5.1.3 Monitoring Operation during Adjustment5-45.1.3 Monitoring Operation during AdjustmentCheck the operating status of the machine and signal waveform when adjusting the servo gain. Connect a mea-suring instrument, such as a memory recorder, to an analog monitor connector on the multi-winding drive unitto monitor the analog signal waveform. The settings and parameters for monitoring analog signals aredescribed in the following sections.(1) Analog Monitor Connections(2) Monitor SignalThe shaded parts in the following diagram indicate analog output signals that can be monitored.∗ The above diagram shows a multi-winding drive system that includes a multi-winding drive unit, SERVOPACKs, andconverters.Connector PinNumber Signal Name Factory SettingCN1-16 Analog monitor 1 (TMON) Torque reference: 1 V/100% rated torqueCN1-17 Analog monitor 2 (VTG-M) Motor speed: 1 V/1000 min-1CN1-1 Signal ground (SG) Analog monitor GND: 0 VKpU1/V1/W1U2/V2/W2-++-+ + +TorquereferenceSpeedreferencePositionreference+-+ 1Multi-winding drive systemSpeed feedforwardPosition reference speedPosition amplifier errorMotor speedSpeed referenceActive gain Torque referenceSpeedconversionBacklashcompen-sationElectronicgearSpeedloopCurrentloopElectronicgearPosition loopTorque feedforwardErrorcounterErrorcounter MKpPosition errorPositioning completedCompletion ofposition referenceSpeedconversionENCCN21
