6.1 Type of Adjustments and Basic Adjustment Procedure6-56 Adjustments6.1.3 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 are described in the following sections.(1) Analog Monitor Connector Connections(2) Monitor SignalThe shaded parts in the following diagram indicate analog output signals that can be monitored.Connector PinNo. 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 V(U/V/W)−++−+ + +T-REFV-REFPULSSIGN+−−+ 1Multi-winding drive systemSpeed feedforwardPosition reference speedPositionamplifier errorMotor rotationalspeedSpeed referenceActive gain TorquereferenceSpeedconversionElectronicgearSpeedloopCurrentloopElectronicgear1ElectronicgearPosition loopTorque feedforwardErrorcounterErrorcounterErrorcounterLoadMKpPosition errorPositioningcompletedCompletion of positionreferenceExternal encoder speedSpeedconversionSpeedconversionMotor - loadposition errorENCCN2CN 1ExternalENC**ReferencePulseMultiplier× n
