10.3 Monitoring Machine Operation Status and Signal Waveforms10.3.3 Using a Measuring Instrument10-1110 Monitoring Adjustment ExampleAn example of adjusting the output of the motor speed monitor is provided below. PreparationsConfirm the following condition before you adjust the analog monitor output.• The parameters must not be write prohibited. Applicable ToolsYou can use the following tools to adjust analog monitor outputs. The function that is used isgiven for each tool.• Offset AdjustmentOffset Adjustment Gain AdjustmentThe gain adjustment range is made using a 100% out-put value (gain adjustment of 0) as the reference valuewith an adjustment range of 50% to 150%.A setting example is given below.• Setting the Adjustment Value to -125100 + (-125 × 0.4) = 50 [%]Therefore, the monitor output voltage goes to 50%of the original value.• Setting the Adjustment Value to 125100 + (125 × 0.4) = 150 [%]Therefore, the monitor output voltage goes to 150%of the original value.• The adjustment values do not use parameters, so they will not change even if the parame-ter settings are initialized.• Adjust the offset with the measuring instrument connected so that the analog monitor out-put value goes to zero. The following setting example achieves a zero output.• While power is not supplied to the Servomotor, set the monitor signal to the torque refer-ence.• In speed control, set the monitor signal to the position deviation.Tool Function Operating Procedure ReferenceDigital Operator Fn00C Σ-7-Series Digital Operator Operating Manual(Manual No.: SIEP S800001 33)SigmaWin+ Setup - Adjust Offset Operating Procedure on page 10-12Analog monitor output voltageOffset adjustmentMotor speed1 [V]1000 [min-1]Analog monitor output voltageGainadjustmentMotor speedItem SpecificationOffset Adjustment Range -2.4 V to 2.4 VAdjustment Unit 18.9 mV/LSBItem SpecificationGain Adjustment Range 100 ±50%Adjustment Unit 0.4%/LSBInformation
