Individual Functions6-137Speed Control (ASR) Gain Adjustment for Flux Vector Control (SPEC: E or Later Only)Use the following procedure to adjust C5-01 and C5-03 with the mechanical system and actual load con-nected.Fine AdjustmentsWhen you want even finer gain adjustment, adjust the gain while observing the speed waveform. Constant set-tings like those shown in the following table will be necessary to monitor the speed waveform.The multi-function analog outputs have the following functions with these constant settings.• Multi-function analog output 1 (terminal FM): Outputs Inverter's output frequency (0 to ±10 V).• Multi-function analog output 2 (terminal AM): Outputs actual motor speed (0 to ±10 V).Terminal AC is the multi-function analog output common.We recommend monitoring both the output frequency and the motor speed to monitor the response delay ordeviations from the reference value, as shown in the following diagram.ConstantNo. Name Setting ExplanationH4-01 Multi-function analog output 1 terminal FM monitor selection 2 Settings that allow multi-func-tion analog output 1 to be usedto monitor the output frequency.H4-02 Multi-function analog output 1 terminal FM output gain 1.00H4-03 Multi-function analog output 1 terminal FM bias 0.0H4-04 Multi-function analog output 2 terminal AM monitor selection 5 Settings that allow multi-func-tion analog output 2 to be usedto monitor the motor speed.H4-05 Multi-function analog output 2 terminal AM output gain 1.00H4-06 Multi-function analog output 2 terminal AM bias selection 0.00H4-07 Multi-function analog output 1 terminal signal level selection 1 Settings that allow a 0 to ±10 Vsignal range to be monitored.H4-08 Multi-function analog output 2 terminal signal level selection 1At zero-speed, increase C5-01(ASR P Gain 1) until there is no oscillation.At zero-speed, decrease C5-02(ASR I Time 1) until there is no oscillation.Does oscillation develop when the motoroperates at the maximum normal operatingspeed?Decrease C5-01 (ASR P Gain 1).Increase C5-02 (ASR I Time 1).YESNOAdjustment completed.(When there is higher-level position control,adjust the position loop gain so thatovershooting/undershooting doesn't occur.)
