Adjustment Suggestions4- 19* The setting is given for 200 V Class Inverters. Double the voltage for 400 V Class Inverters.• Do not change the Torque Compensation Gain (C4-01) from its default setting of 1.00 when using open-loop vector control.• If speeds are inaccurate during regeneration in open-loop vector control, enable Slip Compensation DuringRegeneration (C3-04 = 1).• Use slip compensation to improve speed control during V/f control (A1-02 = 0).Set the Motor Rated Current (E2-01), Motor Rated Slip (E2-02), and Motor No-load Current (E2-03), andthen adjust the Slip Compensation Gain (C3-01) to between 0.5 and 1.5. The default setting for V/f controlis C3-01 = 0.0 (slip compensation disabled).Open-loopvector con-trol (A1-02= 2)Carrier frequencyselection (C6-02)• Reducing motormagnetic noise• Controlling huntingand vibration at lowspeeds (10 Hz orless)1(C6-01=0)0 todefault• Increase the setting ifmotor magnetic noise ishigh.• Reduce the setting if hunt-ing or vibration occurs atlow speeds.Dependson capac-ity(C6-01=1)Middle output fre-quency voltage(E1-08)Minimum output fre-quency voltage(E1-10)• Improving torque atlow speeds• Controlling shock atstartupDependson capac-ity andvoltageDefault toDefault + 3to 5 V *• Increase the setting iftorque or speed response isslow.• Reduce the setting if shockat startup is large.Flux vectorcontrol(A1-02 = 3)ASR proportional gain1 (C5-01) andASR proportional gain2 (C5-03)• Torque and speedresponse• Controlling huntingand vibration20.00 10.00 to50.00• Increase the setting (byincrements of 5) if torqueor speed response is slow.• Reduce the setting if hunt-ing or vibration occurs.ASR integral time 1(high-speed) (C5-02)andASR integral time 2(low-speed) (C5-04)• Torque and speedresponse• Controlling huntingand vibration0.500 s 0.300 to1.000 s• Reduce the setting iftorque or speed response isslow.• Increase the setting if hunt-ing or vibration occurs.ASR switching fre-quency (C5-07)Switching the ASRproportional gain andintegral time accord-ing to the output fre-quency0.0 Hz0.0 to max.output fre-quencySet the output frequency atwhich to change the ASRproportional gain and inte-gral time when the same val-ues cannot be used for bothhigh-speed and low-speedoperation.ASR primary delaytime (C5-06)• Controlling huntingand vibration 0.004 s 0.004 to0.020 s• Reduce the setting (byincrements of 0.01) iftorque or speed response isshow.• Increase the setting ifmachine rigidity is low andthe system vibrates easily.Carrier frequencyselection (C6-02)• Reducing motormagnetic noise• Controlling huntingand vibration at lowspeeds (3 Hz or less)1(C6-01=0)2.0 kHz todefault• Increase the setting ifmotor magnetic noise ishigh.• Reduce the setting if hunt-ing or vibration occurs atlow to middle-rangespeeds.Dependson thecapacity(C6-01=1)Table 4.5 Adjusted User Constants (Continued)ControlMethodName (ConstantNumber) Performance FactorySettingRecom-mendedSettingAdjustment Method
