6 -40 Adjusting Frequency Reference Using Pulse Train InputsThe frequency reference can be adjusted when b1-01 (Reference Selection) is set to 4 (Pulse Train Input). Setthe pulse frequency in constant H6-02 to 100% reference, and then adjust the gain and bias accordingly usingH6-03 and H6-04.Related ConstantsThe following diagram shows the method for adjusting the frequency reference using pulse inputs.Fig 6.33 Frequency Reference Adjustments Using Pulse Train InputsCon-stantNumberName Description SettingRangeFactorySettingChangeduringOpera-tionControl Methods MEMOBUSRegis-terV/fV/fwithPGOpenLoopVec-torFluxVec-torH6-01Pulse traininput functionselection0: Frequency reference1: PID feedback value2: PID target value0 to 2 0 No A A A A 42CHH6-02 Pulse traininput scalingSet the number of pulses inhertz, taking the reference to be100%.1000 to32000 1440 Hz Yes A A A A 42DHH6-03 Pulse traininput gainSet the input gain level as a per-cent when the pulse train set inH6-02 is input.0.0 to1000.0 100.0% Yes A A A A 42EHH6-04 Pulse traininput biasSet the input bias when the pulsetrain is 0.-100.0to 100.0 0.0% Yes A A A A 42FHH6-05Pulse traininput filtertimeSet the pulse train input primarydelay filter time constant in sec-onds.0.00 to2.00 0.10 s Yes A A A A 430HRP CyclemeasurementFilterH6 - 05H6 - 01Master speedfrequencyPID feedbackPID target value=0=2=1Scaling using H6-02Gain and biasPulse11+sT0H6 - 04H6 - 03100
