Output current fluctuation damping

When the motor is driven, the output current of the inverter may fluctuate (current fluctuation) due to
the motor characteristics or the backlash at the load machine side. This parameter increases the 1st
Output Current Fluctuation Damping Gain (3008Hex-51Hex) and 2nd Output Current Fluctuation
Damping Gain (3009Hex-2AHex) when the control function for suppressing such current fluctuation is
to be adjusted.
Parameter No.
3008Hex-51Hex/
3009Hex-2AHex
• If inappropriate adjustments are made, the current fluctuation may increase. Therefore, do not
change the factory default set values, unless required.

Pulse Train Frequency Input

Pulse train input can be used for the frequency reference, operation target used for frequency refer-
ence and PID feedback value in PID control.
• To use pulse train input for the frequency reference, set Frequency Reference Selection
(3004Hex-02Hex/3006Hex-1FHex) to "12: Pulse train input."
• To use pulse train input for the operation target, set Frequency Reference Selection
(3004Hex-02Hex/3006Hex-1FHex) to "13: Calculation result" and set Frequency Calculation Opera-
tion Target 1/2 (301FHex-20Hex/301FHex-21Hex) to "5: Pulse train frequency."
• To use pulse train input for PID feedback, set PID Control Feedback Selection (301FHex-14Hex) to
"3: Pulse train input."
• Pulse train input uses input terminals [PIA], [PIB] and [PIZ].
