(2) Measures of inverter
⋅ If a large value is set in Pr. 72 PWM frequency selection, decrease the Pr. 72 setting. (Noise from the motor
increases.)
⋅ Increase the setting of speed (torque) setting filter Pr. 822, Pr. 832 (Pr. 826, Pr. 836) .
CAUTION
As changing the speed (torque) setting filter will affect the response level of the inverter to the command,
adjust the setting by looking at the machine movement.
(3) Measures of option
⋅ Install the line noise filter FR-BLF (FR-BSF01 for the 3.7K or lower).
REMARKS
⋅ Refer to the Inverter Manual for details of measures for EMI.
