Countermeasure against harmonics

Perform calculation given in the harmonic suppression guidelines, and if the limit value is exceeded, you may also need to insert the ACL. Note that you cann... More Details >>

Energy saving and power supply capacity of inverter

Energy saving is achieved by switching from the commercial power supply to the inverter to operate the motor. When the inverter reduces motor speed, it also... More Details >>

Inverter selection when multiple inverters are to be connected

Be sure to use a high power factor converter with the capacity higher than the total capacity of the inverters connected. (Note: One or more of the inverters... More Details >>

Comparison of noise with FR-A200

The setting ranges of the carrier frequency are:- FR-A200: 2 kHz to 14.5 kHz- FR-A200EXCELLENT: 0.7 kHz to 14.5 kHzThe range of the FR-A200E is extended to t... More Details >>

Can I change the carrier frequency?

You can change it by changing the setting of Pr.72 (PWM frequency selection). Setting range of Pr.72: 0, 1, 2, 3, 4, 5, 6 (Initial setting is "6".) (The smal... More Details >>
