Application of the sine wave filter
For the FR-F700 series (75K or more) inverter, the motor voltage and current can be made to nearly sine wave shaped by providing a sine wave filter
on the output side.
1) Low noise
2) Surgeless
3) Motor loss reduction (use of standard motor)
Application condition
The following conditions have to be satisfied to install the sine wave filter.
1) Change the
2) The sine wave filter can be used only for 60 Hz or less inverter frequency.
Note that the filter can not be used for the higher frequency operation than this. (Otherwise the filter loss will increase. )
3) Use the inverter with capacity one rank higher. *2
4) Install an external thermal relay of the motor.

setting to "25". (The initial value is "2".)
The carrier frequency changes to 2.5KHz. (The sine wave filter is designed on condition that the carrier frequency is 2.5KHz. Be sure to change
the setting properly.) If the inverter is operated with Pr.72 set to other than "25", the inverter and sine wave filter may be damaged.
