Multi-Speed Operation Connection Example

REMARKS

*1: When the frequency setting potentiometer is connected, the input signal of the frequency setting potentiometer is ignored if the multi-speed select signal is switched on. (This also applies to the 4 to 20mA input signal.)

*2: For a reverse rotation start, set Pr. 63 to "- - -" (factory setting).
