FUNCTIONS

 

 

(Note 3) : N/D must be given as the ranges of 1/50 ≤ (N/D) ≤ 20.

 

(N: Electronic gear ratio numerator, D: Electronic gear ratio denominator)

(Note 4) : It depends on what type of main body combines with the SJ-FB, the setting

value conversion is different. Please refer to the (Note 3) of the “5.3 Items

regarding the feed back board of the inverter main body“.

Set ‘48’ (the pulse train position command input permission signal (STAT)) to one of C001∼ C008. Pulse train position command input is valid only in the case that the STAT terminal is turned ON. In the case that the STAT terminal is OFF or unestablished, pulse train position command input is invalid.

Below the example of the proportion of the slave side turn number to the master side turn number by the setting of P019￿P021 is shown. (Yet, the encoder pulse number of the master side and slave side are same and be in the case of 1024 pulses. )
