Chapter 7 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“.

Input
The pulse train position

signal. (STAT)
Set ‘48’ to one of
C001∼C008
Pulse train position command input
is valid while ON.
Output
Positioning completion
signal.(POK)
Set ‘23’ to one of
C021∼C025
Output when it entered into the
positioning completion range
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 P019P021 is shown. (Yet, the encoder pulse number of the master side and slave
side are same and be in the case of 1024 pulses. )
