d14 to d18
PG option Ch2 (Feedback input)
(Pulse input method), (Encoder pulse count), (Pulse scaling factor 1),
(Pulse scaling factor 2), (Pulse train command filter time constant)
Sets speed feedback input under vector control with speed sensor and V/f control with speed sensor.
 PG option Ch2 (Pulse input method) (D14)
d14 specifies the speed feedback input format.

3
Quadrature A/B signal
(A phase lead)
This setting is the inversion of d14 = 2. (Lead phase A Forward
rotation)
In case that YA and YB are reversely connected to the specified
terminals, setting “3” to this function code can reverse the
polarity of detected speed (position) without changing the
connection.

(B phase lead) UVW signal
(for synchronous motors)
If using a synchronous motor with UVW encoder, set to “4”.
 Feedback Input, Encoder pulse resolution (d15)
Set the encoder pulse count for speed feedback input.
• Data setting range: h.0014 to h.EA60 (hexadecimal fomat)
(20 to 60000 (P/R) when the above range is expressed in decimal format.)
If using a dedicated Fuji motor for vector control, set to “0400 (1024 P/R)”.
