Inputting the number of pulses (positions) in the parameters and
setting multi-speed and forward (reverse) commands enable
position control during servo operation.This position feed function
does not return to the home position.
Set position command using any two of Pr. 465 to Pr. 494 (position
feed amount).

(When stopping the motor after 100 rotations using the FR-V5RU)
2048 (pulse/rev) × 100 (speed) × 4 = 819200 (feed amount)
Setting of the first feed amount 819200
Pr.466 (upper) = "0081" Pr.465 (lower) = "9200" (decimal)

Position control by pulse train input of the inverter

Pr.419 Position command source selection
Pr.429 Clear signal selection
Conditional position pulse train command can be input by pulse
train input and sign signal (NP) from the JOG terminal.
When 2 is set in Pr.419, conditional pulse train position command is
selected.
Select command pulse train using Pr.428.
Turning on (short the terminal LX-SD) the servo on signal cancels
the base circuit shut-off. When the terminal STF (forward rotation
stroke end signal) or terminal STR (reverse rotation stroke end
signal) and terminal SD are shorted at this time, the motor starts
rotating in accordance with the command pulses. When the forward
(reverse) rotation stroke end signal is opened, the motor does not
run in the corresponding direction.
