(1) Setting of position feed amount by
parameter [Pr. 419 = 0, Pr. 465 to 494]
Set [Pr. 419 = 0] (initial value) and set position feed
amount in [Pr. 465 to 494].
The feed amount set in each parameter is selected
by multi-speed terminal (RH, RM, RL, REX).
Set (encoder resolution × speed × 4 times) for
position feed amount.
For example, when stopping the motor after 100
rotations using the SF-V5RU, 2048 (pulse/r) × 100
(speed) × 4 (multiplication) = 819200 (feed amount).
To set 819200 for the first position feed amount,
divide the value into upper four digits and lower four
digits and set 81 (decimal) in [Pr. 466] (upper) and
9200 (decimal) in [Pr. 465] (lower).

(2) Position
parameter
Information on multi-speed command (position
command) is determined at rising of the forward
(reverse) command to perform position control.
Therefore, set forward (reverse) command after
multi-speed command (position command by RL,
RM, RH, and REX signals). Position feed is invalid if
the multi-speed command is given after forward
(reverse) command.
For deceleration by turning the STF(STR) OFF, use
[Pr. 464 Digital position control sudden stop deceleration
time] to set deceleration time.
Acceleration/deceleration time is 0.1s minimum and
360s maximum.
[Pr. 20 Acceleration/deceleration reference frequency] is
clamped at a minimum of 16.66Hz (500r/min).
The acceleration/deceleration patterns for position
control are all linear acceleration and the setting of
[Pr. 29 Acceleration/deceleration pattern selection] is
invalid.
