Parameters
Positioning by a point table (Pr. 4 to Pr. 6, Pr. 24 to Pr. 27, Pr. 232 to Pr. 239, Pr. 465 to Pr. 494,
Pr. 1222 to Pr. 1281)
● Create a the point table by setting the following parameters.

Position data settings
● Set the position feed length to Pr. 465 to Pr. 494.
● The feed length set to each point table is selected by multi-speed terminals (RH, RM, RL and REX).
● Under vector control with encoder, set the value calculated with the following formula as the
position feed length: (encoder resolution × number of rotations × 4).
● For example, to stop the motor after 100 times of rotations using SF-V5RU, the value will be
calculated with 2048 (pulse/r) × 100 (rotations per minute) × 4 (multiplier) = 819200 (feed length)
To set 819200 as the first feed length, separate the number in to the upper and lower 4 digits as
shown below:
● Pr. 466 (upper) = 81 (decimal), Pr. 465 (lower) = 9200 (decimal)
● The position feed length of PM sensorless vector control is fixed at 4096 for each motor rotation.
Acceleration/deceleration time
● Set the acceleration/deceleration time for parameters corresponding to each point table.
● The frequency that will be the basis of acceleration/deceleration time is Pr. 20 "Acceleration/
deceleration reference frequency." However, 1 Hz/s is the minimum acceleration/deceleration rate
(acceleration/deceleration frequency divided by acceleration/deceleration time). If the accelera-
tion/deceleration rate is smaller than 1, the motor runs at 1 Hz/s or in the deceleration time.
● The maximum acceleration/deceleration time is limited at 360 s.
● During position control, acceleration/deceleration pattern is always the liner acceleration/decel-
eration, and the Pr. 29 "Acceleration/deceleration pattern selection" setting is ignored.
