Position control under vector control
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, and 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 an encoder with 2048 pulses/rev,
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)
