*2 During position control under Vector control, if Pr.419 = "1" while the FR-A8AL is not installed (or is disabled), a protective function (E.OPT) is
activated.
*3 During position control under Vector control, if Pr.419 = "1110 or 1310" while the FR-A8APS is not installed (or is disabled), a protective function
(E.OPT) is activated.
 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 the SF-V5RU,
The value is calculated with 2048 (pulses/rev) ×100 (rotations per minute) × 4 (multiplier) = 819200 (feed length)
