 Positioning by point tables (Pr.4 to Pr.6, Pr.24 to Pr.27, Pr.465 to Pr.478,
Pr.1222, Pr.1223, Pr.1225 to Pr.1227, Pr.1229 to Pr.1231, Pr.1233 to
Pr.1235, Pr.1237 to Pr.1239, Pr.1241 to Pr.1243, Pr.1245 to Pr.1247,
Pr.1249)
• Assign the target position, speed, and acceleration/deceleration time to point tables and select a table using the RH, RM,
and RL signals.
• Select the External operation mode or Network operation mode (the Ethernet connector or communication option is the
command source). (Point table selection signals are fixed to OFF in the Network operation mode while the PU connector
is the command source, or in the PU operation mode.)

*1 Position commands are accepted after the home position return operation is completed. New position data are not accepted during home position
return operation.
*2 A frequency higher than Pr.1 Maximum frequency cannot be set for the speed command. The Pr.2 Minimum frequency setting is disabled.
 Position data settings
• Set the position feed length in Pr.465 to Pr.478.
• The feed length set to each point table is selected by multi-speed terminals (RH, RM, and RL).
• Under Vector control with encoder, set the value calculated with the following formula as the position feed length: (encoder
resolution × rotations per minute × 4).
• For example, to stop the SF-PR-SC motor after 100 times of rotations, the value is calculated as follows:
2048 (pulses/rev) × 100 (rotations per minute) × 4 (multiplier) = 819200 (feed length)
To set 819200 as the first feed length, separate the number into the upper and lower four digits as follows:
Pr.466 (upper digits) = 81 (decimal), Pr.465 (lower digits) = 9200 (decimal)
 Acceleration/deceleration time setting
• Set the acceleration/deceleration time for parameters corresponding to each point table.

Setting range
The input logic can be selected for X87, LSP, and LSN.
Normally open: The operation is stopped when the contact
between SD and each signal is closed.
