NOTE
• Values in parentheses indicate binary data input from the terminals. Even if the position pulse monitor (Pr.52 Operation
panel main monitor selection = "19") is selected, the data monitored is not the number of stop positions but is 0 to 65535
pulses.
• FR-A8AX parameters (Pr.300 to Pr.305) are invalid (Valid when Pr.360 = "0".)
• Terminal DY (data read timing input signal) becomes invalid during vector control. (The position data is downloaded at the
start of orientation.)
• Internal stop position command is given when no option is mounted or Pr.360 = "0" even if "1" (external stop position
command) is set in Pr.350.
• Relationship between stop position command and 16-bit data

Pr.361 Position shift (initial value "0")
• The stop position is a position obtained by adding the setting of Pr.361 to the position command.
• Position shift function
Shift the home position using a compensation value without changing the home position of the position detector (encoder).
NOTE
• When orientation control is valid using Pr.350 Stop position command selection with a vector control compatible option
mounted, the rotation direction of the encoder is displayed on the rotation direction display of the PU (operation panel/
parameter unit).
Make settings so that FWD is displayed at turn ON of the STF signal and REV is displayed at turn ON of the STR signal.
Monitor display change
• The following items can be monitored by the operation panel. (Refer to

Invalid during vector control. ("0" is always displayed.)
Pr.357 Orientation in-position zone (initial value "5")
• The in-position width for orientation stop can be set.
The initial value of Pr.357 is "5". To change the 
