Parameters (A) Application parameters
FR-A800 5 - 509
●
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).
NOTES 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.

Tab. 5-213: Relation between parameters 350 and 360
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.
