Mitsubishi FR-A800

(A) Application parameters

PARAMETERS
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 the FR-A8AP (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 REMARKS
Position pulse monitor
When "19" is set in Pr.52 Operation panel main monitor selection, the position pulse monitor is
displayed instead of the output voltage monitor of the PU.
(Displayed only when the FR-A8AP (option) is mounted.)
Orientation status

When "22" is set in Pr.52, the orientation status is displayed instead of the output voltage monitor of
the PU. (Displayed only when the FR-A8AP (option) is mounted.)
0: Other than orientation operation or orientation speed is not reached
1: Orientation speed is reached
2: Creep speed is reached
3: Position loop is reached
4: Orientation complete
5: Orientation fault (pulse stop)
6: Orientation fault (orientation limit)
7: Orientation fault (recheck)
8: Continuous multi-point orientation
 Invalid during vector control. ("0" is always displayed.)
• The in-position width for orientation stop can be set.
The initial value of Pr.357 is "5". To change the 
 value,
make fine adjustments by changing in increments of
10.
• If the position detection value from the encoder enters 
during orientation stop, the Orientation complete signal
(ORA) will be output.
