Motor brake and stop operation
Example 1: Pr. 369 = 1024
NOTES Values in parentheses indicate binary data entered from the terminals. Even if the position
pulse monitor (Pr. 52 DU/PU main display data selection = 19) is selected, the data monito-
red is not the number of stop positions but is 0 to 65535 pulses.
FR-A7AX parameters (Pr. 300 to Pr. 305) are invalid. (Valid when Pr. 360 = "0")
Terminal DY (data read timing input signal) is made invalid during vector control. (The posi-
tion data is downloaded at the start of orientation.)
Internal stop position command is given even if "1" (external stop position command) is set
in Pr. 350 when an option card (FR-A7AX) is not mounted or Pr. 360 = "0".
Relationship between stop position command and 16-bit data.

0: internal

Tab. 6-75: Relation between parameters 350 and 360
Parameter 361: Position shift
The stop position is a position obtained by adding the setting value of Pr. 361 to the position com-
mand.
The position shift functions shift the origin using a compensation value without changing the ori-
gin of the poisition detector (encoder).
NOTE When orientation control is made valid using Pr. 350 "Stop position command selection" with
the FR-A7AP mounted, the rotation direction of encoder is displayed on the rotation direction
display of the PU (FR-DU07/FR-PU04/FR-PU07).
Set the parameter so that turning on the STF signal displays FWD or turning on the STR
signal displays REV.
