Orientation (Pr. 350 to Pr. 362, Pr. 393 to Pr. 399)
(2) Selecting stop position command
Select either the internal stop position command (Pr. 356) or the external stop position command (6/12/16-bit data).

(1) Internal stop position command (Pr. 350 = "0")
The value set in Pr. 356 is the stop position.
When the number of encoder pulses is 1024p/r, one revolution
of the encoder (360 ) is divided into 4096 positions, i.e. 360
°
4096 pulses = 0.0879 /pulses per address, as shown on the
°
right. The stop positions (addresses) are indicated in
parentheses.
(2)-1 External stop position command (Pr. 350 = "1")
(Pr. 360 "external position command selection" (factory setting: 0))
Mount the option FR-V5AX and set a stop position using 6-bit data (binary input).
• The value set in Pr. 360 "external position command selection" should be the number of stop positions less 1.

Orientation control invalid
External position command is made invalid (multi-function input with the FR-V5AX)
Set 64 stop positions at regular intervals
Set the stop position command dividing up to 128 stop positions at regular intervals. If the external
stop command entered is greater than the setting, the stop positions are the same as those in the
maximum external stop command value. Note that the stop command greater than the 64 stop
positions can not be entered if the number of stop positions are 65 to 128.
<Example>
When the number of stop positions is 20 (divided at intervals of 18°), 20 - 1 = 19. Hence, set "19".

Set 4096 stop positions at regular intervals
Set the stop position command dividing up to 128 stop positions at regular intervals. If the external
stop command entered is greater than the setting, the stop positions are the same as those in the
maximum external stop command value.
<Example>
When the number of stop positions is 90 (divided at intervals of 4°), 90 - 1 = 89. Hence, set "89".
