Selecting stop position command (Pr. 350)
Select either the internal stop position command (Pr. 356) or the external stop position com-
mand (16-bit data using the FR-A7AX).
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 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.
External stop position command (Pr. 350 = 1)
Mount the option FR-A7AX and set a stop position using 16-bit data (binary input). The value set
in Pr. 360 "16 bit data selection" should be the number of stop positions less 1.

Position command direct input
The 16-bit digital signal from the FR-A7AX is directly serves as stop position command.
Example
When the Pr. 369 Number of encoder pulses setting is 1024, stop position command from 0 to 4095
can be directly input using the FR-A7AX and input digital signal of 2048 (H800) to stop the motor at
180° position. Thecommand more than 4096 is considered as 4095.
2 to 127
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".
