ORIENTATION CONTROL AT A MACHINE END— V500
6.5 Parameter Setting
If the orientation command signal (X22) is turned on during operation after the various parameters have
been set, the speed will decelerate to the "orientation switchover speed". After the "orientation stop
distance" is calculated, the speed will further decelerate, and the "orientation state" (servo lock) will be
entered. The "orientation complete signal" (ORA) will be output when the "orientation complete width" is
entered.

Orientation control invalid
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 degrees) is
divided into 4096 positions, i.e. 360 degrees/4096
pulses = 0.0879 degrees/pulses per address, as
shown on the right. The stop positions
(addresses) are indicated in parentheses.
