3.27 Orientation (Pr. 350 to Pr. 362, Pr. 393 to Pr. 399)
3.27.1 Orientation control (Pr. 350, Pr. 351, Pr. 356, Pr. 357, Pr. 360 to Pr. 362, Pr. 393,
Pr. 396 to Pr. 399 )
<Settings>
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.
(1) Setting I/O singals
Orientation is a function that stops a motor shaft at a position set by parameter using the motor built-in
position detector (encoder). Install the option (FR-V5AM or FR-A5AP) on the inverter to perform stop position
command control with a position detector (encoder) fitted to the machine. Refer to the instruction mannual of
the option for details.
Pr. 350 "stop position command selection" is factory-set to "9999" to make the orientation control function
invalid.

REMARKS
Check the Pr. 851 and Pr. 852 settings. (Refer to the Insruction Manual (basic).)
Input Orientation command X22 signal
Orientation control is valid with the signal on.
Set "22" in any of Pr. 180 to Pr.183 or Pr. 187 (input
terminal function selection). (Refer to page 150.)
Output Orientaiton complete signal ORA signal
Switched low if the orientation has stopped within the
in-position zone while the start and orientation signals
are input.
Open collector output
Permissible load 24VDC, 0.1A
Set 27 in any of Pr.190 to Pr. 192 or Pr. 195 (output
terminal function selection).
