Mitsubishi Electric FR-A820-00046 Instruction Manual page 687

Parameters
Connect the recommended 2W1kΩ resistor between the terminal PC and OH. (Recommended
product: MOS2C102J 2W1kΩ by KOA Corporation)
Insert the input line and the resistor to a 2-wire blade terminal, and connect the blade terminal to
the terminal OH. (For the recommended 2-wire blade terminals, refer to page 2-44.)
Insulate the lead wire of the resistor, for example by applying a contraction tube, and shape the
wires so that the resistor and its lead wire will not touch other cables. Caulk the lead wire securely
together with the thermal protector input line using a 2-wire blade terminal. (Do not subject the
lead wire's bottom area to an excessive pressure.)
To use a terminal as the terminal OH, assign the OH (external thermal O/L relay input) signal to an
input terminal. (Set "7" in any of Pr.178 to Pr.189. For details, refer to the Instruction Manual
(Detailed) of the inverter.)

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 com-
plete width" is entered.

Description
Use a terminal to input the orientation signal that commands orientation.
Orientation command
For the X22 signal input, set "22" in any of Pr. 178 to Pr. 189 to assign the function.
Output switches to Low if the orientation stop has made within the orientation
complete width while the start and X22 signals are input.
Orientation complete
For the ORA signal output, set "27 (positive logic)" or "127 (negative logic)" in any of
Pr. 90 to Pr. 196.
Output switches to Low if the orientation not stop has made within the orientation
complete width while the start and X22 signals are input.
Orientation fault
For the ORM signal output, set "28 (positive logic)" or "128 (negative logic)" in any of
Pr. 190 to Pr. 196.

0 Internal stop position command (Pr. 356: 0 to 16383)
