Notifying that the motor is ready: READY output
When the motor becomes ready, the READY output will turn ON. Confirm that the READY output is ON
before inputting pulses. The READY output remains ON while pulses are input.
The READY output is OFF under the following conditions. Motor operation is disabled while the READY
output is OFF:
• The main power supply is cut off.
• An alarm is present.
• The S-ON input is OFF (the S-ON input logic is “Contact A (normally open)” )
• The FREE input or CLR input is ON.
• An operation is performed on the OPX-2A in the test mode or copy mode.
• A test operation is performed using MEXE02.

Notifying that operation is in progress: MOVE output
The MOVE output can be enabled by selecting the output using the application parameter for output signal
selection 1 [APP-1-02].
The MOVE output remains ON while the motor is operating. You can set the minimum time during which the
MOVE output remains ON using the application parameter for minimum ON time for MOVE signal
[APP-1-08]. Even in a short operation, the MOVE output will remain ON for the time set in this parameter.
Example: When 10 ms is set in the parameter for minimum ON time for MOVE signal
[APP-1-08]

Notifying the completion of operation: END output
Once the motor operation ends and the position deviation falls within the positioning complete output band,
the END output will turn ON. How long it takes for the END output to turn ON after the operation command
completes varies depending on the operating conditions, etc.
You can set the band within which the END output turns ON, using the application parameter for positioning
complete output band [APP-1-04].

Notifying that the positioning target is near: NEAR output
The NEAR output can be enabled by selecting the output using the application parameter for output signal
selection 2 [APP-1-03].
Once the motor operation ends and the position deviation falls within the positioning near output band, the
NEAR output will turn ON.
You can set the band within which the NEAR output turns ON, using the application parameter for
positioning near output band [APP-1-05].
If the positioning near output band parameter [APP-1-05] is set to a value greater than the value in the
positioning complete output band parameter [APP-1-04], the NEAR output will turn ON before the END
output does. This way, you can be informed that the positioning target is near.
