Notifying that the motor is ready: READY output
When the motor becomes ready, the READY output will turn ON. Start the operation after confirming that the
READY output has turned ON. The READY output remains OFF while the motor is operating.
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),” and the operation after
stopping is “Servo lock”).
• The FREE input, CW input or CCW input is ON.
• The BRAKE input is OFF (the BRAKE input logic is “Contact B (normally closed)”).
• 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 timing of electromagnetic brake control: MBC output
Use the MBC output to control the electromagnetic brake using a programmable controller, etc.
The MBC output can be enabled by selecting the output using the application parameter for output signal
selection 1 [APP-1-02].
The MBC output will turn ON when the electromagnetic brake is released, and turn OFF when the
electromagnetic brake is actuated (= to hold the load in position). Set the programmable controller to control
the electromagnetic brake by detecting the ON/OFF status of the MBC output.

Notifying that the detected speed has become zero: ZV output
The ZV output can be enabled by selecting the output using the application parameter for output signal
selection 2 [APP-1-03]. When the detected speed drops into the zero speed output band, the ZV output will
turn ON.
You can set the band within which the ZV output turns ON, using the application parameter for zero speed
output band [APP-1-06].
