Resetting the roll diameter: W-RESET input
In high function mode I and high function mode II, the current winding (unwinding) diameter is calculated.
If the W-RESET is turned ON while the motor is stopped, the winding (unwinding) diameter will be reset to
the initial diameter at the ON edge of the W-RESET input.
Nothing will happen if the W-RESET input is turned ON while the motor is operating.

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 FREE input, CW input or CCW 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 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 speed is being limited: VLC output
When the detected speed reaches the speed limit, the VLC output will turn ON.
