Clear IO Port Alarms

This operation is used to clear IO port alarm before machining, so as to establish a good communication between the control system and servo drive.

Common alarms include the following:

After you fail to clear these alarms, please contact us.

Clear the Alarm of Terminal Board Disconnection

To clear the alarm of terminal board disconnection, check the following:

Wiring related to the terminal board.

If it is not correct and firm, do wiring again.
Port polarities in IO Port window.

If they are not correct, modify the polarity of the corresponding port and restart the software. See Check Port Information for details.
Terminal board.

If it is damaged, replace it.

To clear the E-stop alarm, check E-stop button:

If it is pressed, release the button.
If it is not pressed, modify the polarity of E-stop port in IO Port window and restart the software.

When the machine tool triggers the limit switch, the system will send a positive / negative limit alarm.

To clear the limit alarm, move the machine tool towards the opposite direction of limit switch.

To clear the drive alarm, check the following:

Wiring of the drive.

If it is not connected correctly and securely, do wiring again.
Polarity of Servo Alarm port.

If it is not correct, modify the port polarity of the corresponding port and restart the software.
Parameter Driver Station Address (only for bus configuration).

If it does not match with the actual station address of the servo drive, modify it according to the actual station address and restart the software.

For the bus configuration, alternatively, you can clear common drive alarms by clicking Machine Tool → Clear Servo Alarm.

If the port polarity does not match with the switch of machine tool, an alarm will occur.

To clear the alarm of port polarity error, modify the polarity of corresponding ports in IO Port window and restart the software.
