Serial Communication Error during Activation

¿Qué significa 749 ?

A serial communication error occurred while the Series 16i system was being activated after power-on. This indicates a problem in the communication link to the spindle amplifier, preventing normal startup.

• A serial communication failure occurred during the boot-up sequence.
• The serial device failed to respond within the expected timeout period.
• Incorrect serial port settings (baud rate, parity, stop bits) during activation.
• A physical connection issue with the serial cable or connector.

1. 1

   Verify the serial cable connection between the controller and the device at terminal RS232-A.

2. 2

   Confirm the serial communication parameters (baud rate, parity) match between the controller and the device.

3. 3

   Measure the voltage levels on the serial communication lines (TXD, RXD).

4. 4

   Attempt to establish a basic serial communication test with the device.
