APC ALARM: FRAMING ERROR

What does SV0303 mean?

A framing error occurred in the data transfer from the absolute-position detector, preventing the system from obtaining the correct machine position. This problem is indicative of a defect in the absolute-position detector, its cable, or the servo interface module.

• Incorrect data framing from the APC encoder.
• Data bit corruption during transmission.
• Faulty APC encoder sending malformed data packets.
• Interference on communication lines causing bit errors.

Click steps to track your progress.

1. 1

   Inspect APC encoder output for framing errors using an oscilloscope.

2. 2

   Ensure correct data format (e.g., start bits, stop bits) is configured.

3. 3

   Test APC encoder signal integrity for noise or distortion.

4. 4

   Check APC encoder firmware for updates.
