Pulsecoder Serial Data Start/Stop Bit Error

What does SRVO-070 mean?

The start and stop bits of the serial data received from the Pulsecoder are abnormal. This indicates a communication framing error, often pointing to issues with data transmission integrity, such as signal distortion or timing discrepancies.

• Improper start or stop bit framing in the pulsecoder serial data stream.
• Pulsecoder sending data asynchronously or with incorrect timing.
• Noise or signal degradation affecting the integrity of start/stop bits.
• Faulty pulsecoder unit failing to generate correct serial framing.
• Servo controller expecting a different serial data format.

1. 1

   Ensure the robot connection cable (RMP1, RP1) connector (CRF8) on the 6-Axis servo amplifier and the connector on the motor side are tightly connected.

2. 2

   Check that the shielding of the robot connection cable (RMP1, RP1) is securely grounded in the cabinet.

3. 3

   Replace the Pulsecoder.

4. 4

   Replace the servo amplifier.

5. 5

   Replace the robot connection cable (RMP1, RP1, RM1).

6. 6

   Replace the internal cable of the robot (for the Pulsecoder, or for the Motor).
