Pulsecoder Serial Data CRC Error

Hva betyr SRVO-069 ?

The serial data transmitted from the Pulsecoder was disturbed during communication, resulting in a Cyclic Redundancy Check (CRC) error. This indicates data corruption, which can be caused by electrical noise, poor shielding, or faulty communication components.

• Corrupted data packets transmitted over the pulsecoder serial interface.
• Faulty pulsecoder generating incorrect checksum values.
• Noise or interference corrupting the cyclic redundancy check (CRC) bits.
• Loose or damaged serial communication cables (e.g., P1-31, P1-32).
• Servo controller not correctly interpreting CRC data from the pulsecoder.

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).
