CC amplitude too high %.2s

What does 2940 AC00/E130 mean?

The amplitude of the encoder signal is too high, or a signal indicating contamination is active. This can be caused by electrical disturbance on the motor encoder signal, a short circuit in the motor encoder cable, or the motor encoder itself generating an excessively high signal amplitude.

• The amplitude of the encoder signal is too high or the signal for contamination is active.
• Disturbance on motor encoder signal.
• Short circuit in motor encoder cable.
• Signal amplitude of motor encoder is too high.

Click steps to track your progress.

1. 1

   Inspect the motor encoder cable for the specified axis for any signs of damage, fraying, or short circuits between conductors or to ground.

2. 2

   Verify the ground connection of the motor encoder to ensure proper shielding and signal integrity, reducing external interference.

3. 3

   Check for external sources of electrical interference or noise (e.g., from power cables, welding) that could affect the encoder signal.

4. 4

   Inspect the motor encoder for contamination (e.g., oil, dust, metal particles) or physical damage that might affect signal quality.

5. 5

   If available, use an oscilloscope to measure the encoder signal amplitude directly at the encoder output and at the control input to confirm it is within specified limits.
