Encoder Communications Disconnection Error

Was bedeutet 084A0000 ?

A loss of communication has been detected between the encoder and the Servo Drive. This indicates a physical or electrical interruption in the encoder feedback loop, which can prevent motor control.

• Electrical noise interfering with the encoder cable
• Contact failure of encoder signal lines
• Physical disconnection of the encoder cable
• Power supply undervoltage to the encoder
• Encoder hardware failure

1. 1

   Measure the power supply voltage provided to the encoder at its input terminals.

2. 2

   Verify the integrity of all encoder signal lines by checking continuity and checking for proper termination.

3. 3

   Visually inspect all physical cable connections between the encoder and Servo Drive for disconnection or contact failure.

4. 4

   Verify proper grounding and shielding of the encoder cable to mitigate noise.
