Encoder Error

What does 7301 mean?

A communication fault exists between the pulse encoder and its interface module, or between the interface module and the drive itself. This prevents accurate speed and position feedback, potentially causing control instability or incorrect motor operation.

• Encoder internal fault or failure.
• Loss of communication signal from the encoder.
• Encoder power supply issue (check P0-09).
• Encoder resolution mismatch or incorrect model selected.

Click steps to track your progress.

1. 1

   Inspect the pulse encoder unit and its wiring for damage, loose connections, or shielding issues.

2. 2

   Inspect the pulse encoder interface module and its wiring for damage, loose connections, or proper installation.

3. 3

   Check parameter group 50 (ENCODER MODULE) settings to ensure correct encoder configuration.
