No Absolute Encoder Present

What does 250 mean?

This fault is triggered when the DDS 2.1 drive attempts to execute the procedure command 'Set Absolute Measuring' (IDN P-O-0012) but does not detect an absolute encoder on the connected motor. This indicates a mismatch between the commanded function and the motor's feedback device.

• The connected motor does not have an absolute encoder.
• Absolute encoder is not properly connected or is defective.
• Incorrect drive configuration for absolute encoder operation.

Click steps to track your progress.

1. 1

   Verify that the motor being used is equipped with an absolute encoder as required for the 'Set Absolute Measuring' command (IDN P-O-0012).

2. 2

   Inspect the absolute encoder's wiring and connections to the DDS 2.1 drive for proper installation and integrity.

3. 3

   Check the drive's parameters related to feedback configuration to ensure it is correctly set for an absolute encoder.

4. 4

   If an absolute encoder is required, exchange the motor with one that has a properly functioning absolute feedback device mounted.
