Invalid Encoder Data (Encoder 1)

What does 13.3 mean?

Encoder 1's nameplate data, such as measuring steps, pulses per revolution, or multi-turn counts, is invalid or incorrectly configured. This means the drive cannot accurately calculate position or speed, leading to severe control errors. Persistent invalid data will prevent proper drive function.

• Drive parameters for encoder resolution (e.g., P7-05 pulses/rev) do not match the actual encoder specifications.
• Incorrect multi-turn configuration (e.g., P7-07, P7-08 limits) for an absolute multi-turn encoder.
• Corrupted internal encoder memory (e.g., nameplate data) preventing the drive from reading valid information.
• Parameter settings for the encoder's zero position or offset (P7-09) are out of range or illogical.
• Firmware discrepancy or incompatibility between the encoder and the drive regarding data interpretation.

Click steps to track your progress.

1. 1

   Carefully check and re-enter all encoder-specific parameters (P7-xx series) according to the encoder's technical datasheet.

2. 2

   Verify the pulses per revolution (PPR) or measuring steps parameter (e.g., P7-05) directly from the encoder's nameplate.

3. 3

   For multi-turn encoders, confirm the multi-turn range settings (e.g., P7-07 max, P7-08 min) are within the encoder's capability.

4. 4

   Perform an encoder reset or re-calibration routine (if available via drive parameters, e.g., P7-10).

5. 5

   Check for any diagnostic registers or status words from the encoder (if accessible) that might indicate internal data corruption.
