System error

What does F13.15 mean?

The encoder evaluation system is signaling a critical system error for Encoder 1, possibly due to a multi-turn encoder being outside its configured track area, incorrect limits, or faulty numerator/denominator factors. This indicates a severe issue with position calculation or encoder setup, risking incorrect positioning and drive instability.

• Absolute multi-turn encoder has exceeded its maximum configured track area or internal counter limits.
• Incorrectly configured scaling parameters (e.g., P7-05 numerator, P7-06 denominator) leading to internal calculation errors.
• Mismatch between the physical encoder's multi-turn range and the software configuration in the drive.
• Internal defect within the encoder evaluation circuitry of the drive or the encoder itself.
• Encoder's internal battery (if applicable for multi-turn) is low or disconnected, causing loss of multi-turn position.

Click steps to track your progress.

1. 1

   Verify the configured multi-turn limits (e.g., P7-07, P7-08) against the encoder's specified multi-turn range.

2. 2

   Inspect the encoder's battery (if multi-turn) for proper connection and measure its voltage (e.g., 3.6VDC).

3. 3

   Confirm the numerator (P7-05) and denominator (P7-06) scaling parameters match the encoder's resolution and application requirements.

4. 4

   Check the encoder's internal diagnostic register (if accessible via communication, e.g., using SDO access) for specific error codes.

5. 5

   Attempt to re-initialize the encoder's multi-turn counter (refer to drive/encoder manual for specific procedure).
