Encoder battery dead (_ecENCODER_BATTERY_DEAD)

What does 10038 mean?

This information message indicates that the battery backup supply for a Smart Absolute (Smart Abs) encoder has failed. This typically appears during startup or when the drive is enabled. A dead encoder battery means the absolute position information will be lost during power cycles, requiring re-homing or potentially causing incorrect startup positions.

• The internal battery of the Smart Absolute encoder has reached the end of its service life (e.g., typically 5-10 years).
• Prolonged periods of machine downtime or power-off, draining the battery without an opportunity for recharge (if applicable).
• Environmental conditions (e.g., extreme temperatures) reducing battery life prematurely.
• A fault in the encoder's internal charging circuit (if rechargeable) or battery monitoring circuit.

Click steps to track your progress.

1. 1

   Obtain a replacement battery for the specific Smart Absolute encoder model as recommended by the manufacturer.

2. 2

   Power down the drive and machine, then carefully open the encoder's battery compartment (if external) or replace the entire encoder unit if the battery is internal.

3. 3

   Install the new battery, ensuring correct polarity (e.g., + and - terminals).

4. 4

   Power up the drive and verify that the "Encoder battery dead" message is no longer present in the error log (e.g., S6-01 (Encoder Status) indicates healthy).

5. 5

   If absolute position was lost due to the dead battery, perform an absolute position homing routine (e.g., HOME command, P5-01 (Homing Mode)) to re-establish the machine's reference.
