Absolute enc. monitoring, measuring encoder (encoder alarm)

Hva betyr E2079 ?

An alarm condition has been detected by the IndraDrive MPx02 from the absolute measuring encoder (often a linear scale or external rotary encoder directly monitoring the load). This indicates a problem with the primary absolute position feedback for the machine's actual position, impacting precision, homing, and safety functions.

• Loss of absolute position data from the measuring encoder (e.g., battery failure, memory corruption).
• Internal fault within the absolute measuring encoder itself.
• Communication error between the drive and the absolute measuring encoder.
• Incorrect measuring encoder parameterization in the drive for the specific encoder type or resolution.
• Mechanical damage or misalignment of the measuring encoder relative to the axis.

1. 1

   Check the absolute measuring encoder's status indicators (LEDs) for any error codes or abnormal behavior according to its manual.

2. 2

   Verify the communication wiring and protocol settings between the IndraDrive MPx02 and the absolute measuring encoder, ensuring robust connection.

3. 3

   If the measuring encoder uses a battery for absolute position retention (e.g., multi-turn rotary), check its voltage and replace it if necessary.

4. 4

   Ensure that the absolute measuring encoder parameters in the drive are correctly configured for the specific encoder type, resolution, and mounting orientation.

5. 5

   Attempt a re-initialization of the absolute position or a reference run if the absolute position data has been lost, and if the alarm persists, consider replacing the absolute measuring encoder.
