E2054

Not homed

Bosch Rexroth · IndraDrive C Drive Controllers

What does E2054 mean?

The axis has not been referenced or 'homed' since power-up or a previous reset. This prevents accurate absolute positioning and certain motion commands.

Common Causes

  • Homing procedure has not been performed after drive power-on or reset.
  • Homing switch or sensor malfunction preventing successful homing.
  • Loss of encoder absolute position reference (e.g., due to battery loss for multi-turn encoders).
  • Incorrect homing parameters or sequence configured in the drive controller.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Initiate the homing procedure for the axis according to the machine's operational manual.

  2. 2

    Verify the functionality of the homing switch or sensor and its wiring to the drive's inputs.

  3. 3

    Check the battery status for absolute encoders, if applicable, and replace if low or depleted.

  4. 4

    Review homing parameters (e.g., homing offset, homing speed, homing direction) in the drive configuration and ensure they are correct for the application.
