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
Initiate the homing procedure for the axis according to the machine's operational manual.
- 2
Verify the functionality of the homing switch or sensor and its wiring to the drive's inputs.
- 3
Check the battery status for absolute encoders, if applicable, and replace if low or depleted.
- 4
Review homing parameters (e.g., homing offset, homing speed, homing direction) in the drive configuration and ensure they are correct for the application.
