1. 1

   Verify the specific Class 1 diagnostic error reported by the Bosch Rexroth drive for the specified axis, as error 837 indicates an inability to clear a pre-existing Class 1 fault.

2. 2

   Inspect all motor power cables and feedback cables for the affected axis for damage, proper seating, and secure connections at both the drive and motor ends.

3. 3

   Measure the DC bus voltage and control supply voltage (e.g., 24VDC) at the drive input terminals for the affected axis, verifying they are within specified tolerances.

4. 4

   Verify drive parameters related to the motor, feedback system, and control loop for the affected axis against the original machine documentation.
