1. 1

   Perform a complete power cycle of the drive system (main power off/on) to clear any transient boot issues.

2. 2

   Check the connections between the control unit and the power unit (e.g., Drive-Cliq cable) for secure fit and damage.

3. 3

   Attempt a firmware update for the power unit using a valid firmware image (e.g., via SD card or engineering software).

4. 4

   Record the fault value displayed in parameter r0949 for reference when contacting technical support.

5. 5

   If possible, swap the power unit with a known good, compatible unit to rule out a hardware defect in the power unit itself.
