¿Qué significa F107 ?
The control module is unable to recognize the power module it is attached to, indicating a hardware failure or improper assembly after a module change. The drive cannot establish basic communication or identification with its power section, preventing startup.
Causas comunes
- The power module has been physically replaced, and the control module has not been properly initialized to recognize the new power module.
- Data corruption in the control module's non-volatile memory regarding its last known power module ID.
- The control module or power module has experienced an internal hardware failure preventing proper identification during startup.
- Loose or intermittent connection between the control module and the new power module.
- A significant difference in firmware versions or revisions between the control and power modules after a replacement.

3. If available, try installing the original control module (if known good) onto the new power module to rule out control module failure.
- 4
4. Inspect the interconnect pins between the control module and the power module for damage or contamination.
