If you are dealing with a specific fault code not listed above, or need help with a particular step, tell me your card is showing, the valve model it controls, and what the machine was doing when it failed. I can tailor a custom solution for your exact situation. Share public link
: This is the most frequent code and serves as a general "Drive Fault" indicator. It means at least one connected drive has encountered a fatal error. : You must use diagnostic software like

The internal power transistors (MOSFETs) inside the PPCR221 have exceeded safe thermal limits. It means at least one connected drive has
These often occur due to data corruption or power issues affecting the controller's memory. Loss of parameters on the CF card.
(often referred to in field maintenance as the PPCR221) is a powerful, compact multi-axis motion and PLC controller engineered by Bosch Rexroth. It typically operates within complex automation networks, utilizing a SERCOS fiber-optic interface to coordinate multiple digital servo drives synchronously.
Remedy : Ensure encoder cables run separated from motor high-voltage power lines to isolate noise. Replace the motor/encoder cable if shielding continuity is lost. 5. Structural Overview of Drive-Level Response States
