The Rexroth (and the R22 series) is a powerful motion control unit typically used in Synax200 or VisualMotion systems. Fault codes on this unit are generally categorized into initialization states, hardware errors, and communication faults. Wake Industrial 1. Initialization & Power-On State Errors
Ensure secondary interface communication boards (like PROFIBUS or DeviceNet cards) are seated tightly. 3. Optical Ring (SERCOS) Communication Faults (F01–F08)
Internal errors point directly to the logic board processing components. rexroth ppcr221 fault codes full
The hardware E-stop loop is open. Check safety relays, light curtains, and physical stop buttons across the line.
: For memory faults, execute a complete system power cycle (turn off the 24V control voltage supply, wait 30 seconds, and re-power). For F29, verify user privileges via your HMI or PLC access settings. The Rexroth (and the R22 series) is a
Rexroth fault codes are structured to immediately convey the type and severity of the issue. The PPCR221 controller or its connected drives may display codes with the following prefixes:
