Description
Product Introduction
Rexroth PPC-R22.1N-T-Q2-G2-NN-FW is a PPC Series CNC control unit designed for industrial motion systems, machine tools, and synchronized servo applications. The controller combines PLC processing and motion coordination functions within the Rexroth RECO rack platform.
This unit operates from a 24 V DC supply and supports industrial communication integration with Rexroth drive systems and fieldbus architectures. For retrofit projects, retaining the original PPC hardware often reduces commissioning time and avoids rewriting legacy machine logic. Verify existing firmware revisions and fieldbus settings before replacement.
Frequently Asked Questions
Q: Can this controller be hot-swapped during machine operation?
A: Honestly, do not attempt live replacementunless the machine builder specifically documents that procedure. Most PPC rack systems require full shutdown before removing the module. Pulling the controller under power can interrupt bus communication and damage the rack interface circuitry.
Q: Is this controller obsolete? What replaces it?
A: Yes, the PPC platform is considered legacy hardware in many factories. Rexroth migration paths usually involve IndraControl systems, but compatibility depends heavily on existing drive firmware and machine software structure. The most common mistake is replacing only the controller while ignoring old SERCOS or PROFIBUS device revisions.
Q: Will replacing the unit erase the machine program?
A: It can if no backup exists. Before removing the old hardware, back up PLC projects, NC parameters, drive settings, and any compact flash data. Also record firmware revisions and photograph every DIP switch and jumper position. That step prevents many commissioning delays during startup.
Q: Are these controllers refurbished or unused surplus stock?
A: These are New Original surplus units sourced from unused OEM inventory, canceled automation projects, and warehouse spare stock. They are not repaired boards. Every module undergoes serial verification, anti-counterfeit inspection, and detailed visual inspection before testing.
