Description
Product Overview
The Bosch Rexroth PPC-R22.1N-T-Q2-G2-NN-FW is a programmable motion and logic controller from the PPC family, designed for machine automation requiring coordinated motion control and communication with compatible drive systems. Its RECO-format hardware is intended for installation in a compatible rack rather than as a standalone DIN-rail PLC. The controller combines machine-control processing with communication and expansion capabilities. The integrated Ethernet interface supports communication with the wider automation environment, while its configured expansion hardware provides additional interfaces for machine-specific control requirements. The corresponding material number is R911170778.
The type code identifies several important configuration details. The PPC-R22.1N base designation identifies the controller platform, while T denotes the onboard Ethernet interface. G2 identifies the LAG master encoder interface configuration. The NN position indicates that no additional option is fitted in that designated expansion position. The Q2 designation appears in the complete part number, but the available VisualMotion 11 type-code documentation does not establish its exact meaning in this combination. It should therefore be verified against the original order configuration or the hardware identification labels rather than automatically described as a DAQ03 module. The FW suffix indicates that firmware is handled as a separate configuration item.
For maintenance engineers, the PPC-R22.1N-T-Q2-G2-NN-FW requires a complete hardware and software compatibility check before replacement. The controller’s 24 VDC supply, rack mounting, expansion-card configuration, encoder interface, and firmware package all affect commissioning. A replacement with a similar PPC-R22.1 type code may have a different expansion arrangement or firmware configuration. Confirm the installed drive family, VisualMotion software version, firmware image, parameter backup, and encoder wiring before exchanging the unit. A controller that powers up successfully is not necessarily ready to resume synchronized machine operation.
Product Introduction
When a multi-axis machine stops because of a controller fault, replacing the main control unit is only one part of the recovery process. The expansion-card arrangement, encoder feedback connections, firmware image, and drive communication configuration must also match the original installation.
The Bosch Rexroth PPC-R22.1N-T-Q2-G2-NN-FW is a RECO-format VisualMotion controller with onboard Ethernet and a G2 master encoder interface configuration. Its Q2 option and firmware package should be verified from the original machine documentation before procurement.

Frequently Asked Questions
Q1: What is the primary function of the .1N-T-Q2-G2-NN-FW?
It is a programmable multi-axis motion and logic controller used in industrial machinery. It coordinates machine-control functions and communicates with compatible drive and automation equipment through its configured interfaces.
Q2: What does the G2 designation mean?
The G2 type-code designation identifies the LAG master encoder interface configuration. This interface is relevant to master encoder feedback applications. Confirm the installed card and encoder wiring before replacing the controller.
Q3: What does the T designation mean?
T identifies the onboard Ethernet interface in the .1 type-code documentation. Ethernet availability does not establish that every higher-level industrial protocol is enabled; protocol support depends on the controller firmware and application configuration.
Q4: What does the FW suffix mean?
FW indicates that firmware is handled as a separate order or configuration item. Do not assume that a replacement controller includes the same firmware version or machine-specific application. Verify the firmware package and retain a backup of the original control configuration.
Q5: Can I hot-swap the .1N-T-Q2-G2-NN-FW?
Do not assume hot-swap capability. Removing the controller can interrupt coordinated machine operation and may affect connected drives and feedback interfaces. Follow the machine shutdown procedure and the applicable Rexroth installation instructions.
Q6: Does this controller support firmware v3.1?
The model number alone does not establish compatibility with firmware v3.1. Check the installed VisualMotion software release, firmware package, expansion-card configuration, and connected drive family. Firmware should be matched to the actual controller hardware and application.
Q7: What should be checked before purchasing a replacement?
Verify material number R911170778, the complete type code, hardware revision, Q2 and G2 option configuration, Ethernet interface, and firmware requirements. Request photographs of the nameplate and expansion-card positions. For refurbished units, ask for a power-up test, diagnostic status, interface checks, and confirmation that the firmware configuration is known.
Procurement and Maintenance Considerations
The .1N-T-Q2-G2-NN-FW should be sourced as a configured motion-control assembly, not simply as a generic .1 controller. A mismatch in encoder interface hardware or firmware can prevent a replacement from operating correctly even when the unit fits the rack and accepts 24 VDC power.
Before approving a replacement, confirm:
- Material number R911170778 and complete type code.
- Q2 option identification from the original machine records.
- G2 LAG encoder interface configuration.
- Compatible RECO rack and vertical mounting arrangement.
- Firmware package and VisualMotion software version.
- Existing parameter and application backups.
- Drive communication and encoder feedback wiring.
For used or refurbished stock, request revision photographs, diagnostic records, and evidence of functional testing. A basic power-on test is insufficient for a controller responsible for coordinated multi-axis motion.
