Bosch Rexroth PHG GG 1 – Handheld Teach Pendant | CL 500 / IndraControl Platform
When a CNC machine tool or automated assembly line loses its programming interface, production does not simply pause — it stops entirely. Operators cannot jog axes, verify positions, or upload new motion sequences without a functioning teach pendant. The Bosch Rexroth PHG GG 1 is the dedicated handheld programming terminal engineered for the CL 500 and IndraControl control families, restoring full operator-level access to motion parameters, I/O diagnostics, and program management directly at the machine.
Within the Rexroth CL 500 ecosystem, the PHG GG 1 occupies the role of the primary human-machine interface for field-level commissioning and maintenance. Its ergonomic handheld form factor, combined with direct serial communication to the CL 500 rack, makes it the preferred tool for machine builders and end-user maintenance teams across automotive, machine tool, and general manufacturing sectors worldwide.

- Proven field reliability: Designed to withstand industrial floor environments including vibration, dust, and temperature variation.
System Architecture & Signal Flow
The PHG GG 1 connects to the CL 500 controller via a dedicated serial port on the rack. Communication is handled through the Rexroth proprietary protocol, allowing the pendant to read and write motion parameters, monitor real-time I/O states, and execute jog commands. The signal flow is: PHG GG 1 → Serial Cable → CL 500 Rack CPU Module → Drive Amplifiers → Servo Axes. No additional gateway or protocol converter is required for standard CL 500 installations.
Compatible system components include the CL 500 CPU modules, RACK-GG 500 backplane, and associated Rexroth servo drive amplifiers. For multi-axis systems, the pendant provides sequential axis selection to manage all drives from a single handheld unit.

Technical FAQ
Q: Is the PHG GG 1 compatible with IndraControl platforms beyond the CL 500?
A: The PHG GG 1 is primarily designed for the CL 500 series. Compatibility with other IndraControl variants depends on the specific controller generation and communication port configuration. Please contact our team with your controller model for confirmation.
Q: Can the PHG GG 1 be used as a permanent HMI, or only for commissioning?
A: It is designed as a portable commissioning and maintenance tool. For permanent operator interfaces, Rexroth offers dedicated panel-mount HMI solutions. The PHG GG 1 is typically connected only during setup, diagnostics, or program changes.
Q: What cable is required to connect the PHG GG 1 to the CL 500 rack?
A: A Rexroth-specified serial cable is required. If you need the cable part number or a compatible cable sourced alongside the pendant, please include this in your inquiry.
Q: Do you provide a warranty on surplus PHG GG 1 units?
A: Yes. Konmask.com provides a standard 90-day tested-functionality warranty on all verified surplus units. Extended warranty options are available upon request.
Q: Can you ship the PHG GG 1 internationally?
A: Yes. We ship globally with DHL, FedEx, and UPS express services. Export documentation and commercial invoices are provided for customs clearance.
