Technical Specifications

Solving the Discontinued Hardware Crisis

The Rexroth TS 2plus and VarioFlow conveyor platforms were installed across thousands of automotive, electronics, and consumer goods plants throughout the 1990s and 2000s. Many of those lines remain in production today, carrying throughput targets that were set long before any decommissioning budget was approved. The MTR UE41PP motor-positioner unit is the drive heart of individual conveyor stations on these platforms. It controls pallet indexing, stop-and-go sequencing, and load transfer between sections.

When this unit fails, the conveyor station stops. A single failed station can halt an entire line segment. The engineering path to replace it with a current-generation motor requires new mounting brackets, revised cable routing, updated PLC I/O mapping, and re-commissioning of the positioner logic — work that takes days, not hours, and requires Rexroth-certified engineers who are increasingly difficult to retain for legacy platform work.

Condition & Reliability Assurance

Discontinued parts sourced from secondary markets carry real risk. DriveKNMS applies a 5-step inspection protocol before any unit ships:

• Step 1 – Electrolytic Capacitor Assessment: All capacitors in the motor control circuit are tested for capacitance drift and ESR. Units showing degradation beyond OEM tolerance are rejected. Capacitor aging is the primary failure mode in stored motor electronics.
• Step 2 – Firmware Version Verification: Where applicable, the positioner module firmware is confirmed against the known compatible version matrix for the TS 2plus platform. Mismatched firmware causes indexing errors that are difficult to diagnose in the field.
• Step 3 – Pin and Connector Corrosion Inspection: All connector pins (Z506A, 923-600-G7, 923-601-G4) are inspected under magnification for oxidation, fretting corrosion, and mechanical deformation. Corroded pins are the leading cause of intermittent faults on legacy conveyor drives.
• Step 4 – Insulation Resistance Test: Motor windings are tested for insulation integrity. Units with degraded winding insulation are not offered for sale.
• Step 5 – Functional Run Test: Where test equipment permits, units are powered and run at rated conditions before packaging.

Key Features for System Maintenance

How do I confirm the unit is genuine and not a counterfeit?
All Rexroth units sourced by DriveKNMS are verified against Bosch Rexroth's part marking standards, including label format, serial number structure, and housing casting marks. Inspection photos are available on request before purchase.
