Core Advantages

1. Direct Replacement for Legacy MASTERDRIVES Systems

The CUVC module is the central control board for SIMOVERT MASTERDRIVES vector control units. For facilities operating these proven drive systems, the CUVC provides a direct board-level replacement solution, avoiding the cost and complexity of full drive replacement . This is particularly valuable for installations where the drive mechanics and power section remain fully functional.

2. Advanced Vector Control Capability

The CUVC module implements Siemens' proven vector control algorithms in firmware version V3.4. This enables precise speed and torque regulation for demanding applications including pumps, fans, extruders, and process machinery . Both closed-loop (with encoder feedback) and open-loop (sensorless) control modes are supported .

3. Comprehensive Integrated I/O

The module includes a full complement of on-board I/O: 7 digital inputs/outputs, 2 analog inputs, and 2 analog outputs. This eliminates the need for additional I/O expansion cards in many applications, simplifying system design and reducing cost .

4. Proven Reliability in Critical Applications

The SIMOVERT MASTERDRIVES platform has been deployed for decades in critical industrial applications including water treatment, metals processing, pulp and paper, and heavy manufacturing. The CUVC module is engineered for continuous operation in these demanding environments .

5. Active Service Support

Despite the product being discontinued, Siemens continues to offer spare part delivery, repair, and exchange services for the CUVC module . This ensures that existing MASTERDRIVES installations can be maintained for years to come.
