Reliance Electric UVZC3202 VZ3000 Series 2.2kW Digital AC Servo Drive
Overview
The UVZC3202 (also designated EXIC2-2.2) is a compact, high-performance 2.2kW digital AC servo drive from Reliance Electric’s VZ3000 series, designed for precision motion control in light-to-medium industrial automation applications. As an integrated inverter unit, it combines a bus unit, regulator unit, IGBT power unit, and peripheral circuits into a single rugged chassis, delivering reliable variable frequency and servo control for 3-phase AC motors. Engineered for continuous operation in demanding environments, it serves as a cost-effective solution for new system builds, equipment retrofitting, and replacement of legacy VZ3000 series drives.
Key Features
This servo drive adopts full digital vector control and advanced IGBT sinusoidal PWM modulation, ensuring precise speed, torque, and position regulation with fast dynamic response to load variations. Its compact chassis design (120mm wide × 430mm tall × 270mm deep, approximately 7kg) enables space-saving vertical installation in standard industrial cabinets, while a detachable front cover provides easy access to internal components for maintenance and troubleshooting. Built-in comprehensive protection includes overvoltage, undervoltage, overcurrent, short circuit (5kA system rating), overtemperature, and motor overload safeguards, protecting the drive and connected motors from fault damage. Equipped with an RS-485 Modbus RTU communication interface, it supports seamless connectivity with PLCs, HMIs, and SCADA systems for real-time monitoring, parameter configuration, and remote control. The IP20 (or optional IP21) protection rating and reinforced electromagnetic shielding ensure reliable operation in harsh factory environments with electrical noise, vibration, and moderate dust exposure.

Typical Applications
The UVZC3202 is ideal for light-to-medium industrial motion control applications requiring precision and reliability. It is widely used in small CNC machine tools (spindle and servo axis drives), conveyor systems, packaging machinery, textile equipment, pumps and fans, and general automation machinery. It also serves as a direct replacement for aging or faulty UVZC3202 units in existing VZ3000 series installations, minimizing production downtime and extending the service life of legacy systems.
Compatibility and Availability
The UVZC3202 is fully compatible with the entire VZ3000 series ecosystem, including other inverter units, bus modules, braking units, and AC servo motors. It follows standard VZ3000 series wiring and communication protocols, enabling seamless integration and interchangeability with other series components. Original mass production of this model has been discontinued by Reliance Electric, but new old stock (NOS) and professionally refurbished units are available from authorized industrial automation suppliers. Refurbished drives undergo complete disassembly, component testing, aging, and performance calibration to meet original factory specifications, with standard warranty coverage provided.
