Reliance Electric Vectrive AC Servo Vector Drive Series
Overview
Vectrive is a high‑performance AC servo vector drive series originally designed and manufactured by Reliance Electric (later acquired by ABB). Engineered for precision motion control in demanding industrial environments, the Vectrive series delivers accurate speed, torque, and position regulation for AC servo and induction motors. It is widely deployed in CNC machine tools, automated assembly lines, packaging machinery, material handling systems, and process industries requiring stable dynamic performance. The entire Vectrive lineup has been discontinued by the original manufacturer and is now available as refurbished, surplus, or used units for legacy system maintenance, replacement, and upgrades.
Series Composition
The Vectrive series consists of multiple models tailored to different power and performance requirements, with the VCIB prefix being the most common:
VCIB‑07: 7A continuous, 14A peak, 2.2–3.7kW
VCIB‑11: 11A continuous, 22A peak, 3.7–5.5kW
VCIB‑16A: 16A continuous, 32A peak, 5.5–7.5kW
VCIB‑33: 33A continuous, 66A peak, 7.5–15kW
VCIB‑85A/140: High‑power models up to 140A for heavy‑duty applications
VC‑211B/215B: Front‑mounted LCD display and operator interface accessories for Vectrive‑C drives
Key Features
Vectrive drives integrate advanced vector control technology and robust modular hardware, offering exceptional performance and durability for industrial use. They employ high‑precision field‑oriented vector control algorithms that provide fast dynamic response, smooth low‑speed operation, and accurate torque regulation across the entire speed range, reducing mechanical stress and improving energy efficiency. All models support three primary control modes—speed, torque, and position—ensuring flexibility for diverse motion control tasks.
Standard equipment includes an RS‑485 Modbus RTU communication interface for seamless integration into industrial control systems, enabling remote configuration, monitoring, and data exchange. The hardware architecture features a combined converter‑inverter module, pre‑charge circuit, regenerative resistor unit, relay module, and integrated cooling fan, ensuring reliable power conversion and safe operation under regenerative conditions.
Configuration and diagnostics are simplified via the onboard keypad or Zterm, a Windows‑based software tool for parameter setup, auto‑tuning, and fault analysis. Housed in a rugged gray metal enclosure with IP20 protection, Vectrive drives resist dust, vibration, and electrical noise, ensuring stable operation in harsh factory environments. Comprehensive built‑in protection functions safeguard the drive and motor against overvoltage, undervoltage, overcurrent, short circuit, overtemperature, and overload conditions, minimizing downtime.
