Quin Systems has extended their range of compact low-cost drives to include 2 new 100-230V 3-phase drives for motors with continuous ratings of 6A and 9A. These new drives complement the existing 100-230V AC single-phase 4A version and provide full intelligent functionality to more powerful applications.

Measuring 74mm wide, 210mm deep and just 220mm high, the Mini QDrive is not only compact, it is also low-priced. As with the rest of the QDrive family, the new intelligent drives combine an advanced DSP digital servo drive with a powerful Quin Programmable Transmission System (PTS) motion controller. The digital signal processor chip delivers high bandwidth closed-loop performance, whilst a second processor provides full motion and logic control with analogue and digital I/O.

QDrives can be used with virtually any make of AC brushless servo motor, and are also configurable for use with AC induction motors having full flux vector control. Resolver feedback comes as standard with many different encoder feedback options available such as Hiperface (SinCos).

A CANbus interface provides full synchronisation between the Mini QDrive and other QDrives or compatible modules - either in a peer-to-peer configuration (Synchrolink) or via SERVOnet, using the QManager. The QManager can be used to manage the programming, co-ordination and diagnostics of SERVOnet networks, and to serve as a gateway to Fieldbus and fast Ethernet networks. The Mini QDrive has onboard digital and analogue I/O, two serial ports, and a Modbus interface option.

Set up and tuning is via the PTS software suite, which features powerful Windows-based tools for diagnostics, motion generation, configuration and graphical tuning. Its large library of standard machine functions includes registration, tension, gearing, cams and even more complex algorithms.

The built-in PTS Scope software gives users comprehensive machine diagnostics such as current and velocity loops, and even drive temperature. What is more, the scope can be operated via an Internet connection, enabling machines to be supported anywhere in the world.
