Variable Speed Drive Unidrive M200 has been designed for applications that require flexible integration with systems via modern network and fieldbus communications and high performance RFC-A (Rotor Flux Control) open-loop motor control. The Unidrive M201 variant includes a keypad mounted potentiometer.

The Unidrive M200/M201 is available in nine frame sizes, covering all low voltage ranges, and provides up to 200 hp. This versatile drive has several cost and space saving features, such as “snap-in” expandable I/O or communication options and onboard PLC (Unidrive M200 only) using IEC-61131-3 compliant programming software.

Unidrive M200 has been designed for applications that require flexible integration with systems via industrial Ethernet protocols and fieldbuses together with advanced open loop motor Rotor Flux Control (RFC-A).

The Unidrive M200 provides the most convenient upgrade path for Commander SK users.

  • Features

    • Unidrive M200's SI interface module enables integration with a wide range of available industry standard communications or extended I/O such as EtherNet/IP, Modbus TCP/IP, EtherCAT, PROFINET, DeviceNet, PROFIBUS, CANopen
    • AI-485 Adaptor option permits connection to RS485 adaptor option permits connection to RS485 networks using Modbus RTU

    Reduced system costs by directly integrating with applications
    • Unidrive M200 incorporates an onboard PLC which can execute Machine Control Studio (IEC61131-3) programs for logic and sequencing with real-time tasks - removing the need for additional PLC's

    Improve throughput with advanced open-loop motor control algorithms
    • Rotor Flux Control (RFC-A) gives maximum stability and control of induction motors at all powers
    • 180% motor overload suitable for heavy industrial machinery applications

    Install and configure quickly and easily
    • Easy-to-use fixed LED keypad
    • Useful parameter guide located on the front of the drive
    • Use Unidrive M Connect PC tool or SD card with AI-Backup Adaptor to clone and transfer parameter sets
    • Din rail mounting is supported below 2 hp (1.5 kW)

    Minimize downtime with robust and reliable drives
    • Conformal coated PCBs – for increased resilience to moisture, dust, chemicals and temperature extremes. 
    • Patented air flow system – efficiently cools while protecting internal components. 
    • Ingress protection up to IP21 – UL open class (NEMA 1) compliant.

    Save energy 
    • Low power standby mode – drives can sit idle for significant periods. 
    • Automatic 3-speed cooling fan –intelligently responds to load. 
    • Square law V/F mode - optimized for quadratic loads like pumps and fans. 
    • Dynamic V/F mode - keeps energy usage and motor losses to a minimum. 
    • Unidrive M is 98% efficient – only 2% energy is lost in the conversion process across the drive.
