Emerson VFD Drives Unidrive M200 industrial series

Emerson frequency inverter Unidrive M200 series integration through flexible communications.

Integrate Unidrive M200 into any system.
Unidrive M200 has been designed for applications that require flexible integration with systems via modern communication networks and fieldbuses, or through advanced Rotor Flux Control (RFC-A) open-loop motor control. The M200 provides the most convenient upgrade path for Commander SK users. The ‘SI’ Interface in M200 enables integration with a wide range of available industry standard fieldbuses or extended I/O to allow remote control and diagnostics across different networks. These include SI-Ethernet, SI-EtherCAT, SI-PROFINET, SI-PROFIBUS, SI-CANopen and SI-DeviceNet. Additionally, the AI-485 Adaptor option permits connection to RS485 networks using Modbus RTU.

Maximize productivity with performance open-loop motor control.
M200’s advanced Rotor Flux Control (RFC-A) utilizes closed-loop current control to give maximum stability of induction motors at all powers. It provides a high bandwidth control algorithm with 125 μs current loop update rates and 180 % motor overload for heavy industrial machinery applications.

Install and configure quickly and easily.
Unidrive M200 has an easy-to-use fixed LED keypad as standard and a useful parameter guide on the front of the drive to enhance understanding when setting up and interrogating. Parameter sets can be easily saved or transferred between drives using the Unidrive M Connect PC tool or an SD card with AI-Back-up or AI-Smart Adaptor. An easy-fit remote LCD keypad is available for IP66 panel mounting and extra diagnostic information. Additionally, a remote real time clock keypad, Remote Keypad RTC, is also available (meets IP54/NEMA 12). Fast install DIN rail mounting is supported up to 1.5 kW (2 hp).*

Transfer parameters without mains power.
For fast, serial machine production, the AI-Back-up or AI-Smart Adaptor option can be powered by 24 V to transfer parameter sets to and from standard SD Cards.

Minimize downtime with robust and reliable design.
Unidrive M200 is extremely reliable due to a design based on over 40 years of drive knowledge, expertise and development. Build quality is ensured using world leading manufacturing processes. M200 is packed with features proven to keep systems running in environments as described by IEC60721-3-3 3C3 and EN60068-2- 60 Meth. 4. 
- PCBs have conformal coating to further increase resilience to harsh environmental conditions 
- A patented air flow system cools the drive more effectively and protects internal components
- Wide supply voltage tolerance keeps drive operation smooth in areas where supplies are variable 
- Intelligent 3 speed user-replaceable cooling fan with patented fan-fail detection circuit 
- Trip avoidance features take intelligent action instead of tripping out critical processes. For example:  Load Shedding reduces speed at current limits, supply loss ride-through keeps running during brown outs 
- Derating values are available so that M200 can be run in higher temperature environments 
- High overload capability - 180 % for 3 s or 150 % for 60 s 
- Ingress protection up to IP21- UL open class (NEMA 1) compliance

Reduce application size and cost.
Unidrive M200’s compact drive dimensions are among the smallest in class at every power rating.

Easily upgrade Commander SK designs and installations.
Unidrive M200 is designed for easy migration from Commander SK. Tools are available for fast and easy installation: 
- Compatible dimensions, along with retrofit kits, mean that M200 can easily fit in existing Commander SK applications using existing fittings • Same power and control wiring philosophy 
- Parameter porting from Commander SK to Unidrive M200 is supported by the Unidrive M Connect software tool.

Typical applications.
Speed control for conveyors, fans, positive displacement pumps and mixers - applications where functions are controlled remotely via fieldbus or Ethernet communications.

Emerson drive Unidrive M200 series - motor control performance and energy saving.

Performance motor control.
Unidrive M200 combines the latest microprocessor technology with unique motor control algorithms to give maximum stability of induction motors at all powers. Current loop update rates of up 125 μs and complementary intelligent control features ensure that machine throughput and energy efficiency is maximized in all industrial applications.
Motor control modes include:

Easy motor pairing.
Several intuitive tools are available to guarantee fast and optimized pairing between M200 and AC induction motors. These include: 
- Easy-to-use keypad with parameter reference guide on front panel 
- Multilingual LCD remote keypad with clear parameter and diagnostic descriptions (remote real time clock keypad also available) 
- Two autotune procedures (stationary and rotating) to automatically optimize motor and drive configuration 
- Unidrive M Connect software tool providing a comprehensive motor database and set-up wizard.

Energy saving.
With energy costs a key factor in many industries, Unidrive M is packed with features to enhance energy efficiency: 
- Low power standby mode for applications where drives can sit idle for significant periods
- Automatic 3-speed cooling fan keeps energy usage and acoustic noise to a minimum by intelligently responding to load and environmental conditions 
- Square law V/F mode is optimized for quadratic loads like pumps and fans to keep motor losses to a minimum 
- Dynamic V to F mode keeps energy usage and motor losses to a minimum in low load conditions 
- Unidrive M200 is highly efficient (above 98 %)

Fast and easy set-up, monitoring and diagnostics with Emerson vfd Unidrive M200 series.

Unidrive M keypads, memory devices and software tools make it easy to access Unidrive M200’s full feature set, allowing users to optimize drive tuning, back up parameters and troubleshoot more quickly.

User interface options.
Unidrive M benefits from a number of optional keypad choices to meet your application needs.
