Emerson VFD Drives Unidrive M300 industrial series

Emerson frequency inverter Unidrive M300 series - Optimized throughput, open automation systems, maximum ease of use.

Led by the results of extensive customer-driven market research, we have tailored six Unidrive M feature-sets to specific application needs identified within industrial applications.The Unidrive M300 adds integrated machine safety for open loop applications to the family.

Emerson Unidrive M300 series integration through safety and flexible communications.

Unidrive M300 is ideal for applications that require cost effective integration into safety systems and advanced Rotor Flux Control (RFC-A) open-loop motor control. Unidrive M300 provides an upgrade path for Commander SK users who want a similar feature set with the addition of integrated dual Safe Torque Off (STO) inputs to provide SIL3/PLe conformity and enhanced RFC-A open loop motor control.

Integrate Unidrive M300 into any safety system.
With dual STO, M300 can easily become part of machine safety systems and conform to SIL3/PLe. The ‘SI’ Interface enables further 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.
M300’s advanced Rotor Flux Control (RFC-A) utilizes closedloop 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 M300 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 adaptor. An easy fit remote LCD keypad is available for IP66 (NEMA 4) 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 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 M300 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. M300 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 M300 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 M300’s compact drive dimensions are among the smallest in class at every power rating.

Upgrade Commander SK designs and installations with Safe Torque Off.
Unidrive M300 is designed for easy migration from Commander SK. Tools are available for fast and easy installation:
- Compatible dimensions, along with retrofit kits, mean that M300 can easily fit into Commander SK locations using existing fittings 
- Same power and control wiring philosophy 
- Parameter porting from Commander SK to Unidrive M300 is supported by the Unidrive M Connect software tool.

Typical applications.
Speed control for material transport and cutting, woodworking and machine tools where protection to people or assets is required to SIL3/PLe.

Fast and easy set-up, monitoring and diagnostics with Emerson vfd Unidrive M300 series.

Unidrive M keypads, memory devices and software tools make it easy to access Unidrive M300’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.

Unidrive M Connect commissioning tool.
Unidrive M Connect is our latest drive configuration tool for commissioning, optimizing and monitoring drive/system performance. Its development draws from extensive user research, using human centered design principles to give the ultimate user experience: 
- Task based commissioning is simplified via familiar Windows interface 
- Intuitive graphical tools enhance and simplify user experience 
- Dynamic drive logic diagrams and searchable listings 
- Drive and motor performance can be optimized with minimal specialized drive knowledge 
- Supports the import of Commander SK parameter files and allows full drive cloning 
- Multiple simultaneous communications channels for a more complete overview of the system 
- Drive discovery gives the ability to find drives on a network automatically without the user having to specify their addresses 
- Automatic RTU baud rate scanning on the Unidrive M300 RS485 connection.

Portable SD memory card.
Unidrive M300 uses popular SD cards for quick and easy parameter and program storage using the AI-Back-up Adaptor.
