As all the work is done inside the drive, no additional parts are necessary.
Additional RFC-A mode means you’ll benefit from consistent running speeds, at current loop rates as low as 125μs. Plus flexible system integration makes it possible to connect the drive to almost all communication protocols. The inclusion of an onboard PLC gives more control, at no extra cost.
As with all Unidrive M General Purpose drives, fit for purpose is our key priority. That means they are easy to install and built to last.
Conform to safety standards, maximize uptime and reduce costs by integrating directly with safety systems
Unidrive M300 has integrated dual STO inputs for SIL3, PLe conformity, eliminating the need for external safety components.
Flexible system integration with SI communications options
SI interface enables integration with a wide range of available industry standard fieldbuses and I/O.
AI-485 Adaptor option permits connection to RS485 networks using Modbus RTU.
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.
Removes the need for additional PLC and caballing.
Easy to set-up
Designed to make set-up as simple as possible.
Many applications require changing just a few settings.
Adjustments are easy with the keypad and clear step-by-step guide.
Useful parameter guide located on the front of the drive.
Concise parameter set for ease of use.
For fast, batch production, parameters can be transferred to new drives using standard SD card with AI-Backup module or AI-Smart adaptor.
Reduced application size and cost
Unidrive M drives are amongst the smallest in their class.
Drives can be fitted side-by-side to save even more space.
Designed for easy assembly in or out of a cabinet.
DIN rail mounting supported below 1.5kW.
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.
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.
