Minimize downtime for critical operations
Unidrive M high power modules have exceptional build quality based on over 40 years' of drive knowledge, expertise and development
Emerson Automation Centers are situated in all global regions to provide local design consultation and rapid specialist technical support
Reliability assured
Every Unidrive M power module has been thoroughly tested in environmental chambers that cycle a wide range of load and thermal conditions
PCBs have conformal coating to further increase resilience to harsh environmental conditions
Trip avoidance features take intelligent action instead of interrupting critical processes
Protection alarms safeguard the wider system
Intelligent variable speed fans ensure operating temperature stays within limits
Wide supply voltage tolerance keeps drive operation smooth in areas where supplies are variable
Create flexible systems easily
The modular approach to building high power systems provides machine builders with flexibility while keeping complexity low
Modules with integrated rectifiers and/or line chokes can be easily paralleled
Separate inverter and rectifier modules (D, RECT..A and RECT..T) can be paralleled into common DC bus and regenerative configurations
Flexible and easy system design
Unidrive M high power modules are designed to fit in standard 600 mm deep x 400 mm wide (23.6 x 15.7 in) cubicles
6,12,18 and 24 pulse input and Active Front End configurations are easy to achieve
Integrated cooling fan power supply means no additional power supplies are required
Output current ratings have been increased to use fewer modules per system
A common control interface ensures a consistent programming method and feature set across the whole Unidrive M range
Make compact, easily maintainable systems
Overall system size and footprint is kept to a minimum
Manageable small and light modules are maintained and replaced rapidly and easily
Reduce spares inventory
Unidrive M’s modular approach gives customers the opportunity to standardize their solutions in order to keep spares holding to a minimum as different systems can be serviced using one common spare. Large volumes of standard product modules are stocked at local distribution hubs in convenient locations around the world meaning that rapid delivery is always available to all customers.
Upgrade Unidrive SP modular systems painlessly
Migration of Unidrive SP modular systems to Unidrive M is fast and easy:
Parameter porting tools such as Unidrive M Connect and Smartcard are available
SyptPro can recompile SM-Applications programs for SI-Applications, and can connect to existing CTNet networks
Identical width and depth dimensions, along with retrofit kits, mean that Unidrive M modules can easily fit into SP modular locations using existing fittings
Environmental safety and electrical conformance
UL listed
Electromagnetic immunity complies with EN 61800-3 and EN 61000-6-2
Electromagnetic emissions comply with EN 61800-3:
Onboard EMC filter, category C3
Optional external EMC filter, category C2 depending on power rating
Compliance with EN 61000-3-12 with external line reactor
Create high performance solutions
Switching frequencies of up to 16 kHz in systems up to 160 kW (250 hp) and 8 kHz in systems up to 250 kW (400 hp) allow Unidrive M to provide precision torque
Highly accurate thermal model ensures:
High overload capability – 150% Heavy Duty
Impressive low derating requirement in applications that demand high torque at low speeds. Power device temperature is intelligently managed meaning smaller lower priced systems can be specified and product life is extended
Dynamic Active Front End configurations provide:
Precision torque linearity across quadrants
Corrective power factor operation (lagging, unity or leading) for high quality power
Harmonic mitigation
