Ready-to-use variable speed drive Solutions for High Power Process Applications
Open the catalog to page 1Innovative variable speed packages to reduce energy bills Reduction of energy costs: a challenge for the industry The need for energy has kept increasing and has now become a worldwide concern. Within industry it now represents more or less 30 % of the world wide energy used, mainly driven by applications linked to process typically including pumps, fans, compressors and crushers. Currently these applications are mainly operated at fixed speed. Conversion to variable speed is a proven solution cutting energy costs by as much as 50%. The savings generated, combined with the reduction of...
Open the catalog to page 2Nidec: fully committed to high energy efficient solutions In full awareness of the challenge, Nidec has built a complete offer of motors, drives and services, fully focused on energy savings: • IMfinity®: a range of induction motors available in IE2 or IE3 efficiency levels. • Dyneo®: Permanent Magnet motors and drives packages with efficiency exceeding IE4 level over a wide speed range • Powerdrive: range of variable speed drives designed for process applications Powerdrive F300: IP20 drives ideal for integration into cubicles Powerdrive MD2: complete IP21 or IP54 “Ready-to-use”...
Open the catalog to page 3Much more than energy savings using variable speed in process applications Pumping (distribution, irrigation, desalinization, treatment) • Savings on maintenance costs when removing the flow regulation valves • Full control of acceleration and deceleration preventing water hammers • Leakage, pipe break or loss of prime detection • Automatic cleaning cycle on pump clogging Waste Water Treatment (agitation, bubbling, centrifugation) • Better oxygenation in aeration basins • Adaptation of installation to the variable load • Limitation of wear mainly on mechanical aerators • Better control of...
Open the catalog to page 4The retrofit of an installation or the conversion from fixed speed to variable speed of a system requires various arrangements like fitting the drive in an existing environment, handling the power wiring or interfacing the controls with other equipment. The difficulty of addressing all of this is more important as the power is high, where the solution needs to be flexible enough so it contributes to keeping the investment costs down. Powerdrive MD2: THE all inclusive ready-to-use solution ! Thanks to our strong experience resulting from close partnerships with end users and OEMs, Nidec is...
Open the catalog to page 5A complete system engineered, wired and tested Powerdrive MD2 is ready-to-use ! Three phase power supply The integration of a variable speed drive in a system requires engineering, component sourcing, fitting and wiring, as well as testing. The Powerdrive MD2 has been set-up so it provides a complete system including all equipment needed for protecting, controlling, interfacing and running the application with full safety. Emmergency stop Line disconnect Line interrupter with lockable front handle -S 1 Option fitted and wired, allowing motor isolation from the power supply for safe...

Open the catalog to page 7Compact and robust Powerdrive MD2 can be fitted anywhere Finding a suitable space to add the drive to an installation, especially when it is a high power, may not be so easy. The resistance to the environment, protection of personel, mounting flexibility, EMC management, mechanical robustness are major considerations which have been taken into account while designing the Powerdrive MD2. Powerdrive MD2: A complete solution in a compact size Up to 250 kW, Powerdrive MD2M, all inclusive, is available in a wall mount version. In addition to its compactness, it provides great flexibility in...
Open the catalog to page 8Outstanding thermal behavior The robust design of Powerdrive MD2 allows for operation in a range ambient conditions and unusual temperatures: • Operation at 50°C ambient permanently with adapted sizing • Operation at 70°C for 1 hour in exceptional circumstances like smoke extraction in public buildings Fire Mode When operating conditions limits are exceeded, the drive trips to protect itself. However, there are certain emergency situations where the drive must run whatever the conditions are (smoke extraction fans in tunnels, car parks and fire pumps). Powerdrive MD2 allows for the...
Open the catalog to page 9Simple and user friendly To facilitate commissioning and operation Operating a drive during its life time requires different levels of access. Each of them with specific needs: • Simple and quick set-up during drive commissioning • Saving the settings in order to easily and quickly duplicate while guarantying repeatability • Displaying the operating data for running the application efficiently • Generating clear alarms prior to tripping or on programmable conditions • Providing diagnostic tools after a trip will allow quick and safe restarting User friendly interface The 4.3 " color screen...
Open the catalog to page 10Easy and direct access to drive data As the skills of people authorized to set-up a drive may be different to those authorized to enter into electrical equipment, Powerdrive MD2 provides full access to the controls through a USB port located on the front panel. This USB port allows a laptop to communicate with the drive without powering-up the drive. The Nidec MDX-SOFT commissioning software, which can be downloaded from the web for free, provides a number of features like: • Drive setting by downloading an existing parameter file or by using simplified interactive macros or advanced...
