They have succeeded beyond their greatest expectations.
Covering the range from 45 to 675KW, Powerdrive is modular with air or liquid cooling, and offer open or closed-loop vector or simple V/F control.
The individual inverter, rectifier, cooling and electronic modules make for easy accessibility and the front-panel-mounted HMI interface and optional remote keyboard make reading and writing the main parameters extremely simple.
Posted on the Enhanced Capital Allowance list, Powerdrive can be ordered already set-up for most major applications, allowing commissioning to be achieved with only eight parameters.
There is automatic auto tuning at the first start up and all the parameters can be saved to the patented Xpresskey with one click of a button.
Multilingual, PC-based commissioning software provides a motor database, user help and a set-up wizard.
The drive also tests itself at low voltage on initial switch on to avoid irreparable damage in the event of shorts or earths on motor phases, for example.
The drives are also much less susceptible to power disturbances thanks to new technology developed in collaboration with EDF.
The Powerdrive enclosures are to IP21 or IP54 and there are a host of options such as filters, encoders, units for most Fieldbus technologies, dynamic breaking and emergency-stop features.
Just at the time when you were beginning to think that all variable-speed drives were the same, Leroy Somer introduces the Powerdrive.
You owe it to yourself to check it out before you start your next motor drive project.
