Powerdrive variable speed drives are modular with air or liquid cooling and offers open or closed-loop vector or simple V/F control.
When designing the new Powerdrive variable speed drives, the engineers at Leroy Somer wanted keep components and wiring to a minimum, make them easy to install and commission, be reliable and offer simple maintenance.
Covering the range from 45 to 675kW, Powerdrive is modular with air or liquid cooling and offers 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.
Auto tuning is offered at the first start up and all the parameters can be saved to the Xpresskey with one click of a button.
Multilingual, PC-based commissioning software provides a motor database, user help and a setup 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.
The drives are also much less susceptible to power disturbances thanks to new technology developed in collaboration with EDF.
Powerdrive's enclosures available in 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.
