Variable speed drives easy to install
A
Leroy Somer product story
Edited by the Manufacturingtalk editorial team
Mar 1, 2007
Leroy Somer has kept components and wiring to a minimum in its new Variable speed drives to make them easy to install and commission, to be reliable and offer simple maintenance.
When designing the Powerdrive variable speed drives, engineers at Leroy Somer wanted to 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 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 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, for example.
The drives are also much less susceptible to power disturbances thanks to technology developed in collaboration with EDF.
Powerdrive's 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.
