When System Control Solutions was
tasked with designing the control
system for a complex pump test rig
suitable for use with pumps driving
motors ranging from just a few
kilowatts, up to more than 300, as
well as being capable of testing all
sizes over a wide range of operating
speeds, the company used a Vacon
NXP variable speed drive to address
the challenge.

For this application a Vacon NXP
series drive rated at 315kW was
selected. After installation of the Multi
Motor software, this was programmed
with eight different parameter sets,
enabling this one drive to
‘impersonate’ drives rated at 10, 50,
100kW and any one of another five
ratings to the maximum of 315kW.
