Overview
Easy and clearly arranged parameter setting of the 3RW44 soft starter
with Soft Starter ES 2007
The Soft Starter ES software permits the quick and easy
parameterization, monitoring and diagnostics of
SIRIUS 3RW44 High-Feature soft starters for service purposes.
The device parameters can be configured directly on the PC
and transferred to the soft starter through a serial cable or an
optional PROFIBUS/PROFINET interface.
