freeMax
optimize & save energy
The main purpose of the Windows™ based freeMax program is optimizing motor characteristics of a STEPS8000 drive unit in a very individual way. Most freeMax fans use this tool to modify the Eco mode in a very economical way to save energy and so get more out of a battery charge.
The usage of freeMax is completely free of charge.
