smd – for simple applications
The frequency inverter has integrated motor overload protec-
tion. To achieve this a microprocessor calculates the motor

control cabinet tight and is your budget tight too? The smd
frequency inverter is a zero-compromise solution. The smd
covers a power range of 0.25 ... 22 kW and handles everything
The function and number of control terminals corresponds
to the usual Lenze standard:
you could possibly need of a universal use frequency inverter
today. A large range of applications can be easily solved using
clear functions.

ten as you want. Modified drive parameters are also handled
in a matter of seconds by simply replacing the EPM on the
front of the frequency inverter.
Programming is undertaken on the inverter itself or via a
battery-operated EPM (Electronic Programmable Module)
programming unit. Configurations can then be conveniently
produced or edited offline. The device saves up to 30 different
drive programs as a file. You can copy from EPM to EPM, file
to EPM or write the EPM back to a file in a couple of seconds
at the push of a button.
