Short description
Frequency inverters for motor and wall mounting, V/f
control without encoder, vector control without speed
feedback, optionally with integrated safety functions,
fieldbus communication, pluggable memory chip for
the parameter set, high operational reliability thanks to
a thermally independent system
Frequency inverter for wall mounting, vector control
with and without speed feedback, overload capacity up
to 180 %, optionally with integrated safety functions,
fieldbus communication, pluggable memory chip for
the parameter set, high operational reliability thanks to
a thermally independent system
