is a vector-controlled frequency inverter, perfectly equipped
for even challenging applications. Excellent drive behaviour,
even if not using speed feedback, and undreamed-of scope
for solving closed loop and feedback control tasks are just
Energy-saving
some of the features offered by these frequency inverters.
The power level is adapted such that the inverter is only driven
to suit the current demand for torque/power .
The 9300 vector is typically used in for example extruders,
winders, pumps, compressors, fans, blowers, sawing/cutting
drives, textile machines and conveyors.
Immediately ready for operation
The frequency inverters are preset for standard use. Amongst
other things, parameters are set for:

Predefined basic configurations are available for challenging
applications (e.g. dancer position control, torque control, tra-
versing control, digital frequency coupling).

standard applications can be undertaken using the 32 para-

however also be individually modified and set up with fre-
quently used parameters.
