Basic inverters, MOVIFIT® basic

MOVIFIT® basic, the decentralised basic inverter for efficient materials handling technology. Less is more: Sew Eurodrive has reduced the MOVIFIT® basic to include only the functions and features necessary, and its design means that it is the ideal inverter for the lower function range. The frequency inverter is available in power ranges of 0.75 kW and 1.5 kW.
Even before installing it, this basic inverter will convince you with straightforward and fast order processing. All you need to do is select the required power rating and control, AS-Interface or binary, and one of eight available unit variants. No additional consulting or project planning effort required.
The energy for AC 3 x 400 V is distributed via the FieldPower® terminal from Weidmüller, which is integrated in the unit. Two sensors can be connected to the unit in addition to the drive function when using AS-Interface. These are signaled to the system controller via AS-Interface master without additional costs and the signals can then be processed in the system controller.


  • Integrated FieldPower® contact block for energy distribution with modern and reliable connector technology
  • Simple connection and wiring technology
  • Consistent integration of power distribution components in the housing of the drive unit
  • Consistent use of standard plug connectors for control and motor connection
  • Extremely short assembly and installation times
  • When using AS-Interface, two sensors can, in addition to the drive function, be connected to the unit for direct communication with the system controller (everything included)
