FREQUENCY INVERTERS

"What must a motor control be capable of?"

This is the constant question for system engineers. The answer determines the required performance.

"All in one" is at first glance a good advertising slogan, but for the customer it can be an expensive and unnecessary solution. Achieving maximum performance from minimal investment is the basic goal of the F4 and S4 inverter series. The performance levels make it possible to create the optimum solution:

• basic variable speed – F4-s;
• application specific programming – F4-c;
• optimum control of induction motors with regulated field oriented control – F4-f;
• maximum dynamic performance with the AC servo series – S4.

You can be assured of easy startup with limited personnel training due to simple parameter structure, uniform connection, low profile mounting technique.

The following communication protocols are supported: INTERBUS and InterBus Loop, Profibus DP/FMS, CAN, LON, DIN66019.
