The PMIcontrol Basic-M frequency inverters are specially developed frequency inverters for mounting on internal rotor motors. The AMblue drive system is created by combination with IEC standard motors (asynchronous motors). The PMblue drive system is created in combination with PM motors (permanent magnet excited synchronous motors).

In the "Basic" version the frequency inverters are speed controllers and can be controlled, for example, by 0-10 V. The products can be extended functionally by pluggable add-on modules if necessary. Add-on modules enable integration into different bus networks. Functional expansion as a control unit is also possible via additional modules.

For fast start-up, the frequency inverter is equipped with a slot for the ZAstick parameter memory. Necessary operating and motor data for optimum energetic and acoustic operation of the appropriate motor or fan are saved on the pluggable ZAstick parameter memory for the frequency inverter. This parametrisation also sets the frequency inverter to the respective motor technology (IEC standard motor or PM motor). As soon as voltage is applied to the frequency inverter, the data are loaded and saved as a default setting.
