The automatic control ranges from basic to fully automated. The basic functionality includes all necessary safety features required by the standards and/or the grid operator. PLC controls provide all the possibilities offered by these industrial controls (digital, analog, RS485, etc.)

The basic functionality consists of: protection against overcurrent, overload, overvoltage, undervoltage, overfrequency and underfrequency. Power factor improvement is also applied to induction generators.

When controlling with a PLC, both physical control with switches and software control with a web server are realized. This allows the mill to be controlled in all cases. PLCs are supplied with an IXON router so that the control of the mill is available via a VPN on a smartphone, tablet, PC or MAC.
