The implementation of the basic drive functions into the firmware offers many advantages for the
user:
• The basic functions are always directly available.
• The interfaces to the basic functions are standardised and thus identical for all technology func-
tions.
• Uniform dialogs provide a uniform "look & feel".
• The internal function state control guarantees that
• only one basic function at a time controls the drive.
• only one basic function with the highest priority is executed if several basic functions are ac-
tivated at the same time.
• the drive is always in a defined state, both in case of an error and in standard operation.
• All basic functions are synchronised to each other. You can change between the basic functions
online while the drive is rotating.
• The processing speed is optimal.
