Standard Firmware for scalable control and functionality
Basic firmware
DCS550 firmware includes the basic functions of speed
control, armature current, field current and motor voltage. The
design of the drive logic enables a drive reaction defined by
Profibus standard, but can also configured to adapt classic
command structures.
Macros
The DCS550 is equipped with seven different macros to cover
the most frequent parameter settings.
Macros are pre-programmed parameter sub-sets. During
start-up, the drive can be configured easily without chang-
ing individual parameters. The functions of all inputs and
several outputs and of allocations in the control structure are
influenced by the selection of a macro. The means whether
the drive is speed-controlled or torque-controlled, whether
supplementary references are processed, which actual values
are available at the analog outputs, which reference value
sources are used etc. is already defined in the macro.
