Siemens Inverter Drive, 22 kW, 3 Phase, 380 → 480 V ac, 44 A, SINAMICS G120X Series

Power units with DC link reactor for extremely high active power component thanks to efficient converter topology - for the same drive power, the converter requires a lower line current than comparable converters Flux reduction through automatic adaptation of the motor current to the prevailing load conditions with closed-loop control modes V/f (ECO) and vector without sensor (SLVC) and savings of up to 5 % under partial load conditions Hibernation mode dependent on set points in the process High efficiency η ≥ 98 % Local commissioning without specialized knowledge of converters thanks to default settings and graphical user interface Unique: SINAMICS SD memory card for pre-parameterization and cloning of converter data sets Data backup for easy replacement Commissioning/diagnostics and controlling of converters Four integrated PID controllers Distributed closed-loop control for motor-independent process control without higher-level controller (PLC) Three freely programmable digital timer switches Control for freely selectable daily and weekly programs
