Energy efficiency

SINAMICS G120P increases the efficiency and minimizes energy consumption in the complete process chain. The inverter has integrated hardware as well as software functions as standard. The main features are:

• PM230 Power Modules up to 90 kW: Extremely high active power component of apparent power thanks to efficient inverter topology. For the same drive power, the inverter requires a lower line current than comparable inverters
• Flux reduction through automatic adaptation of the motor current to the prevailing load conditions with closed-loop control modes U/f (ECO) and vector without sensor (SLVC) and savings of up to 5 % under partial load conditions
• Sleep mode dependent on setpoints in the process
• Automatic switchover to line operation is possible at rated speed (bypass mode)

Optimum energy management through innovative technology

Optimized inverter topology for PM230 Power Modules

• Compliance with limits for line harmonic distortion in accordance with EN 61000?3?2, EN 61000?3?12 or EN 61000?3?4 (R_SCE > 250) without a line reactor
• Reduced apparent power as a result of high power factor ? = 0.9
• Smaller cable cross-sections can be used because mains power consumption is reduced

Flux reduction

• Energy-saving capability through automatic adaptation of the magnetic flux in the motor to prevailing load conditions (lower motor losses under partial load conditions)

Sleep mode

• Energy-saving capability: The drive is started/stopped in line with the currently applicable setpoints, thereby avoiding excessive mechanical loads

High efficiency

• ? ? 98 % with PM330 Power Module
