The 6SE7021-8TP50 model from Siemens serves as an effective motion control drive inverter unit. This unit accepts input voltage levels spanning from 510 to 650 volts DC, while delivering a nominal power output of 7.5 kW. It can also achieve a horse power capacity of 10.1.

With regard to operational specifications, the rated output current reaches 17.5 amperes, while it can manage short-time current loads of 52.5 amperes. This inverter requires a power supply of 380 to 480 volts AC and operates efficiently across an input frequency range of 50 to 60 Hz. The rated phase configuration for this device is 3-phase, and it can produce an output frequency between 0 and 400 Hz, allowing for flexible control of motors.

In terms of physical dimensions, the inverter measures 14.2 inches (360 mm) in height, 15.3 inches (135 mm) in width, and 10.2 inches (260 mm) in depth. The unit has a weight of 19.62 pounds (8.9 kilograms), making it manageable for installation. During operation, the total power loss is rated at 0.3 kW when functioning at 5 kHz.

For installation needs, the maximum cable length supported ranges between 50 to 140 meters for shielded cables, and 70 to 100 meters for unshielded cables, especially in the frequency range of 5 to 10 kHz. Additionally, the inverter conforms to a protection rating of IP20, providing adequate safety against access to hazardous parts.
