A chemical industry inverter comprises a SINAMICS G120 inverter (Power Module and Control Unit) and the CM240NE chemical industry module.

The CU250S‑2 DP is a suitable Control Unit for this application. This is a Control Unit with integrated safety-related functions and PROFIBUS DP interface.

The following Power Module versions are used:

• PM240 Power Module with DC braking function and braking chopper, 400 V line supply voltage
• PM250 Power Module with energy recovery capability, 400 V line supply voltage

Depending on the power unit, additional components may be necessary to complete the system.
