12 SINAMICS “Standard Drive Control” and “Dynamic Drive Con-
trol” application classes to simplify commissioning and increase
the degree of ruggedness of the closed-loop motor control.
The SINAMICS application classes are available with the fol-
lowing inverters:
• SINAMICS G120C
• SINAMICS G120 with PM240, PM240-2 and PM330 Power
