Abstract: The role of the SINAMICS G120 series variable frequency drive (VFD) has been instrumental in the field of industrial control systems and the control of AC induction motor drives that contribute to optimized energy efficiency. Thus, the present paper aims to carry out an in-depth comparative study and analysis of the commissioning of the SINAMICS G120 AC drive system, comparing the manual mode of commissioning, which may be achieved through the use of operator panel devices such as BOP-2 or IOP, and software commissioning achieved through tools such as ‘Start Drive in TIA Portal.’ Moreover, through experimental models of the 1.5 kW rating AC induction motor, the performance evaluation of the result will be discussed in detail. Different case study scenarios have already proven that software commissioning offers reliable results, i.e., 32% less rise time for speed, 66% less error, and thus efficient startup, ensuring higher energy savings. Research gaps were identified in PLC-VFD control systems, which have been addressed in the current study for application within Industry 4.0 scenarios.
