Working Principle of SIMODRIVE 611 Infeed Regenerative Feedback Module

The primary function of an infeed module is to convert incoming three-phase AC power into controlled DC power for the drive system DC link. The DC link then supplies energy to connected servo amplifiers and motor modules.

During normal acceleration and machining operations, the module transfers electrical energy from the mains supply into the drive system.

When servo motors decelerate, they generate electrical energy due to regenerative braking. Instead of converting this energy into heat through braking resistors, the regenerative feedback function allows energy to flow back into the electrical supply system.

The SIEMENS 6SN1145-1BA01-0BA1 manages this bidirectional energy conversion process while maintaining stable DC link voltage.

This operating principle improves system efficiency, especially in CNC machines with frequent acceleration and deceleration cycles.
