Drives Based Safety Integrated With SINAMICS Drives
The SINAMICS drive family Complete regarding power ratings and functionality Wide range of power ratings from 0.12 kw to 85 MW Available in low voltage, medium voltage as well as DC voltage versions
Drive Based Safety Integrated Functions An enabler for new machine concepts Demands of the new machine landscape Higher production throughput High efficiency / less waste Cost pressure Modular yet more integrated design Increasingly automated (i.e. Robots)
Why Safety Integrated Technology in Drives? Man Machine Process Drives are frequently used to control the direction of movement and speed of equipment and machines generally, these drives are associated with potentially hazardous motion that must be safely shutdown using suitable protective equipment and devices Using the safety functions integrated in SINAMICS drives, innovations in safety, productivity, and efficiency can be realized
STO (Safe Torque Off) The most basic safety function After STO is activated, the energy supply to the motor is interrupted in a safety-relevant fashion and as a consequence the motor coasts down un-braked After STO has been activated it is not permissible that the drive generates torque resulting in hazardous motion Frequency Actual Frequency Setpoint Frequency Time
Safety control system Key functions Analyze Evaluate React All from a single source Integrated safety solutions for recording, evaluating, all the way to responding.
