With safe motion, safety functions are easily applied in the servo amplifier via the safety card PMCprotego S, thereby providing a drive-integrated solution for motion monitoring. The STO "safe torque off" function is included even in the basic version of the servo amplifier PMCprotego D. This provides a flexible, scalable safety solution. You decide individually how many safety functions your application needs.
Unlike external solutions, in addition to the available rotary encoder signals, PMCprotego DS can use internal system variables such as terminal voltage, EMF (electromotive force) or motor currents for safe motion detection. As well as the fact that less wiring is involved, an integrated solution also has the benefit of a shorter reaction time to errors.
The SLS ("safely limited speed") function, for example, is available for setting up the machine. The converter monitors the speed internally and, in the event of a fault, responds much more dynamically than would be possible when using an external monitoring circuit that switches off the drive.
