With safe motion, safety functions are easily inserted into the servo amplifier by using the safety card PMCprotego S, thus providing a drive-integrated solution for the monitoring of movements. The STO ("Safe Torque Off") function is already included in the basic version of the servo amplifier PMCprotego D. This provides a flexible, scalable safety solution. You decide individually how much safety your application needs.
Unlike external solutions, PMCprotego DS can - in addition to the available rotary encoder signals - make use of 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 internally monitors the speed 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.
