5. Safety Concept 2 Safety Concept In case of danger any potential risk to a machine must be eliminated as quickly as possible Dangerous movements can generally be bringing the unit to standstill and applying restart prevention MOVITRAC B is characterized by the optional connection of X17 to an external fail safe prototype tested emergency stop relay The emergency stop relay disconnects all active elements disconnection of the safety oriented 24 V power supply of the output stage control that generate the pulse trains to the power output stage IGBT when a connected control device E STOP button with latching function is activated Disconnecting the 24 V voltage supply at connector X17 ensures that the supply volt ages required for operating the frequency inverter and consequently for generating a rotating field of pulse patterns which allow the generation of a rotating field are safely interrupted preventing automatic restart Instead of separating the drive galvanically from the power supply using contactors or switches the disconnection procedure described here prevents the power semi conductors in the frequency inverter from being activated thus ensuring safe discon nection This process disconnects the rotating field generation for the respective motor The individual motor cannot develop any torque in this state even though the mains voltage is still present The requirements for the safety control are clearly def
