Operating Principle
When the emergency stop pushbutton is actuated, the mains contactor in the
supply unit opens. The emergency stop relay or an auxiliary contact of the
mains contactor switches off the drive enable signals. The drives are shut
down according to the error reaction set in the drive controller.
The mains contactor is switched off and the DC bus short circuit (ZKS) takes
effect, when
●
the supply unit (Bb1 contact) outputs a drive error message
●
the control unit (CNC contact) outputs an error message
●
the limit switch (S2) is passed
