Emergency Stop strategies
The Emergency Stop function is defined in EN 60204 (VDE 0113), Para. 9.2.5.4.
Implementation of the Emergency Stop function :
Wiring recommendation can be found in the Application Note "Stop and Emergency Stop
Functions".
Category 0:
Category 1:
26
The controller enable is switched to "disable", the electrical supply is disconnected.
The drive must be held by an electromechanical holding device (brake).
In multi-axis systems with a coupled DC bus link, the motor cable must also be
disconnected by a changeover switch (a contactor, such as the Siemens
3RT1516-1BB40) and short-circuited by resistors connected in a star configuration.
If hazardous conditions can result from an Emergency Stop switch-off with an
uncontrolled run-down, the drive can be switched off after a controlled shutdown.
Stop Category 1 permits electromotoric (i.e. regenerative) braking with a switch-off
when zero speed has been reached. Safe shutdown can be achieved if the loss of
the electrical supply is not evaluated as a fault and the control system takes over
the disabling of the servo amplifier.
In normal circumstances, only the supply power is switched off in a safe manner.
The 24V auxiliary supply remains switched on.
