Figure 1: Block diagram “safe stop” as per EN 954-1 category 3
If the “safe stop” function is not needed, bridge pins 1 and 2 to [X3].
A “safe stop” as per EN 954-1 category 3 requires two channels, i.e. a restart must be safely
prevented two ways, completely independent of each other. These two ways of interruption, the power
supply to the drive and the safe pulse inhibitor, are called shut-down paths.
1. Shut-down path:
Output stage enabling via [X1] (inhibition of PWM signals; die IGBT drivers will no longer be
addressed with modulation patterns.)
2. Shut-down path:
Interruption of power supply to the six output stage IGTBs via [X3] by means of a relay (relays will cut
the power supply to the IGBT optocoupler drivers to prevent PWM signals from getting to the IGBTs.)
Between the triggering of the output stage supply relay and the monitoring of the driver supply a
plausibility test will be performed in the µP. This will detect errors in the pulse inhibitor and will also
suppress the error message E-05-2 ("Driver voltage fault") occurring during normal operation.
