3.6 Technical data
3.6.1 Electrical data
The logical inputs and outputs of the inverter can be wired for the logic type 1 or logic type 2.
Logic type Active state
1 Output drawing current (source)
Current flows to the input
2 Output emits current from the input
Power source (sink)
Safety functions are only used in sink mode; source mode is not compatible with the safety functions.
The signal inputs are protected against polarity reversal, while the outputs are protected against short circuits. Both
the inputs and the outputs are electrically isolated.
3.6.2 Capacity of the safety functions
3.6.2.1 The safety functions of the safety-relevant power frequency inverter PDS(SR)
If, for the achievement of the qualitative and quantitative security objectives of the end application, certain adjust-
ments must be made to ensure that the security functions can be used in a safe manner, the BDM-integrator is
responsible for these additional developments (e.g. management of the mechanical motor brake).
In addition, the output data generated when using the safety functions (standard relay activation, controlling the
brake logic relay, error codes, information on the display, etc.) do not comprise safety-related features.

individual components of the safety function (according to SIL 2 CL for ACOPOSinverter P84) are differentiated between.
