A-B 8520-4APA1 digital processor drive

A-B 8520-4APA1 is a digital processor drive in the Allen-Bradley 9/440 4-axis CNC system. The 8520-4APA1 system module and the axis module make up the Allen-Bradley 9/440 system. The 8520-4APA1 requires a precise AC input voltage with pre-defined phase/frequency/amplitude, and it is the primary function of the axis module to provide this controlled AC voltage by converting the DC voltage provided by the 8520-4APA1 system module. 

The 8520-4APA1 requires a precise AC input voltage with pre-defined phase/frequency/amplitude

The axis module provides a controlled AC voltage to the 8520-4APA1 by converting the DC voltage provided by the 8520-4APA1 system module .

▪ Active unit does not automatically switch to primary on resynchronization 

▪ Critical control data plus all redundant outputs must be included in the output data transfer 

▪ Bumpless switchover from active unit to backup unit
