General Information
The function block is used to control the BM51xx active front end unit. (AFE)
With executing the function block, the DC link starts to charge. Also discharging is possible.
Furthermore error message can be read out, and errors possible to acknowledge.
To have these possibilties some defined connection to the AFE is necesserey:
1.) external wiring of digital in and outputs to the PulseEnabling Input and the Mains-switch
2.) PDO Mapping with ProMaster
The AFE dosn't included as Motion Control unit.
