D.2 Function
The mains rectifier BM5030 with safety function converts the AC voltage of the power
supply (U
AC
) to the DC link voltage for the decentralized drive solutions BM2500 (U
DC
/
U
DC link
). The STO function is integrated in this device, disconnecting the DC link voltage
(U
DC
) of the mains rectifier to the axes units (U
DC link
). This is a two channel disconnec-
tion, i. e. a switch disconnects DC link + and another DC link - (see figure below).
The STO function is available via connector X2.
