If the system includes several CCs 61xx that are connected to the same supply bus (X69) via a
UV supply module, only the last CC 61xx (usually the rightmost unit) must be connected
to the UV via X74. The other CC 61xx units are then supplied via supply bus X69.
If several CC 61xx units are supplied by more than one UV supply module, which means that they are
connected to different supply bus systems (X69), then the last CC 61xx (usually the unit at the extreme
right) of the respective supply bus must also be supplied with the additional +5 V of the UV via X74.
Check whether the +5 V supply of all drive-control motherboards is present. The voltage is displayed
in the DriveDiag diagnosis tool. On the "Voltages and currents" tab for the drive control boards, you will
find the +5 V supply voltage. The value of this voltage should not be below +4.90 V.
