In addition to the total power tap, the total DC link capacitance of the axis network also
needs to be considered. The maximum total DC link capacitance of the AC-AC servo
drive must not be exceeded. In this regard refer to tableA.6 and to tableA.5 on page

Table A.6 DC link capacitance and Maximum total DC link capacitance of the AC-AC servo drives
!
ATTENTION!
• Observe switching on sequence
The mains voltage is only allowed to be switched on after switching on the
24 V DC supply voltage for the control electronics and conclusion of the
initialisation phase.
• Observe power classes
It is only allowed to connect DC-AC servo drives of lower or the same
power class to an AC-AC servo drive.
• Observe maximum number of axes
It is allowed to operate a maximum of six DC-AC servo drives on one sup-
plying AC-AC servo drive.
Calculation example: Feed from a AC-AC servo drive
Two DC-AC servo drives G393-024, two DC-AC servo drives G393-060 and one
DC-AC servo drive G393-090 (air-cooled) are to be connected to an AC-AC servo drive
G392-170.
Calculation: 1 x 4240µF + 2 x 504µF + 2 x 900µF + 1 x 1060µF = 8108µF
Result: The AC-AC servo drive is adequately dimensioned with a maximum
total DC link capacitance of 9200µF.
NOTE: Note that not only the DC link capacitances of the DC-AC servo drives,
but also of the supplying AC-AC servo drive, need to be considered.
A.7.7 External components
When using a AC-AC servo drive as the supply source you will need additional compo-
nents:
• Mains filter
• Mains choke
• Braking resistor
• EMC fixings
