CAUTION
!
Damage to your system/machine due to uncontrolled or
inappropriate commissioning.
The device may suffer irreparable damage.
• Pay attention to switch-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.
• Pay attention to 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.
• Pay attention to maximum number of axes
It is allowed to operate a maximum of six DC-AC Servo Drives on one supplying AC-AC Servo
Drive. If your requirements are higher, please consult your project engineer.
Example calculation: supply from an AC-AC Servo Drive
Two DC-AC Servo Drives G393-024/G397-026, two DC-AC Servo Drives G393-060/
G397-070 and one DC-AC Servo Drive G393-090 are to be connected to one AC-AC
Servo Drive G392-170/G395-210.
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 it is necessary to take into account not only the DC link capacitance
of the DC-AC Servo Drives, but also the capacitance of the supplying
AC-AC Servo Drive.

External components
On the usage of an AC-AC Servo Drive as the supply you need additional components:
•
•
•
•
•
Mains filte
r
Mains choke
Braking resistor
EMC fastening material
Possibly ferrite toroidal cores over the motor cable
