NOTE
Planning
You will find help with the selection of the optimal operation mode (with Power
Supply Unit or with AC-AC Servo Drive) in
.
NOTE
Pay attention to Operation Manual for AC-AC Servo Drive!
On setting up a multi-axis system with AC-AC Servo Drives as the supply, it is
imperative the "MSD Servo Drive AC-AC Operation Manual"
(ID no. CA65642-001) is followed.
8.1 Arrangement of the devices and
components
The positioning of the components in the switch cabinet has a significant e fect on the
trouble-free system and machine function using the multi-axis system. It is therefore
imperative you pay attention to the points in chapter 3 on mounting and in chapter 4.2
on the installation of a multi-axis system.
8.1.1
Device protection
During the installation of a multi-axis system with AC-AC Servo Drive as the supply, pay
attention to the following information on device protection:
Mains fuses
•
G392-004 (Size 1) to G392-072/G395-084 (Size 5)
In all circumstances the mains fuses are to be installed in addition to the motor
protection switch and will prevent irreparable damage to the device (e.g. if
there is a component fault or overload). Use mains fuses (utilisation class gG)
to isolate all poles of the DC-AC Servo Drive from the mains. You will find mo e
detailed information in the Operation Manual MSD Servo Drive AC-AC
(ID no. CA65642-001) in the chapter "
Electrical installation".
•
G392-090/G395-110 (Size 6) to G395-450 (Size 7)
Instead of mains fuses of utilisation class gG, semiconductor fuses of utilisation
class gRL (gS) ar
e to be used. As this type of fuse is a full-range fuse it offers
protection for the devices and the cabling. As a result the motor protection
switch is not required.
