A Project planning
A.1 Overview and comparision of
multi-axis systems
This overview presents the two possible system variants for Moog multi-axis systems:
"Operation with power supply unit" and "Operation with AC-AC servo drive as sup-
ply". It will help you to judge the optimum variant for your application. Aspects such as
available installation space, complexity of installation, acquisition and operating cost are
considered.
!
ATTENTION!
• The variants set out in this section relate solely to devices and components
of the MSD Servo Drive product family (excluding MSD Servo Drive Com-
pact). Operation with devices or components from other manufacturers or
product families is not permitted!
• For each application, a number of specific factors, such as total power
output and simultaneity, must be individually considered in order to ensure
safe system operation.
• You should always consult Moog's Project Support advisors when planning
your application. They will be able to balance all the parameters using a
powerful project planning software program.
• Commissioning of a MSD Servo Drive multi-axis system should only be un-
dertaken following dimensioning by Moog's Project Support department!
A.2 Application examples
The MSD Servo Drive multi-axis systems are able to demonstrate their advantages over a
conventional system comprising multiple AC-AC servo drives particularly in applications
which often feature regenerative operation. Depending on the length of the regenera-
tive phases, and whether other system axes are in motorized mode during those phases,
operation either with a power supply unit or a AC-AC servo drive as the supply source
may be preferable.
