5.1.11 Selecting the drive system components for the power connection
The drive system components for the power connection are selected on the basis of the
peak and continuous currents that occur in the duty cycle. If more than one motor is
operated in parallel on a single power unit, the total values of the peak and continuous
currents must be taken into account.
NOTICE
Damage to the main insulation
In systems where direct drives are connected to controlled infeeds, electrical
oscillations can occur with respect to ground potential. These oscillations are, among
other things, influenced by
• The lengths of the cables
• The size of the Active Line Module infeed unit
• The size of the motor
• The winding design of the motor
• The type of line supply
• The place of installation
The oscillations lead to increased voltage loads and may damage the main insulation!
• To dampen the oscillations we recommend using the associated Active Interface
Module. For specific details, refer to the documentation for the drive system being
used or contact your local Siemens office.
Note
The corresponding Active Interface Module must be used when operated with an Active
Line Module controlled infeed unit.
