NOTICE
Damaged main insulation
In systems where direct drives are used on 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 rating of the infeed/regenerative feedback module
• The type of infeed/regenerative feedback module (particularly when an HFD commutating
• The number of axes
• 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 the use of the associated Active Interface
Note
Use an Active Interface Module or the matching HFD line reactor
Please note the following when connecting the motor to a SINAMICS S120 drive system:
The corresponding Active Interface Module or the appropriate HFD line reactor must be used to
operate the Active Line Module controlled infeed unit.
Note
Voltage Protection Module VPM
Above a speed defined for a particular motor type, each motor requires a Voltage Protection
Module VPM; also see Configuration Manual "SIMOTICS T-1FW6 Built-in Torque Motors".
