Power and signal connection
Only ring cable lugs are suitable for the power and signal connection at the motor end. Only
plug connectors with a full thread are suitable for the onward adapter cable. This is the
reason that cable extensions, for example, to the converter or to the SME12x, must also
have a full thread connectors. SPEED-CONNECT connections are not compatible.
Requirements
● The choice of Motor Module depends on the rated current or the maximum current of the
motor.
● The encoder system depends on the application
Note
Read the corresponding documentation about open-loop and closed-loop control systems.
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
• 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
The corresponding Active Interface Module or the appropriate HFD line reactor must be used
to operate the Active Line Module controlled infeed unit.
