Electrical connection
8.3 System integration
Signal connection for stator segments higher than 66 A
Only fully-threaded plug connectors can be used to connect signals. SPEED CONNECT
connections are not compatible.
Power and signal connection for stator segments up to 66 A
For the power and signal connection of stator segments with a current demand up to 66 A,
prefabricated cables with fully-threaded plug connectors or SPEED CONNECT plug
connectors can be used.
Suitable cables are listed in the catalog.
Note
O-ring
Remove the O-ring from the SPEED CONNECT plug connector before connecting it to a
SPEED CONNECT mating plug connector.
For plug connections comprising SPEED CONNECT and fully-threaded plug connectors, the
O-ring is required to ensure that the connection is tight and resistant to vibration. Do not
remove the O-ring if this combination is used.
Even if a SPEED CONNECT plug connector has been correctly connected to a fully-
threaded plug connector, a gap will remain between the connector and mating connector. Do
not try to eliminate this gap by tightening the connectors further. This could damage the plug
connector.
Requirements
● The following components are selected depending on the current and/or power demand
of the segment motor:
– Motor Module
– Active Line Module ALM with associated Active Interface Module AIM, including line
Other important related factors are the line voltage, regenerative feedback, and the DC
link voltage.
● The encoder system used must be harmonized with the particular application.
● Read the corresponding documentation about open-loop and closed-loop control
systems.
