Motor Modules:
● No more than 6 Motor Modules should be connected to a DRIVE-CLiQ line on the Control
● Motor Modules should be connected directly to the Control Unit in vector control.
● In servo control Motor Modules should be connected to a DRIVE-CLiQ line together with
● If the Motor Modules need to be distributed to two DRIVE-CLiQ lines (e.g. on account of
● Only one end node should be connected to free DRIVE-CLiQ sockets within a DRIVE-

Unit (including with vector, V/f control).
– If the DRIVE-CLiQ socket X100 is already assigned to a Line Module, the DRIVE-
CLiQ socket X101 should be used.
– Several Motor Modules should be connected in a line.
– If there is already a Line Module present at X100, the Motor Module should be
connected in line to socket X201 of the Line Module.
– Several Motor Modules should be connected in a line.
the Line Module.
– Several Motor Modules should be connected in a line.
– If there is already a Line Module present, the first Motor Module should be connected
in line to socket X201 of the Line Module.
– If there is no Line Module present, the first Motor Module should be connected directly
to the Control Unit (recommended DRIVE-CLiQ socket: X100).

on the Control Unit should be used.
Example, vector control in chassis format:

– Motor Module current controller cycle 250 µs: X101
– Motor Module current controller cycle 400 µs: X102
