12.10 Rules for wiring with DRIVE-CLiQ
● The motor encoder should be connected to the associated Motor Module:
Note
Automatically assigning an additional encoder
If an additional encoder is connected to a Motor Module, it is assigned to this drive as
encoder 2 in the automatic configuration.
● DRIVE-CLiQ sockets should, as far as possible, be symmetrically wired.
● The DRIVE-CLiQ cable from the Control Unit should be connected to DRIVE-CLiQ socket
● The DRIVE-CLiQ connections between the power units should each be connected from
● A Power Module with the CUA31 should be connected to the end of the DRIVE-CLiQ line.
● Only one final node should be connected to free DRIVE-CLiQ sockets of components
● If possible, Terminal Modules and Sensor Modules of direct measuring systems should

Connecting the motor encoder via DRIVE-CLiQ:
– Single Motor Module Booksize to terminal X202
– Double Motor Module Booksize motor X1 to terminal X202 and motor X2 to terminal
X203
– Single Motor Module Chassis to terminal X402
– Power Module Blocksize with CUA31: Encoder to terminal X202
– Power Module blocksize with CU310-2: Encoder to terminal X100 or via TM31 to X501
– Power Module Chassis to terminal X402
Example: Do not connect 8 DRIVE-CLiQ nodes in series at one DRIVE-CLiQ socket of
the CU - but instead, connect 2 nodes at each of the 4 DRIVE-CLiQ sockets.
X200 on the first booksize power unit or X400 on the first chassis power unit.
the DRIVE-CLiQ sockets X201 to X200 and/or X401 to X400 on the follow-on component.

within a DRIVE-CLiQ line (e.g. Motor Modules wired in series), for example, one Sensor
Module or one Terminal Module, without routing to additional components.
not be connected to the DRIVE-CLiQ line of Motor Modules, but rather, to free DRIVE-
CLiQ sockets of the Control Unit.
Note: This restriction does not apply to star-type connections.
