1.5 Rules for wiring with DRIVE-CLiQ
● Mixed operation of servo and vector is not permitted.
● Mixed operation of servo with vector V/f is possible.
● During mixed operation of servo and vector V/f, separate DRIVE-CLiQ lines must be used
● With vector V/f control, more than four nodes can only be connected to one DRIVE-CLiQ
● A maximum of 9 encoders can be connected.
● A maximum of 8 Terminal Modules can be connected.
● The Active Line Module (booksize) and Motor Modules (booksize)
● The Line Module (chassis) (ALM, BLM, SLM) and the Motor Modules (chassis) must be
● Motor Modules (chassis) with different pulse frequencies must be connected to separate
● The Voltage Sensing Module (VSM) should be connected to a free DRIVE-CLiQ port of

● The DRIVE-CLiQ cable from the Control Unit must be connected to X200 on the first
● The DRIVE-CLiQ connections between the power sections must each be connected from
● A Power Module with the CUA31 should be connected to the end of the DRIVE-CLiQ line.

the Active Line Module (due to the automatic assignment of the VSM).
DRIVE-CLiQ line (DQS) must be divisible by one another with an integer result. If the
current controller sampling time on a DO has to be changed to another pattern that does
not match the other DOs on the DQS, the following options are available:
– Change over the DO to another, separate DQS.
– Also change the current controller sampling time and the sampling time of the
inputs/outputs of the DOs not involved so that they again fit into the time grid.
Note
You can call up the "Topology" screen in STARTER to change and/or check the
DRIVE-CLiQ topology for each drive unit.
Note
To enable the function "Automatic configuration" to assign the encoders to the drive,
the recommended rules below must be observed.
