● A maximum of 9 encoders (measuring systems) can be connected to a PPU/NX.
● Sensor Modules:
Rules for DRIVE-CLiQ wiring using a DMC20 without NX
● If 6 drive units are operated on one DRIVE-CLiQ line, DMC20 must be operated on a
● If 5 drive units are operated on one DRIVE-CLiQ line, DMC20 can be operated on the last
Rules for DRIVE-CLiQ sockets
The following rules must be observed when using DRIVE-CLiQ sockets:
● The DRIVE-CLiQ cable between the PPU and the Line Module must be connected to
● The DRIVE-CLiQ cables between the power units should be connected from interface
● The power line to the motor and the associated motor encoder must be connected to a

– SMC/SME modules can be connected to the final Motor Module.
– SMC modules can also be connected to the PPU.
– Connect additional measuring systems via DMC20.
Note
Connecting a direct measuring system to a free DRIVE-CLiQ socket from SLM/ALM is
not advised as differing cycle rates can lead to differing dynamic behavior from the
interpolating machine axes.
Only the encoders connected to the same DRIVE-CLiQ line as the relevant servo
drive can be evaluated.

– Motor connection X1: Encoder at X202
– Motor connection X2: Encoder at X203
Note
If an additional encoder is connected to X201 of a Double Motor Module, it is
automatically assigned to the second motor as encoder 2.
