Figure 12-22 Example: DRIVE-CLiQ line on a CU320 X103
● Only one Line Module (or if connected in parallel, several) can be connected to a Control
Unit.
● If using Chassis design components, no more than one Smart Line Module and one
Basic Line Module may be jointly operated on one Control Unit (mixed operation on a
DRIVE-CLiQ line).
● The default sampling times may be changed.
● Mixed operation of servo and vector is not permitted.
● Mixed operation (servo with vector V/f) is possible.
● During mixed operation of servo and vector V/f, separate DRIVE-CLiQ lines must be used
for Motor Modules (mixed operation is not permissible on Double Motor Modules).
● With vector V/f control, more than four nodes can only be connected to one DRIVE-CLiQ
line on the Control Unit.
● 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)
– can be connected to one DRIVE-CLiQ line in servo mode.
– must be connected to separate DRIVE-CLiQ lines in vector mode.
● The Line Module (chassis) (ALM, BLM, SLM) and the Motor Modules (chassis) must be
connected to separate DRIVE-CLiQ lines.
● Motor Modules (chassis) with different pulse frequencies must be connected to separate
DRIVE-CLiQ lines. For this reason, chassis Motor Modules and booksize Motor Modules
must be connected to separate DRIVE-CLiQ lines.
● The Voltage Sensing Module (VSM) should be connected to a free DRIVE-CLiQ port of
the Active Line Module (due to the automatic assignment of the VSM).
● The sampling times (p0115[0] and p4099) of all components that are connected to a
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.
