● The sampling times (p0115[0] and p4099) of all components that are connected to a DRIVE-
CLiQ line 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 DRIVE-CLiQ line, the following options are available:
– Reconnect the DO to a separate DRIVE-CLiQ line.
– Also change the current controller sampling time and the sampling time of the inputs/
outputs of the DO not involved so that they again fit into the time grid.
Note
A Double Motor Module, a DMC20, and a TM54F each correspond to two DRIVE-CLiQ
nodes. This also applies to Double Motor Modules, of which just one drive is configured.
To enable the function "Automatic configuration" to assign the encoders to the drives, the
recommended rules below must be observed.
Recommended rules
● The DRIVE-CLiQ cable from the Control Unit must be connected as follows:
– To X200 of the first booksize power unit
– To X400 of the first chassis power unit
● The DRIVE-CLiQ connections between the power units must each be connected from
interface X201 to X200 or from X401 to X400 on the follow-on component.
