1.5 Rules for wiring with DRIVE-CLiQ
● The maximum number of DRIVE-CLiQ nodes on a DRIVE-CLiQ line of the Control Unit
● The maximum number of DRIVE-CLiQ nodes on a DRIVE-CLiQ line of the Control Unit
● Examples, CU320-2 with 62.5 µs sampling time:
● Example, CU320-2 with 31.25 µs sampling time:
● If the current controller sampling time T

320-2 depends on the basic clock cycle of the DRIVE-CLiQ line:
– For a current controller cycle of 31.25 µs, a maximum of 3 DRIVE-CLiQ nodes are
permissible
– For a current controller cycle of 62.5 µs, a maximum of 5 DRIVE-CLiQ nodes are
permissible
– For a current controller cycle of 125 µs, a maximum of 14 DRIVE-CLiQ nodes are
permissible
– For a current controller cycle of 250 µs, a maximum of 20 DRIVE-CLiQ nodes are
permissible
– For a current controller cycle of 500 µs, a maximum of 30 DRIVE-CLiQ nodes are
permissible
310-2 depends on the basic clock cycle of the DRIVE-CLiQ line:
– From a current controller cycle of 125 µs, a maximum of 8 DRIVE-CLiQ nodes are
permissible

sampling time that does not match the other drive objects in the DRIVE-CLiQ line, the
following solutions are available:
– Insert the modified drive object into a separate DRIVE-CLiQ line.
– Modify the current controller sampling times and/or the sampling times of the
inputs/outputs of the other drive objects in the same way, so that they match the
modified sampling time again.
