– 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

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.
CLiQ connections with a sampling time of T
The following components are permissible:
– Sensor Modules
– High-frequency damping modules (HF damping modules)
– Active Line Modules Booksize in the line of the HF filter module.
– Smart Line Modules Booksize in the line of the HF filter module.
– Additional DRIVE-CLiQ lines must be used for further components:
Further Motor Modules in servo control, in vector control, in U/f control or TMs.
