28. The maximum number of DRIVE-CLiQ nodes on a DRIVE-CLiQ line of the Control Unit
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
29. Examples for clock cycle level 62.5 µs:
– Topology 1: 1 x ALM (250 µs) + 2 x servo (62.5 µs) + 2 x servo (125 µs) + 3 x TM15 +
TM54F + 4 x dbSI2 with encoder SI Motion monitoring clock cycle (p9500) = 12 ms +
SI Motion actual value sensing clock cycle (p9511) = 4 ms + 4 x dir. measuring
systems
– Topology 2: 1 x ALM (250 µs) + 2 x servo (62.5 µs) + 2 x U/f (500 µs) + 3 x TM15
Base 2 ms +2 x dbSI2 with encoder SI Motion monitoring clock cycle (p9500) = 12 ms
+ SI Motion actual value sensing clock cycle (p9511) = 4 ms + 2 x dbSI2 sensorless +
2 x dir. measuring systems
– Topology 3: 1 x servo (62.5 μs) + 4 x U/f is not possible in connection with Safety
Integrated.
30. Examples for clock cycle level 31.25 µs: 1 x servo (31.25 µs)
31. If the current controller sampling time T
i
at one drive object has to be changed in a
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.
32. Only components that have the same sampling time may be be connected to free DRIVE-
CLiQ connections with a sampling time of T
i
= 31.25 μs.
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.
