7.6.1 Permissible combinations: Line Module and Motor Module
With the exception of the Line Module, all components on a DRIVE-CLiQ line must
have the same sampling time.
The following table shows the permissible sampling times of other nodes on a
DRIVE-CLiQ line for a Line Module.
Table 7-9 Permissible sampling times on a DRIVE-CLiQ line
Line Module
Motor Module
125 µs (booksize) and 250 µs 125 µs (booksize only) and 250 µs
400 µs 400 µs
2 ms 250 µs and 400 µs
The sampling times are set automatically as follows:
S Active Line Module (booksize): 250 µs
S Active Line Module (chassis):
– 400 V ;  300 kW / 490 A: 250 µs
– 400 V ; > 300 kW / 490 A: 400 µs
– 690 V ;  330 kW / 310 A: 250 µs
– 690 V ; > 330 kW / 310 A: 400 µs
