1.5 Rules for wiring with DRIVE-CLiQ
The following combinations are permissible for current controller cycle mixed operation:
● Servo control with 125 µs and servo control with 250 µs (max. 2 clock cycle levels can be
● Servo control with 62.5 µs and servo control with 125 µs (max. 2 clock cycle levels can be
Note the following: 1 axis with 31.25 µs corresponds to
● 2 servo control axes with 62.5 µs
● 4 servo control axes with 125 µs
● 8 U/f control axes with 500 µs
Cycle times for vector control
This following table lists the number of axes that can be operated with a Control Unit in the
vector control mode. The number of axes is also dependent on the cycle times of the
controller:

250 µs 1000 µs
Valid for TM31 or TM15IO; for TM54F, TM41, TM15, TM17, TM120, TM150 - restrictions are possible dependent on the

set sampling time.
For power units in chassis format, the infeed cycle depends on the power rating of the module and can be 400 μs, 375
2)
μs or 250 μs.
This setting results in lower remaining computation times.
3)
In closed-loop vector control, current controller cycles can be mixed with 250 µs and 500 µs.
Note
Restriction for the chassis format
If edge modulation and wobbling are activated simultaneously with p1802 ≥ 7 and p1810.2 =
1 respectively, the quantity structure for vector control is halved. Then a maximum of 3 axes
at a current control cycle of 500 µs, 2 axes at 400 µs or 1 axis at 250 µs are permissible.
