Cycle times in the "vector" control mode
The following table shows the number of axes that can be operated depending on the
selected cycle times in the "vector" control mode:

1) Valid for TM31 or TM15IO; for TM54F, TM41, TM15, TM17, TM120 - restrictions are possible dependent on the set
sampling time.
2) For power units in chassis format, the infeed cycle depends on the power rating of the module and can assume values
of 400 μs, 375 μs or 250 μs.
3) This setting results in lower remaining computation times.
The following combination is permissible in current controller cycle mixed operation:
● Vector with 250 µs and vector with 500 µs

NOTICE
Restriction for chassis format in the case of special functions
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, for
example, 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 possible.
