Mixed operation of vector control and V/f open-loop control
In mixed operation with vector control and V/f control, one axis in vector control at 250 µs
uses exactly as much computing power as two axes in V/f control at 500 µs. In conjunction
with vector control, a maximum of 11 axes are permitted (1 vector control plus 10 V/f
control).

Valid for TM15, TM17 or TM41; for TM54F, TM31, TM120, TM150 - restrictions are possible dependent on the set
sampling time.
2)
DQ = DRIVE-CLiQ
If the 310-2 Control Unit is snapped on to a PM340 or a PM240-2 FS A-C, a minimum
current controller sampling time of 62.5 µs is possible. For PM240-2 FS D-F the minimum
current controller sampling time is 125 µs.
Using DCC
The available remaining computation time can be used for DCC. In this case, the following
supplementary conditions apply:
For a 2 ms time slice, a max. of 75 DCC blocks can be configured for each servo control
axis with 125 μs that can be omitted/eliminated (≙ 2 V/f axes with 500 μs).
50 DCC blocks for 2 ms time slice correspond to 1.5 V/f axes with 500 μs.
Detailed information about handling and using DCC standard blocks is provided in the
"SINAMICS/SIMOTION Editor Description DCC" manual.
