Cycle times for vector control

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:
Table A- 6 Sampling time setting for vector control
Cycle times [µs]
Current con- Speed controller
troller
500 µs 2000 µs
400 µs 1600 µs
2)
250 µs 1000 µs
Valid for TM31 or TM15; for TM41, TM15, TM120, TM150 - restrictions are possible depending on the set sampling
1)
time.
This setting results in reduced remaining computation times.
2)
Adjustable pulse frequencies and current controller sampling times for vector control
The pulse frequencies that can be set depending on the selected current controller sampling
time are shown in r0114.
This means that maximum 2 cycle levels can be mixed.
