Note
Vector drives in chassis format can also be operated with a current controller sampling time
of 400 µs (amongst other settings).
In the SIMOTION context, the following should be considered:
● A current controller sampling time of 400 µs is only possible if control is via a
● If the bus is operated isochronously, only cycle clocks with an integer multiple of 125 µs
● The PROFIBUS Integrated of a D4x5-2/CX32-2 is always isochronous! This means that a
● With CU parameter p0092 = 1, the sampling times are pre-assigned so that isochronous
Scenario 2: Current and speed controller cycle is not known
This procedure is especially suitable for devices in chassis format, as the current and speed
controller cycle also depends on the relevant device type.
