A.3 Supported sample topologies
Sampling time 31.25 µs
Examples, CU320-2 with 31.25 µs sampling time:
● Topology 1:
1 ALM (250 μs) on a line, 1 servo (31.25 μs) on a line, 3 TM15 Base (p4099[0] = 2000 µs)
on a line and in series.
● Topology 2:
1 ALM (250 μs) on a line, 1 servo (31.25 μs) on a line, 1 direct measuring system on a line.
Topology example: Drives in U/f control (vector)
The following diagram shows the maximum number of controllable vector U/f drives with
additional components. The sampling times of individual system components are:
● Active Line Module: p0115[0] = 250 µs
● Motor Modules: p0115[0] = 500 µs
● Terminal Module/Terminal Board p4099 = 2 ms
