This rule also applies for parallel connection (3 or 4 Motor Modules connected in parallel)
18. For 4 vector drives (speed control: r0108.2 = 1), a minimum current controller sampling
time of 400.0 µs can be set
(400.0 µs ≤ p0115[0] ≤ 500 µs).
19. When servo is operated together with vector-V/f, a maximum of 5 DOs is possible (ALM,
TB and TM additionally possible):
Examples:
– 1 servo + 4 vector-V/f (vector-V/f: 400 µs ≤ p0115[0] ≤ 500 µs)
– 2 servo + 3 vector-V/f (vector-V/f: 400 µs ≤ p0115[0] ≤ 500 µs)
– 3 servo + 2 vector-V/f (vector-V/f: 250 µs ≤ p0115[0] ≤ 500 µs)
– 4 servo + 1 vector-V/f (vector-V/f: 250 µs ≤ p0115[0] ≤ 500 µs)
20. A maximum of two DRIVE-CLiQ lines are possible in the unit where the lowest sampling
times are not integer multiples of one another.
Example 1:
At CU-X100: ALM with 250 µs
At CU-X101: 1 vector drive object with 455 µs (p0113=1.098 kHz)
This setting is allowed.
Other DQS must have minimum sampling time of 250 µs or 455 µs.
12.12.4 Default settings for the sampling times
When commissioning for the first time, the current controller sampling times (p0115[0]) are
automatically pre-set with these default values as follows:
