Basic information about the drive system
12.13 System sampling times
19. When servo is operated together with vector V/f control, a maximum of 5 DOs is possible
20. A maximum of two DRIVE-CLiQ lines are possible in the unit where the lowest sampling

(ALM, TB and TM additionally possible):
Examples:
– 1 servo + 4 vector V/f control with current controller sampling time 400 µs ≤ p0115[0] ≤
500 µs
– 2 servo + 3 vector V/f control with current controller sampling time 400 µs ≤ p0115[0] ≤
500 µs
– 3 servo + 2 vector V/f control with current controller sampling time 250 µs ≤ p0115[0] ≤
500 µs
– 4 servo + 1 vector V/f control with current controller sampling time 250 µs ≤ p0115[0] ≤
500 µs
times are not integer multiples of one another.
Example 1:
At CU-X100: Active Line Module with 250 µs
At CU-X101: 1 vector drive object with 455 µs (p0113=1.098 kHz)
This setting is allowed.
Other DRIVE-CLiQ lines must have a minimum sampling time of 250 µs or 455 µs.
