following applies:
– Only possible in booksize and blocksize format.
Maximum number of components/devices:
– Booksize: Two servo with p0115[0] = 62.5 µs + Line Module (connected to a different
DRIVE-CLiQ line)
– Blocksize: One servo with p0115[0] = 62.5 µs
– Booksize SERVO drives can be combined on one DRIVE-CLiQ line with a servo with
p0115[0] = 125.0 µs (but with same quantity framework).
– The current controller sampling time must be a multiple of 125.0 µs, 62.5 µs or
31.25μs.
is only permissible to change the current controller sampling time of the DO involved in
multiple integer steps of the default value.
– For three drives in vector control (speed control: r0108.2 = 1), a minimum current
controller sampling time of 250.0 µs can be set
(250.0 µs ≤ p0115[0] ≤ 500 µs).
This rule also applies to parallel connection of up to four Motor Modules.
– For four vector drives (speed control: r0108.2 = 1), a minimum current controller
sampling time of 375.0 µs can be set
(375.0 µs ≤ p0115[0] ≤ 500 µs).
Note
Restriction of the number of axes for chassis in vector control
For active edge modulation and active wobbling, only half the number of axes is
permissible.
possible (ALM, TB and TM additionally possible).
sampling times are not integer multiples of one another.
Example 1:
At Control Unit X100: Active Line Module with 250 µs
At Control Unit X101: One VECTOR drive object with 455 µs (p0113 = 1.098 kHz)
This setting is permissible.
Other DRIVE-CLiQ lines must have a minimum sampling time of 250 µs or 455 µs.
