Basic information about the drive system
12.12 System sampling times and number of controllable drives
5. For Active Line Modules (ALM) in chassis format, only a current controller sampling time
6. For Basic Line Modules (BLM), only a current controller sampling time of 2000 µs can be
7. For Motor Modules in chassis format, a current controller sampling time of minimum 125
8. For Motor Modules in blocksize format, a current controller sampling time of 62.5 µs,
9. When a chassis unit is connected to a DRIVE-CLiQ line, the smallest current controller
10. A current controller sampling time between 31.25 µs and 250.0 µs can be set for servo
11. A current controller sampling time between 125.0 µs and 500.0 µs can be set for servo
12. For servo drives with a current controller sampling time of p0115[0] = 62.5 µs, the

set.
µs can be set (125 µs ≤ p0115[0] ≤ 500 µs). This applies to the Servo and Vector control
types.
125.0 µs, 250.0 µs, or 500.0 µs can be set (only pulse frequencies in multiples of 2 kHz
permitted).
sampling time must be at least 125 µs. This applies only to the Servo control type.
Example:
Mixture of chassis and booksize units on a DRIVE-CLiQ line.
drives (31.25 µs ≤ p0115[0] ≤ 250.0 µs).
drives (125.0 µs ≤ p0115[0] ≤ 500.0 µs).
following applies:
– Only possible in booksize and blocksize format.
Maximum number of components/devices:
– Booksize: 2 servo with p0115[0] = 62.5 µs + Line Module (connected to a different
DRIVE-CLiQ line)
– Blocksize: 1 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.
