Basic information about the drive system 12.12 System sampling times

5.For Active Line Modules (ALM) in booksize format, only a current controller sampling time of 125.0 µs or 250.0 µs can be set.

6.For ALMs in chassis format, only a current controller sampling time of 250.0 µs or

400.0µs / 375.0 µs (375 µs when p0092 = 1) can be set.

7.For Basic Line Modules (BLM), only a current controller sampling time of 2000 µs can be set.

8.For Motor Modules in chassis format, a current controller sampling time of minimum 250 µs can be set (250 µs ≤ p0115[0] ≤ 500 µs).

9.For Motor Modules in blocksize format (PM340), a current controller sampling time of

62.5µs, 125.0 µs, 250.0 µs, or 500.0 µs can be set (only pulse frequencies in multiples of 2 kHz permitted).

10.When a chassis unit is connected to a DQS, the smallest current controller sampling time must be at least 250 µs.

Example:

Mixture of chassis and booksize units on a DQS

11.A current controller sampling time between 62.5 µs and 250.0 µs can be set for servo drives (62.5 µs ≤ p0115[0] ≤ 250.0 µs).

12.A current controller sampling time between 250,0 µs and 500,0 µs can be set for servo drives (250,0 µs ≤ p0115[0] ≤ 500,0 µs).

13.For servo drives with a current controller sampling time of p0115[0] = 62.5 µs, the 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 another DQS)

–Blocksize: 1 servo with p0115[0] = 62.5 µs

–Booksize servo drives can be combined on one DQS with a servo with p0115[0] =

125.0µs, but with the same quantity framework.

–A DQ hub DMC20 cannot be operated on a DQS with servo drives with p0115[0] =

62.5µs but must be connected to a separate DQS.

14.Synchronous PROFIBUS operation (set p0092 to 1):

–Servo, vector and vector-V/f control objects must have the same current controller sampling time.

Exception: 125.0 µs can be mixed with 62,5 µs and 125.0 µs can be mixed with 250.0 µs.

–The current controller sampling time must also be a multiple integer of 125.0 µs or equal to 62.5 µs.

15.For vector and vector-V/f control drive types, and when using a sinusoidal filter (p0230 > 0), it is only permissible to change the current controller sampling time of the DO involved in multiple integer steps of the default value.

16.The following applies when using a Voltage Sensing Module (VSM): All current controller sampling times at the DQS must be the same.

17.For 3 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).
