Caution

If a Power Module Blocksize is connected to a Control Unit, the sampling times of all vector drives are set according to the rules for Power Modules Blocksize (only 250 µs or 500 µs possible).

12.12.5Examples when changing sampling times / pulse frequencies

Example: Changing the current controller sampling time from 62.5 µs with p0112

Preconditions:

●Maximum 2 drives, Booksize format

●Servo motor control type

Procedure:

1.p0009 = 3 (not for offline operation)

2.Switch to the first servo drive object

3.p0112 = 4

4.Switch to the second servo drive object and repeat step 3.

5.p0009 = 0 (not for offline operation)

6.When STARTER is in offline mode: Download into the drive.
