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).
12.12.5 Examples 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.
