7. Save the parameter changes in a non-volatile fashion using the function "Copy RAM to

ROM" (see also the Commissioning Manual).

8. We recommend that the controller settings are re-calculated (p0340 = 4).

Example: Changing the pulse frequency with p0113

Preconditions:

● STARTER is in the online mode.

Assumption:

● A TB30 has been installed.
● Servo motor control type

Procedure:

1. p0009 = 3 (not for offline operation)
2. Switch to the first servo drive object
3. p0112 = 0
4. Enter the required minimum pulse frequency in p0113.

If this conflicts with rule 1 for setting the sampling times ("The current controller sampling

times of the drive objects (DOs) and the sampling times of the inputs/outputs of the

Control Unit, TM, and TB modules must be an integer multiple of 1.25 µs."), an alarm is

output and a suitable pulse frequency is proposed in p0114. This can be entered in

p0113 (remember to take into account the rules for setting the sampling times).

5. Switch to the second servo drive object and repeat steps 3 and 4.
6. Change into the drive object TB30
7. Set the three sampling times p4099[0..2] to a multiple of the current controller sampling

time of a servo drive.

8. p0009 = 0

Note: The pulse frequency in p1800 is automatically adapted.

9. Save the parameter changes in a non-volatile fashion using the function "Copy RAM to

ROM" (see also the Commissioning Manual).

10. We recommend that the controller settings are re-calculated (p0340 = 4).
