Basic information about the drive system
12.12 System sampling times and number of controllable drives
Example: Changing the pulse frequency with p0113
Requirements:
● STARTER is in the online mode.
Assumption:
● A TB30 has been installed.
● Drives in servo control
Procedure:
1. Make the setting p0009 = 3 in online mode.
2. Switch to the first "SERVO" drive object.
3. Make the setting p0112 = 0.
4. Enter the required minimum pulse frequency via parameter p0113.
5. Switch to the second "SERVO" drive object and repeat steps 3 and 4.
6. Switch to the "TB30" drive object.
7. Set the three sampling times p4099[0..2] to a multiple of the current controller sampling
8. Make the setting p0009 = 0.
9. Perform "Copy RAM to ROM" to retentively save the parameter changes (see also the
10. Then start the recalculation of the controller settings (p0340 = 4).

If this pulse frequency contradicts rule 1 for setting the sampling times, an alarm is output
and a suitable pulse frequency is recommended in p0114. The current controller
sampling times of the drive objects (DOs) and the sampling time of the inputs/outputs of
the Control Unit, TM and TB modules must be a multiple integer of 125 µs. This can be
entered in p0113 (remember to take into account the rules for setting the sampling times).
time of a SERVO drive.
The pulse frequency in p1800 is automatically adapted.
