Executing Autotuning; Example For Speed Setpoint And Actual Process Value For Autotuning - Siemens SINAMICS G120XA Operating Instructions Manual

Figure 6-47
The converter calculates the parameters of the PID controller from the determined oscillation
frequency.

Executing autotuning

1. Select with p2350 the appropriate controller setting.
2. Switch on the motor.
The converter signals Alarm A07444.
3. Wait until alarm A07444 goes away.
The converter has recalculated parameters p2280, p2274 and p2285.
If the converter signals fault F07445:
– If possible, double p2354 and p2355.
– Repeat the autotuning with the changed parameters.
4. Back up the calculated values so that they are protected against power failure, e.g. using the
BOP‑2: OPTIONS → RAM‑ROM.
You have auto tuned the PID controller.
