Advanced commissioning
6.18 PID technology controller
Autotune the PID controller
Requirements
The PID technology controller must be set the same as when used in subsequent operation:
● The actual value is interconnected.
● Scalings, filter and ramp-function generator have been set.
● The PID technology controller is enabled (p2200 = 1 signal)
Procedure
Proceed as follows to auto tune the PID controller:
1. Select with p2350 the appropriate controller setting.
2. Switch on the motor.
The inverter signals Alarm A07444.
3. Wait until alarm A07444 goes away.
The inverter has recalculated parameters p2280, p2274 and p2285.
If the inverter 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.
