11.2: Current Loop Auto Tune
Tune the Current Loop with Auto Tune
METHOD: The current loop Auto Tune algorithm applies a square-wave command to the
current loop and adjusts current loop proportional gain (Cp) and current loop integral
gain (Ci) until a desirable waveform is obtained.
Initial current loop proportional gain (Cp) and current loop integral gain (Ci) values can
be calculated with The Calculate Function (p. 54).
Click I Loop to open the Current Loop screen:
Verify that the amplifier is hardware enabled.
Click Auto Tune to open screen and start the Current Loop Auto Tune.
To Change the Auto Tune Current, Press Stop, enter the new current in the Auto Tune
Current field, and then press Start.
