Voltage regulator in the field converter

!
In the most of the cases the DC motors with an independent excitation operate with a direct
field (
Flux reg mode=Constant current
). In this case it is not necessary to optimize the
regulator of the armature voltage.
When a Voltage control occurs, the voltage regulator keeps the armature voltage at a constant level. The most
difficult moment for this regulator is the beginning of the Voltage control, because due to the saturation of the
motor field, the flux variation requires quicker changes of the field current.
Tune the regulator in order to have small changes of the armature voltage.

All the other converter regulators must be set before the optimization of the voltage regulator.
- Drive disabled = no voltage on terminal 12
- Choose the following settings for the Test generator :
-
Gen access
=
Ramp ref
-
Gen frequency
=
0.2 Hz
-
Gen amplitude
=
10 %
-
Gen offset
=
according to the changing point from the armature regulation
to the field one. Example:
Motor max speed
= 2000 rpm,
the Voltage control starts at 1500 rpm.
Gen offset
= 75 %
- Measure the field current and the armature voltage on an analog output. The “Flux current” and the “Output
voltage” variables must be set on two different analog outputs (see Programming “Inputs/Outputs).
- Enable the drive and give the Start command (voltage on the terminals 12 and 13)
- Check the armature voltage. After a possible short jump, the voltage should remain constant. See figures
5.3.6.8 ... 5.3.6.10. In the REG PARAMETER /... menu, it is possible to change the P and I section with
the
Voltage P
and
Voltage I
parameters.
- Stop and disable the drive.
- Gen access = Not connected
- Save the settings.
Figure 5.3.6.8: Above: Flux; Below: Output voltage. After a speed change the
field current (Flux) has some jumps. Voltage P = 10%, Voltage I = 80%.
Figure 5.3.6.9: Above: Flux; Below: Output voltage. The gain is too low. The
armature voltage increases. Voltage P = 3%, Voltage I = 5%.
