1.4.5 Manual Tunings of Regulator Loops (Test Generator)
The automatic loops tuning (CurrentReg, FluxReg and SpeedReg autotune) is strongly recommended before to
carry out any manual tuning. The manual tunings can be useful to improve the response time of the drive loops.
Using the Test generator function it is possible to carry out the manual tunings.
In the following paragraphs it is described the procedure:
- Manual tuning of the Current regulator
- Manual tuning of the Flux regulator
- Manual tuning of the Speed regulator
1.4.5.1 Test Generator Function
The tuning of the regulators is performed via an internal test signal generator in order to evaluate the regulator
response. This operation requires the use of a digital oscilloscope. The “Test generator” generates signal shaped
as a rectangular wave with a programmable frequency and amplitude.
For each tuning, described in the following= pararagraphs, follow the steps below.
In the REGULATION PARAM menu, scroll
Down until Test generator command, then press Enter.
The display will show: Test generator
Test gen mode press
Enter.
The display will show: Test gen mode
Off press
Enter.
The display will show: Select new mode
Off press
Enter and scroll Down to select the regulator
input on which the signal must work(see procedures):
Off off
Ramp ref 1 Ramp reference 1
Speed ref 1 Speed reference 1
Torque ref 2 Torque reference 2
Magn curr ref Magnetizzant current reference
Flux ref Flux reference
Outvlt lim Voltage reference
then press
Enter and wait for the end of “Busy - Please wait....”message.
Press
Escape two times to return Test gen mode menu.
Scroll
Down to: Test generator
Test gen cfg press
Enter.
Set the following parameters:
Gen hi ref Value in count of the higher value
Gen low ref Value in count of the lower value
Gen period Period of the square wave
