PID programming on ACS355

Hello, ABB.

I'm having trouble configuring a ACS355 drive for a PID control macro.

So far, I've configured all the parameters I've deemed necessary for it (Analong inputs, all the 40xx parameters and the basic ones for the motor configuration), but I've had no luck yet. I've also looked online but haven't found anything that could help me. One problem is that I'm doing it on a Standard Control Pad, which makes finding help harder.

Could anyone help or share with me a document explaining how to do this procedure?

Thanks a lot!

Hi

in addition to the good explanation of kstoilov, you can read my short suggested configuration of the drive in the attached doc.

Hope this help you

UPDATE:

I followed step-by-step the document you shared (it was really good); however, the output of the PID1 is still on 0. I have the motor running at the minimum frecuency I set on parameter 2007, but the control is not happening.

Any ideas on what I can do?

Could you measure the output of the sensor on the process? The complessive functioning of the drive could depending on other variables that I can not know... generally with the instruction that i gave you, the drive not have problem to operate..

I'm noticing that the parameter set for display 3415 is showing zero. From what I understand, that should be the setpoint I programmed on 4011, could this be the problem?

I'm receiving an accurate 4...20mA signal on EA2, as seen on parameter 0121.

I can give you one answer if you can post the complete set of parameter, but this require to add in my drive on laboratory your parameters set and test it... this is possible, but not in short time

I have the same parameters you have in the PDF, the only changes are:

MOTOR DATA
230V
20.5 A
5.5 kW
60 Hz
1730 rpm

PARAMETER CHANGES
2007 = 10Hz
4006 = 25
4007 = 1
4008 = 0
4009 = 250
4011 = 65

Hi,

Have you looked in ACS355 User's manual? It is always better to look in the manual and go trough the parameters manually.

Doesn't matter if you are using Standard Control Panel - you can modify all the parameters trough it.

Please describe what is you "trouble" - drive is not starting, PID is not working correctly...

May be the easiest way in your case is to select PID Macro in 99.02 and then use the predefined I/O's. Once you start the drive, you can modify the I/O's settings and other parameters according to your needs.

He drive is not starting. I think I'm having trouble with the 1xxx and 11xx parameters, not the 40xx ones.

What I could use is some sort of walk through these parameters in order to understand them better.

Hi,
First look on page 180:
If you have made changes to the parameter values and want to restore the default values, you must first select another macro (parameter 9902 APPLIC MACRO), save the change, select the original macro again and save. This restores the default parameter values of the original macro


By kstoilov on 4/18/2018 | Like (0) | Report

Then go trough parameters described on page 181. 1.xx parameters are read only.
Look 10.x, 11.x, 12.x, 13.x, 1.x, 16.x, 22.x, 32.x, 34.x, 99.4

10.01 Start and stop through digital input DI5. 0 = stop, 1 = start.
Means to start need DI5=1
11.02 means DI2=0 for EXT1 to be valid
12.01 means DI3=0 to deactivate fixed speed
16.01 means DI4=1 - THAT IS A MUST TO START THE DRIVE
Also check the bridge between terminals 10 and 11 on X1A


By daguilara9 on 4/18/2018 | Like (0) | Report

Do I need to have a signal connected to EA1? I'm having trouble understanding the function of the EXT1/REF1 functions.

Thanks! This clarifies and reassures many questions I had.
