[Dsg-hallc_controls] Current regulation loop

[Mike Fowler]

Hi,

It appears that your expectation is not correct.
I stopped reviewing the code when I found the following.

Issues found:

Rung 0
The MPS_WA_Value will always be greater than ADC_Readback_MPS

The WA value is the PSU set value 0 to 100% or 0 to 999999
The readback value is always a factor of 10 less.

Rung 2
I_MOL is the current set value 0 to 3000 amps., it will never match the ADC readback.

Unknown, possible runaway, condition when there is an interlock, the PSU ramps down, operator resets the interlock, and restarts.

Cheers,
Mike

Hello Steve and Mike,

Updated versions of the HMS and SHMS programs to include the current regulation loop are in the M: drive, "M:\dsg-hallc_controls\HMS_Controls_V20_current_loop.ACD" and "M:\dsg-hallc_controls\SHMS_V_20_current_loop.ACD". The program was tested using the DSG test PLC and a serial program to simulate the danfysik power supply. The program ran as expected and allowed the user to change setpoints mid-ramp without issue. 

Regards,
Amanda
