May 12 1997 09:26:11:470AM970512003Steve WolfeChecking on the cross-talk issue: loaded a model with the EF1U&L P and I gains set to zero.

Supposed to be a EF1 PLC test.
Result - no supply fired
Cross talk down by about a factor of 2. Saturated channels are EF2's and EF4.
May 12 1997 10:03:20:380AM970512006Steve WolfeShot 6:
Set up to double swing EF1's. Normal initial rise to -4800A, reverse swing to 2000A.
No commutation.
P gain only, set at 2.0

Looks good. Voltage follows demand (mostly).
Small bursts of oscillations at -1.1 to -1.0, and neat peak voltage ~+.370sec
May 12 1997 10:04:59:740AM970512007Steve WolfeShot 7:
Same as 6, but with commutation.

Looks about the same.
May 12 1997 10:46:22:500AM970512009Steve WolfeShot 9: TF only
No current: Forgot to write the control screen
May 12 1997 10:55:44:470AM970512009Steve WolfeShot 10: TF only - try again

TF rogowski screwed up - looks like a bad integrator gate.
Gas burst starts around 0.6 sec.
