Vector Mode fully Stable

Due to a series of straight out mistakes I actually didn't have the shaft encoder wired up correctly.
Last night I wired it up properly, enabled it and ran the motor flawlessly in Vector mode.
Now to put in my configuration for accelerator control. I guess I'd better build the mount for the accelerator pedal sometime soon.

Later edit (so I have these documented somewhere).
The motor values I entered into the controller for were:
22kW, 2960 RPM, 100 Hz, 41.3A, 440 V, 0.78 cos theta.
Param  Value
22     88.5 Motor MaxA
23     50 Gen MaxA
81     22 kW
87     2960 RPM
88     41.3 Nom. A
89     100 Hz
90     440 V
91     0.78


Which resulted in the controller's auto-tune setting these values:
Param  Value
82     0.044
84     97.77
85     0.9
92     17.8
