JonFreeman 4:67478861c670 7 5" and 7.25" gauge Electric Locomotive Controller - ST DISCO-F746NG
JonFreeman 4:67478861c670 8 Uses built in display and touch screen.
JonFreeman 4:67478861c670 9
JonFreeman 4:67478861c670 10 Display shows 'analogue' moving coil meter movements for :
JonFreeman 4:67478861c670 11 Locomotive speed Miles per Hour
JonFreeman 12:a25bdf135348 12 System voltage (range 10v - 63v or thereabouts)
JonFreeman 12:a25bdf135348 13 Power Watts delivered to drive motors or dumped.
JonFreeman 4:67478861c670 14
JonFreeman 12:a25bdf135348 15 Touch screen has three 'buttons', and are where the meter movements show.
JonFreeman 12:a25bdf135348 16 Two smaller meter buttons for two horns, larger speedo button currently unsused
JonFreeman 4:67478861c670 17
JonFreeman 4:67478861c670 18 Display has 'slider' touch control. This drives the loco.
JonFreeman 4:67478861c670 19 Control in central position when not driving or drfting.
JonFreeman 4:67478861c670 20 Moving towards bottom of screen applies regenerative braking - move further down applies harder braking.
JonFreeman 4:67478861c670 21 Moving towards top of screen powers drive motors, move further up applies more torque (current controller implemented)
JonFreeman 4:67478861c670 22 Take finger off and control drifts down to central 'neutral' position.
