just checked your link
the self learn shows green wire connected by one pin black connector, I'm not sure if those wires should be together to go into self learn mode, or disconnect for self learn mode. I'll check some directions i have for self learn controllers and post shortly,
My guess is: leave connected when first using with motor, find correct combination, when motor running smoothly from any position in correct direction, disconnect the green wires, it will remember the setting, no need to use green wires again, leave disconnected. ( it could be disconnect them to get self learn mode, but try my suggestion first, i'll check what other info I have)
with regards speed mode: its a three pin connector: brown/black/grey
they usually have three speed settings, but maybe this one has only two. My guess is, connect brown to black, for one speed limiting setting, leave disconnected for another speed setting, connect grey to black for third speed setting.
