(22)Joystick function:
If enable, the controller can drive the motor on two directions without using any reversing
switch.
Just one single throttle can drive the motor on forward and reversing direction.
The stick shift throttle firmware can be called wig-wag or joystick operation. It is only a software
function. Usually It is useful for electric boat project. You still can use the common 0-5K pot or
0-5V throttle for the controller. If you don't choose the joystick, you operated the throttle in this
way. The motor speed will increase when the throttle is from 0V to 5V.
If you enable joystick for this controller in user program, you will start the motor from 2.5V
position.2.6V to 5V is forward.2.4V to 0V is backward.
2.4V to 2.6V is the throttle dead zone. Customers can adjust the throttle dead zone in user
program also.
Please note the common throttle will spring back to original position if you release the throttle.
Suggestion: factory default is Disable.
