If the controller is operating when the reversing switch is changed, the controller will automatically slow down at a rate determined by the decel ramp adjustment to zero speed. It will then reverse the motor (this may require the speed to be turned to zero) and accelerate to full speed, rate determined by the acceleration ramp.
This enables the top speed to be reduced, e.g. in a child's car where the child is too young to use the full speed range. It also allows the controller to be matched to various throttle devices (e.g. foot-pedal, Bell throttle, twist-grip throttle) and supply voltages.
A joystick (aka Wig-Wag control) is a lever operated speed and direction control. Move the lever forward to go forward, and pull it back to go backwards. The speed is controlled by how far forward (or back) you pull the lever.
Describes the state of the connection between the controllers motor terminals when no power is applied. This will affect the amount of regenerative braking experienced when trying to push or tow a vehicle.
In this mode, operating the reverse switch whilst the controller is operating has no effect. If the reverse switch is operated and the speed is manually reduced to zero, then the controller will start up in the pre-selected direction.
Controls the rate at which the controller will speed up or slow down. Slow rates are useful on locos and childrens vehicles, fast rates are useful for robots and some industrial machines.
