3 - Setup Throttle In
Preview line shows measured voltage of throttle input, the equivalent % throttle that this voltage corresponds to, and the throttle mode (amps, speed, pass-thru, etc.)
Cntrl Mode: Allows you to select the function of the user's input throttle. Your Fat Woody has been configured for Pass-Thru throttle mode operation.
Pass-Thru: User throttle is linearly remapped from the input throttle range to the output throttle range, and then passed on to the output.
Current (A): User throttle controls the battery current, from 0A up to the value in the Max Current. If using this mode, it makes sense to have your CA's Max Current equal to or lower than the controller's current limit, otherwise only part of the range will be mapped.
Speed (kph): User throttle directly controls the speed of the bike, from 0 up to the value in Max Speed. This is not a recommended throttle mode for most scenarios as small twitches in the throttle can result in large pulses of power as the bike attempts to track this.
Power (W): User throttle controls the power to the motor controller, from 0 up to the value in Max Power. In this mode, you should not have your Max Power set much higher than your battery voltage times the controller current limit.
Off ( 0V ): This mode ignores the input throttle, and sets the output throttle signal low. The output can then only go high if you have one of the PAS modes enabled and are pedaling. You can achieve the same thing by simply unplugging the throttle, but this option can be useful if you want to swap between different presets with and without throttle modes.
Off (WOT): User throttle is ignored as well, the the CA's output will default to Max Throttle until one of the limits is exceeded. This is included for legacy support for people using a V3 CA on a controller designed for V2 CA-DP connector, which have a separate throttle feeding the controller and the CA is diode connected to only pull that signal down. If this mode is selected with the CA's output going directly to a CA3 compatible controller, then it will cause the bike to take off on power up. So be careful.
Min Input: This is the voltage threshold for the lower bounds of the input throttle. When the throttle signal is less than this, then it is assumed the throttle is off. It should be set at least 0.2V higher than the voltage present on the throttle when the throttle is disengaged. If it is set very close to your actual minimum voltage signal and you have one of the PAS modes enabled, then electrical noise can cause the CA to briefly assume that you are using the throttle which will disable the PAS output, resulting in a momentary drop in power.
Max Input: This sets the upper bound that is considered the 'full throttle' voltage. It is possible to play with this voltage to adjust your throttle range and sensitivity, but normally it would be set about 0.2V lower than your actual full throttle voltage.
Fault Volt: This sets a fault detection threshold. If the throttle signal is higher than the Fault Volt, the CA will assume there is a fault and not treat it as full throttle. This situation can happen for instance if the throttle's ground wire gets disconnected while the 5V and Signal lines are still connected. You would usually want this about 0.1V higher than you actual full throttle voltage.
Auto Cruis: This feature enables you to have a cruise mode if you hold the throttle steady in the same position for a length of time. At that point, the throttle slide on the first (Main) screen will start to flash. You can release the throttle but the CA will still maintain that throttle setting. The cruise mode is released anytime you hit the e-brakes or operate the throttle again.
Off: Auto Cruise Mode is Disabled.
2 Sec - 8 Sec: Auto Cruise will latch after holding throttle for (x) seconds.
Important Note: Your Fat Woody has been designed with a 'push button' cruise control connected to the controller (not the CA). Auto Cruise is disabled (turned OFF) on the CA. DO NOT enable this feature without discussing with Fat Woody, or there could be a conflict in e-bike operation that could be potentially dangerous.
Cruise Hld: This setting lets you adjust adjust the voltage sensitivity for the auto cruise throttle latch. If you have twitchy thumb throttle, then you may need to have a large voltage band. Too large of a band can cause the auto cruise feature to latch inadvertently even when you didn't want it.
