Boost function is just full throttle position when you turn on boost switch even if the throttle is not
operated at all.
The boost function is still based on limiting of the motor current and battery current settings in
user program.
If disabled,the controller can provide brake sensor regen mode on the same pin as pin2.In
simple,boost and brake analog regen used the same pin as pin2.
Suggestion: Set according to the practical situation, factory default is Disable.So the default
function is brake variable regen mode.
(25)Foot switch:It is used for microswitch.If enabled,the controller will only accept the throttle
signal after received the valid foot switch signal.
If there is no foot switch signal,the controller will ignore the throttle signal.
Suggestion: Set according to the practical situation, factory default is Disable.
(26)Cruise Control:Value range: Enable and Disable
If enable,if you hold throttle at certain position about 5 seconds,the controller will get into Cruise
control.The Cruise function can not be activated in reversing direction.If the motor speed is
below 500RPM,the Cruise control can not be activated.
Release throttle and turn the throttle again or turn on the brake switch will make the Cruise
control quit.
Suggestion:factory default is Disable.
(27)Anti-Slip:
If enabled,the controller will try to prevent the vehicle rolling back on downhill faster and faster.If
the ratio of gearbox is high,it can try to help the motor stop on the downhill.But usually this
function only helps motor stop rolling back too fast.
Suggestion:factory default is Disable.
(28)Change Direction:
If the direction is not what you expected after finish the Identification angle operation,please just
choose Change Direction item.
Please click Write button to activate Change Direction function.The motor direction will be what
you expected after the power supply is reset.
Suggestion:factory default is Disable.
4.2 Step 2
(1)Motor Nominal Curr:When the controller is doing identification angle operation without load
on the motor shaft,there is a current requirement for identification operation.If the motor rated
power is very high,please increase this parameter to a higher value.Otherwise please keep it at
80 by default.If the motor power is very low such as hundreds of watts,please reduce this
parameter to lower value to match the low power motor for identification angle operation.
(2)Motor Poles: Motor Poles, The pair pole number*2. Range: 2~128
