2.2.2、Sport mode flux weakening value：Flux weakening value for S gear: the parameter value is <3000, and
the vehicle speed is adjusted according to the motor parameters. BOOST weak magnetic value> high speed
weak magnetic value
2.2.3、Auto exit function: tick to jog key / uncheck to long press key, select one from two.
2.2.3.1、Check to make the jog effective. The weak magnetic time enters the exit and can be adjusted.
2.2：Downhill electric brake assist：start by select “HDC Enable”, downhill electric brake assist (slow down
in steep slopes) function. Enable electric brake by enter minimum speed, if less than the speed, the
function will be invalid.
2.2.1、Downhill brake assist function: the speed of entering downhill brake assist function is set according
to the actual road test speed standard according to the motor parameters.
2.2.2、Note: The drum motor is not suitable for use, resulting in loose motor shaft.
2.3 、Flux weakening compensation: only valid when the inner rotor motor type is selected as V-shaped
magnetic steel
Note: The maximum value of 255 is generally filled in 95
2.4、Three gear setting：Confirm the motor base speed value adjustment setting parameter value. The basic
speed is filled in according to the <Appendix EM_V3 Parameter Adjustment Calculation Formula>.
2.4.1、The low, medium, high, and third speed values are valid within 100% of the parameter value, and the
medium, high, and high speed values are exceeded and the 100% parameter value is filled. Exceeded by
weak magnetic file (medium, high, BOST)
2.4.2、In the flux weakening area, the actual parameters of the motor are adjusted, and the vehicle speed is
based on the road test.
2.4.3、Single voltage mode: The high voltage value is invalid.
2.4.4、Attention
2.4.4.1 、Drum motor: 60KM/H motor weak magnetic speed is less than <120%, 80KM/H motor weak
magnetic speed is less than <125%, 110KM/H motor weak magnetic speed is less than <135%.
2.4.4.2 Inner rotor motor Hall: The built-in Hall weak magnetic speed is less than <135%, and the external
Hall weak magnetic speed is less than 170%.
2.4.4.3、Internal rotor motor magnetic knitting: Built-in flux weakening speed <230%.
2.4.4.4The motor base speed exceeds 100% of the motor speed value and enters the weak value zone
adjustment parameter. BOOST>High speed weak magnetic file.
2.4.4.5 Weak magnetic failure: The flux weakening value exceeds the motor and controller parameter
values, causing the motor to demagnetize and the controller to burn MOS.
2.5、Jog/push selection: choose one
2.6、The three-speed default gear: the electric door lock opens the default several options.
2.7、Soft start setting: The smaller the value, the softer the start.
2.8、Speed limit setting:
2.8.1、Function selection: speed limit, unlimited speed, two choices, default speed limit
2.8.2 、The speed limit speed is calculated based on vehicle parameter requirements. <Appendix EM_V3
parameter adjustment calculation formula>
2.8.3 、The upper limit speed and the solution speed limit are determined according to customer
requirements.

2.8.4 、Speed relation of electric brake setting corresponding to weak magnetic acceleration: the speed
corresponding to the highest landing speed of the motor is set by the auxiliary enable of downhill electric
brake. When the setting value is lower than the rated speed of the motor, weak magnetic acceleration is
not required or optional. When the setting value is higher than the rated speed of the motor, weak
magnetic acceleration is required. Note: due to the loss of motor landing relative to no-load, the setting
value of downhill electric brake enabling is usually ≤(motor basic speed + maximum gear flux weakening
value) speed.
2.8.5 、Judge whether the maximum speed demagnetization value is reasonable. First, check the d-axis
current under the speed setting value of downhill electric brake enable. If the d-axis current value is
multiplied by 1.2 times, it is the setting value of the maximum demagnetization value (the second gear
demagnetization value on the setting page). For example, if the downhill point brake enable value is 800,
the motor turns to 800, and the d-axis current displays 500, then the maximum speed demagnetization
value is 500 ×1.2 = 600
