It's based on customer requirements to modify the software to adapt to changing market demands, this made for those interested in long-term
Show the customer is undoubtedly very important.
Description
1 self-learning function (LEARN)
Self-learning function automatically identifies motor 60 and 120 degrees, and very simple lines of the motor and controller for good.
Steps are as follows:
First self-learning lines (LEARN) ground, and then open the electric door lock, turn the motor a few steps, when the motor stops rotating, and failure means
Lamp (ErrLed) no flash nine under, that automatic identification has been successful. At this point turn to be able to turn the motor increases, the re-release the switch
Added switch to switch the direction of motor rotation can be. Identification is successful, the self-learning lines and broken ground, and then turn off the power door locks.
(Note: Since the motor is in the learning process should be carried out under no-load situation).
2 fixed phase function
Use a fixed phase function, you need to self-learning lines (LEARN) vacant, then the user need to match their own controller and motor
Hall lines and phase lines. Control panel of the MA, MB, MC, respectively, then the motor phase, SA, SB, SC Hall, then the motor line.
3 External lock motor function
External alarm controller, LKL take anti-theft alarm signal line, active low, the controller interface, next to the C-phase motor
W-hole side of the motor connected alarm test line, the controller VKEY (electric door lock wire) then the electric door lock alarm line, the controller
The BAT + anti-theft device is connected the power cord, BAT-connected alarm negative power cord.
When the external alarm signal is sent to the controller LKL low, the controller into the security state, and lock the motor.
4 external security of the motor winding direction recognition
Controller is powered on, turn the load increases to the maximum, the motor turning a few laps later, the motor winding direction to identify the good, and identify good
Data stored in the chip inside. This will not lead to another set with an external anti-theft motor direction. And ensure that no
Because the direction of the die set incorrectly which led to the lock motor problems.
5 soft-voltage and under voltage protection
When the battery voltage is less powerless to undervoltage protection, if it continues with the high current output, the battery internal resistance and line resistance will produce more
Large pressure drop, causing the controller immediately undervoltage protection. In view of this situation, our controller in the battery voltage less than 44V
When the limit value will decrease as the battery voltage decreases, the controller can continue to run a small current form, provides effective
The continued rise of the electric vehicle mileage. When the battery voltage is less than the undervoltage protection point, the shutdown output, protecting the battery.
6. The voice prompt feature
The control panel can be equipped with electric cars voice prompts, voice prompts can be a variety of failures, and running electric vehicles, such as:
"Cruise", "Motor fault", "turn to failure," "high speed" "Medium" "Low" and so on. Sound can be customized. Control
Board LED4 port access voice prompts.
7 Reverse function
When the reverse gear input (REV) input low level signal, the controller stops ahead and start testing the output speed of motor rotation,
When detected, the motor speed is reduced to low, and turn back to zero to re-coupled, the controller starts to control the motor reversal. Reverse
Maximum speed for the maximum forward speed of 30%.
8. Third gear function
SD is the third gear control panel input, output by the third gear buttons adjust the controller's maximum speed. A stall speed for maximum speed
65% of maximum speed in second gear speed of 78%, three are full.
In addition, third gear can do the hardware function, this time with SD port and LED3 mouth to select gear, when the SD port is low when
Third gear, when LED3 when a port is low profile, are high as the mid-range. Hardware stalls feature requires additional software.
9 ordinary brakes and electromagnetic brakes and brake anti-charging function
BKL is active low brake input, BKH is a high effective braking input, EBK is selected electromagnetic brake mouth, EBK access
To select the electromagnetic brake, otherwise ordinary brakes. EBK next to a ground. Electromagnetic brake with anti-charge effect, while
Counter-charging pressure limiting function.
10 manual and automatic cruise function
When testing the cruise control on the power input (DS), if it is low, then enter the auto-cruise state, if it is high,
Cruise state is entered manually. DS next to a ground point, the user can short-circuit to the ground state is set to automatic cruise
State.
11 power functions
Controller detects the signal input power (ZL) of pulses, according to the pulse frequency (ie, foot speed) to control
Motor output ratio. Effective power pulse duty cycle must be greater than 60%.
12 speed and speed limit function
XS and TS are the speed limits and speed input. Effective speed control switch to the voltage :1.35 - 3 .2 V, when the voltage is lower than 1.35V, the
Speed is zero, when the voltage is above 3.2V when full. Full speed when the speed is the speed limit to 67%.
