Chapter 1 Introduction
1.1 Overview
This manual introduces the Kelly sinusoidal wave brushless BLDC motor
controllers‟ features, their installation and their maintenance. Read the manual carefully
and thoroughly before using the controller. If you have any questions, please contact the
support center of Kelly Controls.
Kelly‟s programmable motor controllers provide efficient, smooth and quiet controls
for electric motorcycles, golf carts and go-carts, as well as industrial motor control. It is mainly
supposed to solve noise problems of BLDC motor driving application. KLS controller can not
support sensorless brushess motor for now. Compared to the traditional trapezoidal waveform
control technology, this technique based on sinusoidal wave driving technology to reduce the
operation noise and 1/3 switching loss, which well meets the noise reduction and efficiency
requirements in the application of DC brushless motor. It uses high power MOSFET‟s and,
SVPWM and FOC to achieve efficiencies of up to 99% in most cases. A powerful
microprocessor brings in comprehensive and precise control to the controllers. It also allows
users to adjust parameters, conduct tests, and obtain diagnostic information quickly and easily.
People can program the KLS controller on PC software and Android App. There is one more
choice for customers to program KLS controller now. The APP software is based on Tablet with
Android OS. Customers may add a Z-TEK USB to RS232 cable for programming KLS controller
if they want to use Android Tablet.
Both PC software and Android APP can provide one screen to monitor the controller
parameters. Sometimes people can use a smallAndroid Tablet as display device.
KLS8080N/NPS is designed by opto-isolated technology. We specify 8-30V for
power supply which must be isolated from main battery pack B+/B-.You may use an
isolated DCDC converter or a separate 12V battery for power supply.KLS8080N is
supposed to work with BLDC motor with hall sensors.KLS8080NPS can work with
brushless motor with Sin/Cosin speed sensors.
KLS8080N/NPS controller included the fuse on the plastic case.
Anyway please try to do identification angle operation before running the motor.
And please don't try to connect the controller to user program while the motor is still running, let

Chapter 3 Wiring and Installation
3.1 Mounting the Controller
The controller can be oriented in any position which should be as clean and dry as possible,
and if necessary, shielded with a cover to protect it from water and contaminants.
To ensure full rated output power, the controller should be fastened to a clean, flat metal
surface with four screws. Applying silicon grease or some other thermal conductive material to
contact surface will enhance thermal performance.
Proper heat sinking and airflow are vital to achieve the full power capability of the controller.
The case outline and mounting holes‟ dimensions are shown in Figure 1.

•Make sure the wire is connected correctly
•Turn the PWR switch on.
•The fault code will be detected automatically at restart.
•With the brake switch open, select a direction and operate the throttle. The motor should
spin in the selected direction. Verify wiring or voltage and the fuse if it does not. The motor
should run faster with increasing throttle. If not, refer to the Table 1 code, and correct the
fault as determined by the fault code.
•Take the vehicle off the blocks and drive it in a clear area. It should have smooth
acceleration and good power.
Chapter 4 Programmable Parameters
KLS Configuration program allow users to set parameters according to the vehicle actual
working environment so as to be at its best.
The default parameters of the controller are not recommended for all applications. Make
sure set the proper parameters before making any test to avoid danger.
Customers can do program on PC software or Android App.The Android Tablet is
prefered.First of all,people need to do Identification angle function for KLS controller before
running the motor.The controller needs to be connected to batteries,motor and throttle before
Identification operation.That is to say,it is not enough to connect only power supply(PWR=pin7)

(3)Current Percent: Phase Current Percent. Range: 20~100
Functional description: The max motor current is (The Value * Peak Current of the Controller).
Suggestion: Factory default is 100%.
(4)Battery Limit: Battery Limit Current, Limit the max value of Battery Current. Range: 20~100
Functional description: Set max battery current so as to protect battery. A lower value means a
lower battery output current and better protective effect. But excessively low value will affect
acceleration.
Suggestion: Factory default is 100%.
(5)Identification Angle: Please download the instruction to how to use Identification angle
function from the website.
www.kellycontroller.com/support.php
If you can read 85 in Identification Angle item,that is to say,the system is stable and normal.

Kelly KLS8080N/NPS Sinusoidal Brushless Motor Controller User’s Manual V 1.10

Please fill in 170 for Identification Angle item in user program. Then please click Write button in
user program. Please wait a few seconds before restart the power supply. You will see some
info on Monitor screen after power supply is reset. If you see Reset error on the Monitor screen,
that is to say, the auto_Identification is finished. You can see 85 in the Identification Angle item
again. And the controller will blink error code. This is normal. Please reset the power supply
again. Then everything will be fine. The motor is ready to be drived by the KLS controller.
Range: 85 or 170, nothing else.
(6)TPS Low Err: Hall active pedal, if lower than the value, report the fault of TPS Type. Range:
0~20
(7)TPS High Err: Hall active pedal, if higher than the value, report the fault of TPS Type. Range:
80~100
As you may know,the output of hall throttle from Kelly is about from 0.86V to 4.2V.
Our controller will report 3.3 error code if the output of hall throttle is below 0.5V or above 4.5V
by default.
The controller will think the hall throttle is shorted or damaged if the output is beyond the range
from 0.5V to 4.5V.
You can adjust the threshold voltage below or above 0.5V.The controller will report the 3.3 code
to protect the system according to different types of hall throttle.
Because there are many different hall throttle suppliers in the world. The initial output can not be
always in the range of 0.5V to 4.5V.
But it doesn't make any differences if you choose 0-5V or 3-wire pot for the throttle type. That is
to say, these two settings are only useful for hall active throttle or pedal when you chose throtle
type at 2.
As the same goes, it is valid to adjust the high threshold voltage above 4.5V or below 4.5V.
Usually the hall output voltage is 4.2V Max. If you adjust it to lower value which is near 4.2V,it
may trigger the error code in normal way.
(8)TPS Type: TPS Type, 1:0-5V 3-wire 0-5K pot,5K is normal,2K-20K can be used;2:Hall active
throttle or pedal. Range: 1~2

speed.Range: 20~100 By default, it is set at 100%.Both F-N-R control and three speed function
used the same pin12.Needless to say, we can not use both functions at the same time. Three
Gears switch is supposed to enable F-N-R control. When this item is disabled, we can use three
speed function, vice versa.
Pin22 is low speed switch input port while Pin12 is high speed switch input port. When both
pin22 and pin12 are disconnected from pin11,the controller is driving with medium speed mode.
Three speed: This item is used to enable or disable three speed function. By default, it is at 0

Functional description: If enabled, the controller will detect the current pedal status when
release the brake. If throttle got effective output, the controller will report fault and not operate.
Suggestion: Set according to the practical situation, factory default is Disable.
(21)NTL H-Pedal: Neutral position High Pedal Disable. Only useful when Three gears switch
function is enabled.
If enable, the controller will detect the current pedal position or signal When the switch is in
neutral position.
If the throttle got effective output signal, the controller will not operate and report fault code.
Suggestion: Set according to the practical situation, factory default is Disable.
(22)Joystick function:
If enable, the controller can drive the motor on two directions without using any reversing
switch.
Just one single throttle can drive the motor on forward and reversing direction.
The stick shift throttle firmware can be called wig-wag or joystick operation. It is only a software
function. Usually It is useful for electric boat project. You still can use the common 0-5K pot or
0-5V throttle for the controller. If you don't choose the joystick, you operated the throttle in this
way. The motor speed will increase when the throttle is from 0V to 5V.
If you enable joystick for this controller in user program, you will start the motor from 2.5V
position.2.6V to 5V is forward.2.4V to 0V is backward.
2.4V to 2.6V is the throttle dead zone. Customers can adjust the throttle dead zone in user
program also.
Please note the common throttle will spring back to original position if you release the throttle.
Suggestion: factory default is Disable.
(23)Three Gears switch: It is used for function of F-N-R control.
Please check the wiring diagram in the manual for F-N-R control.
Suggestion: Set according to the practical situation, factory default is Disable.
(20-A)Three Gears Switch
Value range: Enable and Disable
Functional description: If enabled, the Forward switch will be activated. Please see figure 4.1.
Suggestion: Set according to the practical situation, factory default is Disable.
(20-B)Foot Switch
Value range: Enable and Disable
Functional description: If enabled, the foot switch will be activated. The controller will not accept
the throttle signal if the foot switch is turned off. Please see figure 4.1.

(24)Boost: If enabled, the controller will output max power for a while.
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
Suggestion: Set according to the real motor poles on the nameplate of the motor, factory default
is at 8.
(3)Speed Sensor Type: Speed Sensor Type, 2:Hal, 3:Resolver(Reservation), 4:Line Hall. Range:
2 or 4
Different sensors type. By defualt,it is set at 2
If you have a motor with 5V,Sin/Cosin, GND speed sensors, please choose it at 4.And please
inquire the KLS-8080NPS model before ordering.KLS-8080NPS can not support Resolver
sensor type for now.
(4)Resolver Poles: Resolver Poles, The pair pole number*2. Range: 2~32
It is only used for the Resolver sensor type which is not accepted by KLS-8080NPS controller
for now.
(5)Motor Temp Sensor: Motor Temp Sensor, 0：None,1:KTY84-130 or 150,2:KTY83-122.Range
0-2
High Temp Cut Out °C: Motor High Temp Cut Out, nominal value 130°C. Range: 60~170
Resume °C: Motor High Temp Resume Temp, nominal value 110°C. The controller will
resume work when the motor temp is at 110 degrees inside. Range: 60~170
(6)Line Hall Zero: It is only useful when the speed sensor is at 4.
Zero-Crossing point of Sine/Cosine linear hall sensors output signal. Usually the Sine/Cosine
speed sensor supplier provided sensors with 2.5V or 3.0V zero-crossing point.
You can change it back between 2.5V and 3.0V if the motor can not run.
