NSPBLDS4810 brushless DC motor driver is the latest high-tech product of our company for medium-power
brushless motor. This product uses a large-scale integrated circuit to replace the original hardware design, with
higher anti-interference and fast response. This product is suitable for driving any three-phase brushless DC
motor, Hall or no Hall sensor, with peak current below 10A and power supply voltage between DC10V~50V. This
driver features low temperature operation at high current. The products are used in a series of electrical
automation control fields such as knitting equipment, medical equipment, food packaging machinery and electric
power tools.

Speed control
mode (VSP)
1. Connect with external potentiometer to adjust speed: connect the two fixed ends of the
external potentiometer (5K~10K) to the GND and +5V terminals of the driver respectively.
By connecting regulating terminal to the VSP terminal. The speed can be controlled by
external potentiometer, or inputting analog voltage to VSP terminal through other control
units (such as PLC, MCU, etc.). The voltage range of the VSP port is DC 0V~+ 5V,
corresponding to the speed of motor from 0 to max speed.
2. Input PWM signal to adjust speed: connect PWM signal positive terminal to VSP terminal
and negative terminal to GND. By setting the +5V PWM signal with the frequency of
10Hz-500Hz, through PWM duty cycle change to achieve speed adjustment.
Speed signal
output（FG）
The drive provides speed pulse signal of motor which is proportional to motor speed.
Speed calculation method: motor speed (RPM) = F÷N×60
F = Actual frequency measured on the FG pin with the frequency meter
N = motor poles pair (2 pairs pole motor N=2; 4 pairs pole motor N=4)
For example, if the user selects a 4pairs poles motor, when the output FG signal is 200 Hz,
motor speed = 200 ÷ 4 × 60 = 3000 rpm.
CW/ CCW rotati
on
（DIR）
By controlling the high and low level transitions of DIR terminal to control rotation of the
motor.
Note: In order to avoid huge impact to motor and mechanical equipment when motor
changes direction suddenly at high speed, the drive decelerate the motor until it stops when
DIR terminal receives commutation signal, then the motor changes direction and
accelerates to the set speed.
Start/stop
(EN）
By controlling the high and low level transitions of EN terminal to control RUN/STOP of the
motor. Motor runs normally when EN is in low level and stops when in high. When the
start/stop is used to control the motor to stop, the motor stops naturally. Its motion law is
related to load inertia. Factory setting is EN for allowed operation.

Safety Precautions
★Connecting motor and driver should be carried out under the condition of power failure
★Connect the power cable, motor winding wire and hall signal cable correctly according to the figure. Order of
the UVW phases must be consistent.
★Do not disassemble the driver without instruction to prevent device damage
★Do not touch all terminals during power-on operation
★Do not operate the drive without housing
★Impacting the drive may cause damage
Q&A
1. How to use the drive for the first time?
After properly connecting the power cable, motor cable and Hall wire, the external potentiometer slowly
accelerates. After the motor rotates correctly, it will test the functions such as enable and direction. If you are not
familiar with this product, please install it to the actual occasion after test in initial use.
2. What happens if the power supply is reversed?
The Driver will be broken.
3. What is the maximum voltage of the upper control signal?
The maximum voltage of the speed control signal is 5V. The drive will be broken with voltage above 5V.
4. Housing of the driver is heated after long period of work, is it normal?
It is normal. At normal temperature, the housing reaches 90 degrees after a long period of work, which will not
affect the performance.
5. The motor does not turn but shake when the power LED is on, what is the reason?
The phase wires and the hall wires may be connected incorrectly. Please test after wiring according to the motor
manual.
6. Can I adjust my motor speed to 6000 with this driver?
The maximum speed of the brushless motor is determined by the parameters of the motor itself. Driver can
control the motor speed from 0 to the max speed.
7. How can I connect this driver to my own motor?
Please make sure that the phase wires and Hall wires of the motor are defined before connecting. If you are not
sure, please consult the motor manufacturer. Improper connect will cause damage to the driver.
8. Is it possible to add more function to this driver or develop new product?
Yes, please feel free to contact us.
