110V/220V AC input BLDC motor driver with hall sequence
self-adapting, PWM & analog voltage speed control.
Safety Warning:
Installed on a non-flammable metal frame to prevent the
instruation of dust, corrosive gases, conductive objects, liquids
and flammable materials, and maintain good heat dissipation
conditions;
Protects the drive from shocks;
Do not connect the power input cable to the output U, V, and W
terminals;
Please confirm whether the input power supply voltage of the main
circuit is within the allowable operating voltage range of the
driver;
Do not arbitrarily test the high voltage resistance and
insulation performance of the driver;
According to the illustrated method, correctly connect the power
wires, motor phase wires, Hall signal wires and control signal
wires, and note that the sequence of UVW must be consistent;
Please have a professional electrical engineer carry out the
wiring operation;
Before wiring, please confirm that the input power supply is in
the state of being cut off, and the wiring and inspection must be
carried out after the power supply is cut off and the driver LED
indicator is off;
When plugging and unplugging the terminal blocks of the driver,
make sure that the driver indicator light is off before proceeding;
It is strictly forbidden to touch all terminals during power-on
operation;
If the Hall phase sequence is incorrect or the Hall phase
sequence self-learning is not carried out, the motor cannot run
normally, and if the VSP/PWM input instruction is too large, the
driver will be damaged.
It is not allowed to remove the circuit board and heat sink
connections or modify them;
The driver signal ground (common ground) is not zero potential,
and it needs to be isolated when connected to any other facility,
unless the connected facility ground is floating grounded,
otherwise it will cause a short circuit and damage the equipment;
Note: This error may cause damage to the device!
Danger: Indicates that the operation error will cause damage to
the device and may endanger personal safety!

Feature description
Select the speed regulation mode(VSP)
1.It can be connected to analog voltage or PWM signal
2. Analog voltage input, inout range 0-5V, 0.5-4.5V indicates 0-max
speed, when it is lower than 0.5v, the speed is 0, and when it is
higher than 4.5V, the speed is the maximum it can be connected to
the potentiometer for speed regulation, it is recommended to use
5-10K resistance, and the two ends of the potentiometer are
connected to +5V and GND terminals respectively. The potentiometer
is terminated with a VSP in the middle,
3. PWM signal input, enter a range 0%-100%, 10%-90% means 0-Max
speed. Below 10%, the speed is 0, Higher than 90%, the speed is
maximum. PWM the recommended frequency of the signal 500Hz-10KHz,
too high will result in reduced accuracy, and too low will result
in counter overflow errors.
Speed signal output(FG)
The drive provides a motor tachometer pulse signal, which is
proportional to the motor speed.
Rotational speed calculation: motor speed (RPM) = 20×F÷N
F = The frequency on the FG terminal is actually measured with a
frequency meter, in Hz
N = number of pole pairs of the motor (2 pole motors N = 2, 4 pole
motors N = 4, and so on)
For example, if the user chooses a 2-pole motor, then: when the
measured
FG signal is 500Hz, the motor speed = 20×500÷2=5000 rpm.
Motor forward/reverse rotation(F/R)
By controlling the conversion of the F/R high (or not) and low
level of the terminal, the forward and reverse rotation of the
motor can be controlled.
Note: In order to avoid huge impact on the motor and mechanical
equipment, before changing the F/T signal, be sure to reduce the
motor to a
certain speed (according to the actual working conditions) or even
stop the machine to avoid damage to the equipment.
Start/stop signal(S/T)
By controlling the conversion of the S/T high (or not) and low
level of the terminal, the motor can be started/stopped. When the
S/T is low, the motor runs, and when the S/T is high (or not), the
motor stops.
