Application notes:
The 5V output port on the driver board prohibits connect external
device. It is only applicable to the external potentiometer and
switch of the board for speed regulation and reversal.
The “M” terminal on the JYQD_V8.3E driver board is the motor speed
pulse output signal (push-pull output), and the maximum output
current is less than 5mA.
Wiring Diagram:
5V -----Driver board internal output voltage
M ---- Motor speed pulse signal output port, 5V pulse signal.
1. Control port
Z/F---- Rotating direction control ports. Connect “5V” high level
or no connect is Forward direction, connect 0 V low level or
connect to GND is reverse direction.
VR ----Speed control port. Analog voltage linear speed regulation
0.1v -5V, The input resistance is 20K Ohm ,connect with GND when
input PWM speed regulation, PWM frequency:1-20KHZ; Duty cycle
0-100%
GND—Used for Drive board internal control
2. Power port
MA ----motor phase A
MB ---- motor phase B
MC---- motor phase C
GND----DC-
VCC----DC +
3. Use shielded wires if the drivers board has more than 50 cm
distance from the motor, otherwise it may lead to abnormal driving,
affecting the normal use.
4.Control port distance: 2.54mm,Power port distance:3.96 mm
5. Pay attention to the insulation between the driver MOSFET and
the heatsink or the installation plate.
Dimensional Drawing:
We can supply extra assy as connector wires and heatsink.
