驱动器连接 Drive connection




Name BM82H two-phase stepper motor driver
VCC (+ 5V)

Pulse signal: Pulse control signal. At this time, the rising edge of the pulse is valid. PUL- 4-5V at high level and 0-0.5V at low level. For reliable response, the pulse width is greater than 1.5μs.

If + 12V or 24V is used, a series resistor (1K or 2K) is required to limit the current.

PUL- (PUL)
VCC (+ 5V)

Direction signal: high / low level signal, corresponding to the forward and reverse of the motor. In order to ensure the reliable response of the motor, the direction signal should be established at least 1.5 μs before the pulse signal.

The initial running direction of the motor is related to the wiring of the motor. Interchanging any phase winding (such as A +, A-) can change the initial running direction of the motor.

DIR- (DIR)
VCC + (+ 5V)
Enable signal: This input signal is used to enable / disable, enable at high level, the driver cannot work at low level. Under normal circumstances, it can be left unconnected, and it is automatically enabled when it is left floating.
ENA- (ENA)
GND DC power input negative
+ V DC power input, any between 12VDC ~ 36VDC, but the recommended value is about 24VDC
A Motor A phase. A +, A- intermodulation, can change the motor running direction
B Motor B phase. B +, B- intermodulation, can change the motor running direction
电流设定 Current setting




SW1-SW3三位拨码开关用于设置电机运行工作电流(动态电流),SW4拨码开关用于设置电机静止时的电流(静态电流或保持电流)。 SW1-SW3 three-position DIP switch is used to set the operating current (dynamic current) of the motor, and SW4 DIP switch is used to set the current (static current or holding current) when the motor is stationary. A total of 8 current levels can be set with the 3-position DIP switch.

全流/半流锁定 Full-flow / half-flow lock
The quiescent current can be set with the SW4 switch. OFF means that the quiescent current is set to about half of the dynamic current (actually 60%). ON means that the quiescent current is the same as the dynamic current. In general, SW4 should be set to OFF, so as to reduce the heating of the motor and stepper motor driver and improve the service life. About 0.2 seconds after the pulse stops, the current will be automatically reduced to 60% of the set value, and the calorific value is theoretically reduced to 36% (heat generation is proportional to the square of the current).
