Precise speed setting
Rotating setting knobSetting the required revolving speed
Slowly turn the knob rightwards to gradually increase the speed at 1r/min, and turn it
leftwards to gradually reduce the speed.
Set the speed data, press the knob to confirm,
restart the driver, the motor will run at the set speed.
Simple wiring
Connector connectionScrew free wiring
The connection of SD driver and motor
can be reached by connector.
Just click the orange button and insert
wires to finish wiring arrangement. No
need weld or professional tools.
Motor start/stop and direction
One click to start/stop the motorOne push-button to change the direction of the motor
Move the running switch rightwards to RUN,
then the motor starts rotating. Move the switch
leftwards to STAND-BY, the motor stops.
Control speed by"Direction toggle switch".
Direction can be shift when motor is  in a rotation status.
Five speed control modes
Rotate Speed Regulation knob to set the speedDigital setting to set the speed
Rotate the knob clockwise to accelerate,
anticlockwise to decelerate.
Set the speed data by knob, press SET to confirm,
restart the driver, the motor will run at the set speed.
PWM to set the speedPulse Frequency to set the speed
When speed setting mode is set as PWM,
the motor speed will vary via duty ratio(1%-99%). Refer to the following diagram.
When pulse frequency mode is confirmed, speed will vary via pulse frequency(100HZ~3KHZ).
Refer to the following diagram.
Abundant function modes settings
Analog setting of acceleration and deceleration time
On the back of the SD driver, there are
acceleration time knob(ACC) and deceleration
time knob(DEC). 0.2s(default value) to 15 sec
are available.
Acceleration and deceleration time
can be set by data mode.
Set the speed upper/lower limitBrake stop
Speed upper/lower limit can be set,
the default value is 0-4000r/min.
When FWD and REV is set as ON, the motor
stop rapidly, but the needed time depends on
the load inertia. The least time is 200ms.
Multistage speed data selectionDirection control by upper computer
Four periods(SPD1,SPD2,SPD3, SPD4) of
speed can be set. Speed can be switched
by MO and M1 terminal control.
When control mode is set as I/O port, motor
direction can be set by upper computer. When
REV or FWD is set as ON, motor direction shifts.
Signal and alarm output
Speed signal outputAlarm output
30 pulses output for 1r rotation. Speed output
signal can be detected by upper computer.
When motor is overload or locked,
alarm signal will detected by upper computer.
Parameter displayError display
Parameters such as Speed, Current,
Voltage and Temperature can be displayed.
When malfunction occurs, fault code
can be displayed on display panel or I/O port.
