5. Function and Usage

Choose any of the below speed command:
Build-in potentiometer: Speed reduced while CCW potentiometer, otherwise speed increased. Set the
potentiometer at minimum while use the external speed command.
External potentiometer: Connect on the GND and +5V of the drives, speed can be adjusted on external
potentiometer ((5K~100K) when connect SV terminal. Input simulate voltage through other control command (e.x. PLC,
SCM etc.) to SV terminal to achieve the speed adjust as well (relative GND). The range of the SV terminal is DC
0V~+5V, the relevant motor speed is 0~rated speed.
External digital signal speed regulation: Add 5V between SV and GND, speed can be adjusted by PWM control
between the 1KHz~2KHz, motor speed is influenced by duty. At this time, by adjusting the R-SV potentiometer, SV
digital signal amplitude can be 0~1.0 ratio attenuation processing. Generally, adjust R-SV to 1.0, SV input digital signal
without attenuation processing.
Motor running/stop control (EN)
Control the brushless motor to run or stop by controlling the terminal "EN" and "GND" connecting. The motor will
running when we connect the terminal "EN" to "GND"; if shut down, the motor will stop, and the stopping time will
decided by the motor inertia and load adding on the motor.
Motor rotation direction control (F/R)
Control the motor rotation direction by controlling the terminal "F/R" and "GND" connecting. When shut off terminal
"F/R" to terminal "GND", the motor will run at CW (view from motor output side), and when connect on, the motor will
run at another direction. For avoiding to damage the driver, please stop the motor running and then change the motor
rotation direction.
Brake the motor to stop (BK)
Motor stop can be controlled by connect BK and GND terminal. When shut off the BK and GND terminal, motor
running, otherwise motor will fast stop. Motor stopping time is decided by the motor inertia and load adding on the
