    Technical Note:

    1.Control signals:
    F/R-----H or Open=Forward, L or Close=Reverse
    EN------H or Open=Disable, L or Close=Enable
    BK------H or Open=Running, L or Close=Brake
    SV------0~5V speed reference(112K input resistance)
    PG-----Speed pulse output(OC)
    ALM---Alarm output(OC)

    2. Signal wire:
    Control Signal cable and hall sensors cable can not be tied together with windings cable, otherwise, it will take interference. The long wire should be shielded wire.

    3. Alarm conditions:
    a. Hall sensor signals are not correct.
    b. LV or OV for 1~3S.
    c. Over temperature of case (80℃).
    d. Over load for 5~6s continuously.
    e. It can be reset by Turn-Off-On DC Power or Disable the driver once.

    4. LED indicator:
    P/A-------Bright=Driver is OK, Blink=Driver is in alarm
    SHAFT----Bright=Motor shaft is moving, Dark=Motor shaft is in static

    5. Braking operation:
    The motor speed must be less than the safe brake speed Ns when you brake the motor.
    For Y windings, Ns=√3 x Ip x RL x N/ (2 x Vp)
    For △windings, Ns=IP x RL x N/ (2 x √3 x Vp) 
    Ip=Peak current(A), RL=Line to line resistance of windings(Ohm)
    N=No-load speed(rpm), Vp=Rated voltage(V), Ns=Safe brake speed(rpm)

    6. Driver setup by pot and switch:
    R-SV pot=SV voltage ratio,  R-PC=Peak current ratio, SW1=Open/Close loop, SW2=Loop filter time, SW3=Loop gain, SW4,5,6=Speed range setting, SW7,8=SV ramp time setting

    7. Peak current selection:
    Ip>=2xIr or Ip>=4xPo/Vp, Ip is peak current of driver(A), Ir is rated current of motor(A), Po is rated output power of motor(W), Vp is rated voltage of driver(V)
