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)
