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. Hall sensors cable can not be tied together with windings
cable.
3. Alarm conditions:
a. Hall sensor signals are not correct.
b. LV or OV for 2~3S.
c. Short circuit and Over temperature of case.
d. Over load for 6s continuously.
e. It can be reset by Turn-Off-On DC Power or Disable the driver
once.
4. LED indicator:
SC--------Bright=Short circuit , Dark=driver is OK
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/ (2x 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. Safe F/R:
If you change F/R of the driver rapidly, it will stop the power
stage and motor will be free until the speed is detected as
zero,and then to drive in correct direction. This means smooth
reverse.
7. Safe start:
If the motor speed is not detected as zero at power on, the
driver will be free until the motor speed is zero.
8. Driver setup by pot and switch: |
 |
 |
R-SV pot=SV voltage
ratio, R-LG pot=Loop gain, R-PC=Peak current ratio, R-RT
pot=Ramp time
SW1=60/120 Hall sensors, SW2=Open/Close loop,
SW3,4=Speed/Current loop, SW5=Loop filter time, SW6=SV ramp time
setting, SW7,8,9,10=Speed range setting.
9. 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) |
