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. Over temperature for the control chip.
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:
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. 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) |
