Wiring diagram:
| Signal | Terminal | Content |
Output
signal | ALM | The motor or driver controls the fault signal output signal, which is normally 5V,
and the level is 0V when the fault occurs. |
| | SPEED | Corresponding to the operating speed of the motor, the corresponding pulse frequency is output. With SPEED-OUT, the speed of the motor can be calculated.
The calculation formula is:
N(rpm)=(F/P)*60/3
F:Output pulse frequency(HZ);P:Motor grade logarithm；N:Motor speed
For example: motor 4 pole
F=1sec/2ms=500Hz
N(rpm)=(500/4)*60/3=2500 |
Control
signal | BRK | When the BRK and COM terminals are disconnected or the high level is input,
the motor brake stops. When the motor is shorted or low level, the motor runs. |
| | EN | When the EN terminal is disconnected from the COM terminal
or the high-level input is input, the motor stops slowly. When the short-circuit
or low-level input is used, the motor runs. |
| | F/R | When the F/R terminal is short-circuited with the COM terminal or
the high-level input,the motor rotates forward, and when the short-circuit or
low-level input is used, the motor reverses. |
| | COM | Public port (OV reference level) |
| | SV | ①external speed potentiometer ②external analog signal input ③ pulse frequency input |
| | VCC | External potentiometer interface |
| Hall signal | REF+ | DC brushless motor Hall signal power supply. |
| | HU | DC brushless motor Hall signal HU. |
| | HV | DC brushless motor Hall signal HV. |
| | HW | DC brushless motor Hall signal HW. |
| | REF- | The DC brushless motor Hall signal is grounded. |
Motor
connection | U | DC brushless motor U phase. |
| | V | DC brushless motor V phase. |
| | W | DC brushless motor W phase. |
Power
connection | DC- | DC power input to the negative pole. |
| | DC+ | The DC power input is positive. (Voltage range DC24V-DC52V) |
