WS55-180 controller description:
I. controller overview
The controller is applicable to the control of DC three-phase brushless DC motor
Stream 10A, with
1. start stop;
2. external potentiometer analog speed regulation;
3. inertia stops;
4. positive inversion;
5. undervoltage and overvoltage protection;
6. block protection;
7. compatible with Holzer and no Holzer: switch off power when switching between each other;
Two controller performance parameters
Function item
Specifications
Voltage range: 20-50VDC
Rated current: 8A
Rated output power:Confirm according to actual product,
Current limit: About 10A
Position sensing mode
Support Holzer and no Holzer position sensing, Holzer electric angle is 120degrees
Maximum support speed The speed depends on the motor itself and the load insulation resistance>100MΩ at ambient temperature and atmospheric pressure

Positive inversion
F/R: turn back when you're low
Four 、 protection function and explanation
V undervoltage overvoltage protection: when the working voltage drops to a certain value, the system starts under voltage protection, that is, the motor inertia stops; when the working voltage rises to a certain value, the system starts over-voltage protection;
V over-current protection: when the current is over, the system starts over-current protection, in order to prevent damage to the controller or motor, the motor inertia stops, the current is normal, the motor automatically back to normal work;
V blocking protection: Motor blockage after maintaining the maximum current of hundreds of milliseconds, close the output control, motor inertia stop rotating; within the prescribed time, if the lifting of the stall after the hand is to restore the normal operation;
Five, the use of environment and parameters
Function item
Specifications
Storage temperature: -20℃～ +65℃
Using environment:
Avoid direct contact with dust, fumes and corrosive gases
Temperature: 0-45 DEG C
Humidity: < 80%, no frost, frost free
Shock: 5.9m/S2MAX
Storage humidity: 0~95%RH
Six. Failure phenomena and analysis
Fault phenomenon
Failure cause analysis
The motor does not rotate
1. check the power supply is normal;
2. check the wiring is reliable and correct;
3. Holzer's positive and negative error. The mistake is liable to cause Holzer to damage;
4. Holzer line and motor line position combination error
The motor is very slow, fast, or dithered
1. check the voltage is normal
2. check Holzer's phase is correct, Holzer phase easily wrong, check carefully
