Specifications

Rated voltage

20-50VDC

Rated current

WS55-180S12A

WS55-220S14A

Note: Controller should be placed in a place with good ventilation and heat dissipation conditions.

Current limiting

WS55s-180About 13A

WS55s-220About 15A

Note: Current limiting is to avoid burning down motor and controller under heavy load. In actual use, do not try out and use over rated current.

Maximum supporting speed

The supporting speed is over 20000RPM, and the specific speed depends on the motor itself and the load.

Adjust speed

Two speed regulation modes:

1.External potentiometer: speed regulation through this potentiometer;

2.External Voltage: External Voltage10VDCVoltage speed regulation;

Note: Two kinds of speed regulation can not be used at the same time.

Speed output

PGSignal: There is a connection between the port and the ground.5VSpeed pulse output.

The output frequency is set toP(HzThe logarithm of motor level isNThe speed isF(RPMThen the output speed frequency is:P=F*N/60;

Alarm output

ALMSignal: There is an alarm pulse output between the port and the ground.

1.At normal operation, the port output5VHigh level;

2.When the motor is turned on, but the speed regulating signal is very low and the motor is not turning, the port signal is low. Namely: inENWhen the enable key is turned on, as long as the motor does not turn, the alarm port signal is low level, indicating that the current state is abnormal or in doubt, it should be handled.

ThreeIn the case of under-voltage, over-voltage, blocking, phase-gap and phase-short circuit, the port signal is low level.

Locked rotor protection

When the motor stops working, the power is restarted.

Power lamp

Green light: turn on when power is on

Status light

Red light:

When the power is turned on, the potentiometer or the external voltage is not turned on, and in the half standby state, the interval flickers once.

Enables not on, standby, spacing flicker seven times
