Terminal number Signal type Signal description
SPEED output signal Speed signal output port, corresponding to the motor running speed, output corresponding pulse frequency
ALARM Alarm signal output port, normally 5V, 0V when fault occurs
SV control signal External speed control input port. When the external potentiometer adjusts speed, the middle lead wire is connected here, and the two sides are connected to VCC and COM ports
COM Public port (low level)
F / R Motor rotation direction control port, the F / R port is disconnected from the COM terminal to rotate the motor clockwise, short-circuit closed to rotate counterclockwise
EN Stop signal control terminal, the EN port and COM port are disconnected for the motor to stop slowly, and the short circuit is closed for normal operation.
BRK Motor fast brake signal port, disconnecting the BRK and COM terminals for fast braking and short-circuit closing for normal operation
