Connection definitions:

Flag definitions
DC + / DC- DC power entry (DC12V ~ DC56V) positive and negative do not reversed
U, V, W motor leads (thick line connected U, V, W)
Hu, Hv, Hw Hall signal line (thin pick Hu, Hv, Hw)
REF + Hall positive power supply (power supply to the motor Hall + 5V)
REF- Hall negative power supply - (Hall ground connected to this port)
VCC power port external potentiometer (not to other external circuitry, can only do potentiometer power use)
SV external potentiometer terminals, External analog voltage input, PWM speed control signal input
COM Public port (0V reference level)
F / R directions: Leave or high forward and low reverse
EN Enable: High / Low stop / run
BRK fast brakes: High / Low stop / run
SPEED Corresponding to the running speed of the motor, the corresponding pulse frequency is output. Use SPEED-OUT to calculate the speed of the motor. The calculation formula is: N(RPM)=(F/P)*60/3
ALM Motor or drive control fault signal output is usually 5V, when a fault occurs, the level is 0V
