Driver terminals: A+, A-, B+, B-
4-wire motor: A+ (Red), A- (Green), B+ (Yellow), B- (Blue) (match with motor label)
6/8-wire motor: Series/parallel the same-phase windings (short-circuit same-phase terminals) first, then connect to A+/A-, B+/B-
PUL+ → PLC/Controller Pulse Output + (5-24V)
PUL- → Common GND
DIR+ → Direction Signal +
DIR- → Common GND
ENA+ (Optional) → Enable Signal + (enabled by default when floating)
ENA- → Common GND
Differential mode: Connect PUL+/PUL-, DIR+/DIR- to positive/negative terminals of differential signal
VCC → DC Power Supply Positive (12-32VDC)
GND → DC Power Supply Negative (common ground with control signal GND)
Current DIP switches (8/16-bit): Adjust in 0.1A steps up to 3.0A according to driver label
Microstepping DIP switches: Commonly used 16/32/64/128/256 microsteps, corresponding to 200/400/800/1600/3200/51200ppr
