Terminal definition description
Signal input terminal
⑴CP+: Pulse signal input positive terminal.
⑵CP-: Pulse signal input negative terminal.
⑶DIR+: Positive terminal for motor forward and reverse control.
⑷DIR-: The negative terminal for controlling the positive and negative rotation of the motor.
⑸EN+: Positive end of motor offline control.
⑹EN-: Motor offline control negative terminal.

Motor winding connections:
⑴A+: Connect the A+ phase of the motor winding.
⑵A-: Connect the motor winding A-phase.
⑶B+: Connect the B+ phase of the motor winding.
⑷B-: Connect the B- phase of the motor winding.

Connection for operating voltage:

⑵GND: negative DC power supply.

Optocoupler isolation connection method at signal input end
The input signal interface has two connection methods: users can use common anode connection or common cathode connection according to needs.
1. Common anode connection method: Connect CP+, DIR+, and EN+ to the power supply of the control system respectively. If the power supply is +5V, it can be connected directly. If the power supply is greater than +5V, an external current-limiting resistor R must be added. , ensuring a driving current of 8-15mA for the optical coupling inside the driver. The pulse input signal is connected through CP-; at this time, DIR- and EN- are active at low level.
2. Common cathode connection method: Connect CP-, DIR-, and EN- to the ground terminal of the control system (SGND, isolated from the power ground); the +5V pulse input signal is added through CP+; at this time, DIR+, EN+ Active high level. The connection value of the current limiting resistor R is the same as the common anode connection.

Note: The EN end does not need to be connected. When EN is valid, the motor rotor is in a free state (offline state). At this time, you can manually turn the motor shaft to make adjustments that suit you. After manual adjustment is completed, set EN to the invalid state to continue automatic control.
