CP-: Pulse signal input negative terminal. DIR+: Positive end of motor forward and reverse control. DIR-: The negative end of the motor's positive and negative control. Enable+: Positive end of motor offline control. Enable-: Motor off-line control negative terminal. Motor Winding Connection: A+: Connect the A+ phase of the motor winding. A-: Connect the A-phase of the motor winding. B+: Connect B+ phase of motor winding. B-: Connect B-phase of motor winding. Working voltage connection: Volt Current Condenser: DC power supply is positive (note: 10V VCC 42V). Ground: Negative DC power supply Signal Input: Optocoupler isolation connection Two Connection Methods for Input Signal Interface: The user can adopt the common anode connection method or the common cathode connection method as needed. 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 directly connected. If the power supply is higher than +5V, an external current limiting resistor R must be added. To keep that the drive current of 8-15mA is provided to the internal optical coupling of the driver. The pulse input signal is accessed through CP-; at this time, DIR- and Enable- are active at low level. 2. Common Cathode Connection: Connect CP-, DIR-, Enable- 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+, Enable+ are in Active high. The connection value of the current limiting resistor R is the same as the common anode connection method.
