Weight: about 201g Wiring terminal definition description: -Signal input terminal: 1. CP+: pulse signal input positive terminal 2. CP-: pulse signal input negative terminal 3. DIR+: motor forward and reverse control positive terminal 4. DIR-: motor forward and reverse control negative terminal 5. EN+: motor offline control positive terminal 6. EN-: motor offline control negative terminal -Motor winding connection: 1. A+: connect motor winding A+ phase 2. A-: connect to motor winding phase A- 3. B+: connect motor winding B+ phase 4. B-: connect motor winding B- phase -Connections for operating voltage: 1. VCC: DC power supply positive ( note: 10V ＜VCC ＜42V) 2. GND: DC power supply negative -Input signal interface has two connection methods: users can use the common anode connection method or common cathode connection method according to the need 1. Common anode connection: connect CP+, DIR+ and EN+ to the power supply of the control system, if the power supply is +5V, then it can be connected directly, if the power supply is greater than +5V, then it is necessary to add another external current limiting resistor R, to ensure that the internal optical coupler of the driver can provide a driving current of 8-15mA. pulse input signal through the CP-access; at this time, DIR-, EN- in the low level
