Instructions for use of drive products：

Definition of large 4PIN green terminal of interface1

1. + (input positive voltage, Anode of switching power supply, If the voltage of the switching power supply is 24V, please adjust the switching power supply to the minimum);

2. LD+ (LD output positive);

3. LD- (LD output negative);

4. GND (input negative voltage, Cathode of switching power supply);

Definition of small 4PIN green terminal of interface 2

1. SIG- (input analog quantity -);

2. SIG+ (input analog quantity +);0~10V analog, corresponding current 0~3.3A

3. + (positive pole of input signal); This signal can make TTL signal, PWM signal, high level response greater than 3.3V

4. - (negative pole of input signal);

Definition of small 4PIN green terminal of interface 3:

1. GND (voltage feedback signal ground);

2. V (voltage feedback signal positive);

3. I (current feedback signal positive);

4. GND (current feedback signal ground);

Functional description:

1. The ± of interface 2 can be TTL modulation signal, DC voltage signal, sine wave signal, etc.;

2. The analog signal of interface 2 is 0-10V signal, corresponding to 0~100% current value

3. Test point: I+ is positive, connected to a multimeter 1.2V is 12A, which can accurately control the current of LD;

E. Debugging

1. W3 is the primary current limit; W4 is the secondary current limit; W2 adjusts the current; for example, 2A, the first step is to adjust W2 to the maximum, the second step is to adjust W4 to 2.05A, and the third step is to adjust W3 to 2A;
