Stepper Motor Driver JB430M DC12-40V 0-3.0A 6400 pulse/R
Features
6 channels constant angle and constant torque microstep, highest microstep is up to 6400 pulse/R
Upmost response frequency amounts to 150Kpps
Once the pulse stops over 100ms, the phase current will automatically cut by half
Bipolar constant current chopper control
Opto-isolated signal Input/Output
Driving current is continuously adjustable from 0A/phase to 3A/phase
Single power input, voltage range: DC12-40V
It can match 2 phase hybrid stepper motors whose current is under 3A, flange size ranges from 28mm to 57mm.
Wiring and Dimension example


Current setting
  
Microstep setting

| Microstep | 200 | 400 | 800 | 1600 | 3200 | 6400 | 
| SW1 | OFF | OFF | OFF | ON | ON | ON | 
| SW2 | OFF | ON | ON | OFF | ON | ON | 
| SW3 | ON | OFF | ON | ON | OFF | ON | 
| SW5 | OFF: accept external pulse signal ON: Adjust Speed RP, the internal pulse is 0-10KHz/s | |||||
Terminal function
| Mark | Function | Notes | 
| Power | Power indicator | The green indicator lights when the power is on. | 
| RV | Pulse speed potentiometer | Adjust the internal pulse frequency of the driver. When the SW5 is ON, it will decrease counterclockwise and increase clockwise. Range: 0-10KHz/s | 
| Im | Current setting potentiometer | Adjust motor’s phase current, it will decrease counterclockwise and increase clockwise. | 
| PU- | Step pulse signal- | Effects on falling edge, the motor goes one step as the pulse input change from “high” to “low”. Input resistance is 220Ω. Requirement: low voltage:0-0.5V, high voltage:4-5V, pulse width >2.5μs | 
| PU+ | Step pulse signal+ | It can connect +5V - +24V, but an extra resistor is needed when it is over +5V | 
| MF- | Motor Free signal- | Once effects, it will cut off the motor current, the driver stops working and sets the motor free | 
| MF+ | Motor Free signal+ | It can connect +5V - +24V, but an extra resistor is needed when it is over +5V | 
| DR- | Direction control signal- | Change motor’s direction of rotation. Input resistance is 220Ω. Requirement: low voltage:0-0.5V | 
| DR+ | Direction control signal+ | It can connect +5V - +24V, but an extra resistor is needed when it is over +5V | 
| V- | Power- | DC12-40V | 
| V+ | Power+ | |
| B- | Connect to the motor |

! Caution
1. Do not reverse the power input, input voltage should not exceed DC40V.
2. Input control signal is 5V, current-limiting resistor should be connected when it is over 5V.
