3.0A 2-phase stepper motor driver
Stepper motor driver,High performance, low price
[BRIEF INTRODUCTION] RB2403 is a constant torque driver with mircostep. Voltage range from DC12~40V,single power input. It can match 4 or 8 leads two phase hybrid step motors whose rated current under 3.0A,flange size range from 42~86mm.Own to unipolar constant current chopping circurt.The motor can run smoothly and hardly has any noise;Rising work voltage can greatly improve speed performance and output torque of motor.Once the pulse stops for 100ms, the phasecurrent will automatically cut by half,which can reduce chances of overheat.user can operate the driver with microstep inlow speed occasion.The upmost microstep can be set to 64X. |
[FEATURE]
* High proformance, low price
* Provide 8 kinds of microstep selection.
* Special control circuit greatly amounts to 200Kpps.
* Upmost response frequence amounts to 200Kpps.
* Once the pulse stops for 100ms,phase current automatically cut by half.
* Unipolar constant current chopper control.
* Photocoupler isolated input/output.
* Driver current from 0.3A/phase to 3.0A/phase.
* Single power input,voltage range from DC12-40V
* Overheat protection & overcurrent,under voltage protection.
* Dimension:112mm×74mm×34mm
* Net weight :276g
TERMINAL ASSIGNMENT
Mark | Function | Instruction |
Power | Poser indicator | When power on,the green led lights. |
Alert | Origin/Pulse output indicator | Passing the orgin or there is pulse output,the green LED lights |
+5V | Input signal position side | +5V is standard signal input voltage .but we can revise is according to clients' request. |
PU- | PU is 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 level:0~0.5V. High level:4~5V,pulse width≥2.5μs. |
DR- | DR is direction control signal | Use to change the direction.Input resistance is 220Ω, Requirement:input low:0~0.5V. Input high:4~5V,pulse width≥2.5μs |
MF- | Motor free signal | When effects,it cut off motor current,the driver stops working and sets the motor free. |
Im | Phase current setting adjuster | Turning it clockwise will increase the current from 0 to 3A.CCW decrease current. |
I double | Full/half current change | Idouble=on,the motor stops,the winding current is half rated current. |
M1/M2/M3 | Setting work microstep | According to RB2403 MICROSTEP SETTING LIST. |
