Stepper Motor Driver JB244M DC12-40V 4.0A 200Microstep
Features
High performance, low price
16 channels constant angle and constant torque microstep, highest microstep is up to 200
An unique control circuit is adopted
Upmost response frequency amounts to 200Kpps
Once the pulse stops over 100ms, the phase current will automatically cut by half
Bipolar constant current chopper control
Driving current is continuously adjustable from 0.5A/phase to 4A/phase
Single power input, voltage range: DC12-40V
It can match 2 phase 6 leads or 8 leads hybrid stepper motors whose current is under 4A, flange size ranges from 42mm to 57mm.

Terminal function
Mark | Function | Notes |
O.H | Alarm indicator | The red indicator lights when overheat occurs. |
TM | Power indicator | The green indicator lights when signal TM is effective. |
Im | Current setting adjuster | Adjust motor’s phase current. Turning it clockwise will increase the current output, counterclockwise will decrease |
PU+ | Step pulse signal+ | It can connect +5V or +24V, but an extra resistor is needed if it connect +24V |
PU- | D2=OFF, 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 voltage:0-0.5V, high voltage:4-5V, pulse width >2.5μs |
D2=ON, PU is clockwise pulse signal | ||
DR+ | Direction control signal+ | It can connect +5V or +24V, but an extra resistor is needed if it connect +24V |
DR- | D2=OFF, DR is direction control signal | Change motor’s direction of rotation. Input resistance is 220Ω. Requirement: low voltage:0-0.5V, high voltage:4-5V, pulse width >2.5μs |
D2=ON, DR is counterclockwise pulse signal | ||
MF+ | Motor Free signal+ | It can connect +5V or +24V, but an extra resistor is needed if it connect +24V |
MF- | Motor Free signal- | Once effects, it will cut off the motor current, the driver stops working and sets the motor free |
FL+ | Overheat protection signal+ | It can connect +5V or +24V, but an extra resistor is needed if it connect +24V |
FL- | Overheat protection signal- | The motor current is cut off automatically and signal FL is effective (low voltage) when temperature of the driver is over 70℃. The driver will restart working and clear the FL signal when the temperature falls to 50℃。 |
V+ | Power+ | DC12-40V |
V- | Power- | |
AC、BC | 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 resistance should be connected when it is over 5V.
3. Alarm indicator O.H lights and the driver stops working when the driver temperature is over 70℃. It will restart to work automatically until the temperature falls to 50℃. The heat sink is needed when overheat occurs
4. 6 or 8 leads motors have to be used due to the special control circuit in the driver.
