Product Details

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.

OFF

ON, Double pulse: PU is Clockwise pulse signal, DR is counterclockwise pulse signal

OFF, single pulse: PU is step pulse signal, DR is direction signal

Self detect switch (OFF: accept external signal, ON: send out 7.5KHz pulse by the driver，the microstep should be set more than 8)

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
PU-	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
DR-	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-	DC12-40V
AC、BC	Connect to the motor
+A、-A
+B、-B

! 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.
