Frequency-torque characteristics

Wiring Diagram

Installation precaution

1. Data of electrical characteristics and technical data are both measured by JB542M driver, testing voltage DC28V.
2. When motor mounted, be sure its front cover should be installed to the seam allowance position and attention to the fit tolerance and strictly ensure that the concentricity of electrical motor axis with the load.
3. Please do not connect wrong phase when fitting the motor and driver.

2 Stepper motor driver

Stepper motor driver JB542M 4.0A DC20-50V 200Microsteps

Features

High performance, low price

16 channels constant angle and constant torque microstep, max revolution is up to 40000 pulse/R

Upmost response frequency amounts to 200Kpps

Once the pulse stops over 1.5s, the phase current will be automatically reduced to half of pre-set current

Opto-isolated signal Input/Output

Driving current can be adjusted from 1.0A/phase to 4.0A/phase through 8 channels

Single power input, voltage range: DC20-50V

It can match 2 phase hybrid stepper motors whose current is under 6.0A, flange size ranges from 42mm to 86mm.

Wiring and Dimension example

Current setting

The working current of the driver is set by SW1-SW3 terminal, for more details please refer to the diagram below .

Current (A)	1.0	1.2	1.5	2.0	2.5	3.0	3.5	4.0
SW1	ON	OFF	ON	OFF	ON	OFF	ON	OFF
SW2	ON	ON	OFF	OFF	ON	ON	OFF	OFF
SW3	ON	ON	ON	ON	OFF	OFF	OFF	OFF

The SW4 is used to set Half current/Full current: OFF=Half Current ON=Full current

Microstep setting

The microsteps of the driver are set by SW5-SW8 terminal with the following 16 channels. Details are as below: Microsteps(pulse/R)

Microstep	200	400	800	1600	3200	6400	12800	25600
SW5	ON	OFF	ON	OFF	ON	OFF	ON	OFF
SW6	ON	ON	OFF	OFF	ON	ON	OFF	OFF
SW7	ON	ON	ON	ON	OFF	OFF	OFF	OFF
SW8	ON	ON	ON	ON	ON	ON	ON	ON
Microstep	1000	2000	4000	5000	8000	10000	20000	40000
SW5	ON	OFF	ON	OFF	ON	OFF	ON	OFF
SW6	ON	ON	OFF	OFF	ON	ON	OFF	OFF
SW7	ON	ON	ON	ON	OFF	OFF	OFF	OFF
SW8	OFF	OFF	OFF	OFF	OFF	OFF	OFF	OFF

Note: The microsteps can be customized according to clients’ requirement.

Terminal function

Mark	Function	Notes
PU+	Step pulse signal+	It can connect +5V or +28V, and an extra resistor is not needed if it connect +28V
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
DR+	Direction control signal+	It can connect +5V or +28V, and an extra resistor is not needed if it connect +28V
DR-	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
MF+	Motor Free signal+	It can connect +5V or +28V, and an extra resistor is not needed if it connect +28V
MF-	Motor Free signal-	Once effects, it will cut off the motor current, the driver stops working and sets the motor free
V-	Power-	DC20-50V
V+	Power+
A+	Connect to the motor
A-
B+
B-

! Caution

1.The input voltage can not exceed DC50V .

2.Input control signal ranges from +5V to +28V, current-limiting resistance is not needed when it is over +5V.

3.The input pulse signal effects on falling edge

4.ALM lights and the driver stops working when the driver temperature is over 80C. Until the temperature falls to 50C, it will restart to work after powered-up. The heat sink is needed when overheat occurs

5.ALM lights if it is short circuit, please check motor leads and eliminate other short faults, and then repower up to restore

6.ALM lights if the motor does not connect well with the driver, please check motor leads and repower up to restore
