Stepper Motor Driver JB542M DC20-50V 4.0A 200Microstep
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 |
Microstep setting
The microsteps of the driver are set by SW5-SW8 terminal with the following 16 channels. The SW4 is for function setting.
Details are as below: Microsteps(pulse/R)
| Microstep | 200 | 400 | 800 | 1600 | 3200 | 6400 | 12800 | 25600 |

| SW7 | ON | ON | ON | ON | OFF | OFF | OFF | OFF |
| SW8 | OFF | OFF | OFF | OFF | OFF | OFF | OFF | OFF |
| SW4 | 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 | ||||||||
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+ | |

! 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
