Product Details

Stepper Motor Driver JB278M AC24-60V/DC24-80V 6.2A 200Microstep

Features

High performance, low price

16 channels constant angle and constant torque microstep, max revolution is up to 40,000 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 2.5A/phase to 6.2A/phase through 16 channels

Single power input, voltage range: AC24-60V (DC24-80V)

It can match 2 phase hybrid stepper motors whose current is under 6.2A, flange size ranges from 57mm to 86mm.

Wiring example

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

Terminal function

Mark	Function	Notes
PU+	Step pulse signal+	It can connect +5V or +24V, but an extra resistor is needed if it connect +24V
PU-	DP9=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-	DP9=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-	DP9=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-	DP9=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
AC	Power	AC24-60V(DC24-80)
AC	Power	AC24-60V(DC24-80)

! Caution

1. The input voltage can not exceed AC60V(DC80V) .

2. Input control signal is 5V, current-limiting resistance should be connected 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 80℃. Until the temperature falls to 50℃, 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
