LC2086HA  2ph NEMA23 NEMA34 Stepper Motor Driver 24-80VDC 4.5A


Product  Overview

   LC2086HA is suitable for type 57-86 of two-phase hybrid stepper motor,

there are 14 kinds of micro step subdivisions ,max up to 256 segments;

The work scope of peak current is1.0 A - 4.5 A, 8 files of output current total,

the current resolution is 0.5 A; with torque settingsover-voltage and over-current protection functions. This work drive power supply is set to be direct current one, it is recommended that the operating voltage range is 24 v - 80 VDC.


It’s suitable for all kinds of automation equipment and instruments in the field of motion control ,such as: electronic processing and detection, semiconductor packaging, laser cutting and welding, laser typesetting, packing machines, engraving machine, marking machine, cutting machine, apparel plotter, NC machine tools, automated assembly equipment, etc. It’s the first choice for users that prefer low noise, high speed with superior  performance and with a stronger price competition.


Function Description of Drivers

drive function

operating instructions

Working current setting

The driver output current is set by three dip switches SW1 - SW3,

its output current has eight floors in all. About specific output current Settings, please refer to the drive panel.

Automatic half flow function

Users can set drive to automatic half flow function through SW4.

OFF shows the static current is set to be half of the dynamic current,

ON shows the static current is the same as dynamic current .

SW4 should be set to OFF in general use  in order to reduce the heating of the motor and driver , also to improve the reliability. The current will reduce to 50% automatically 0.4 seconds approximately after the pulse train stop (60% actual value), calorific value reduced by 36% in theory.



Micro step





The driver micro step subdivision is set by four dip switches SW5 -

SW8, there are 14 files of micro step subdivisions in all.

When users are setting segmentation, the driver should be stopped

first.  About the setting of micro step subdivision , please refer to the drive panel.




Drives have two red and green lights. One of the green light is power light, It will be abidingly on after the driver is electrified; the other red light is fault  indicating lamp, when being overvoltage and over current problems, trouble light will be abidingly on. After the fault being cleared, the red light turns off. When a driver becomes disabled, only re-up electricity and reuse can clear the fault.



PUL + and PUL - are the plus side and  minus side of  signal controlling.

DIR + and DIR - are the plus side and  minus side of direction signal.

ENA + and ENA -are the plus side and  minus side of enable signal.





A + and A - connectting the plus and minus side of step motor A phase  

winding.   B + B and B -connectting the plus and minus side of step motor B phase winding.   When A, B two phase winding exchanges, can make the motor to reverse direction.

Power port


Using the dc power to supply,  operating voltage range is suggested to be 24V-80VDC.




The  boundary  dimension of drive is : 117 * 78 * 34 mm,

The Installation pitch-row  is 111 mm.

 Either horizontal or vertical installation can work,

(vertical installation is recommended).

When installation, should make it close to the metal cabinet to facilitate heat dissipation.
