Output    current setting

  Users can set the driver Microstep by the    SW1-SW5 five switches. The setting of the specific Microstep subdivision,    please refer to the instructions of the driver panel figure..

Double    pulse setting

    SW7 sets pulse mode, setting &ldquo;on''    as double pulse mode, setting &ldquo;off'' as pulse + direction mode.,CW+/CW is Clockwise ,CCW+/CCW-  is Counterclockwise , need to confirm the    wire of stepper motor ?

Automatic    half current function

    Users can set the driver half flow    function by SW6. "OFF" indicates the quiescent current is set to    half of the dynamic current, that is to say, 0.5 seconds after the cessation    of the pulse, current reduce to about half automatically. "ON"    indicates the quiescent current and the dynamic current are the same. User    can set SW6 to "OFF", in order to reduce motor and driver heating    and improve reliability.

Self    test function

   When SW1-SW5 is OFF , Inner of drive send 1K    pulse to test whether the motor,wire,and self is normal?

signal    Interface

  PUL+ and PUL- are the positive and negative    side of control pulse signal; DIR+ and DIR- are the positive and negative    side of direction signal; ENA+ and ENA- are the positive and negative side of    enable signal .

Motor    Interface

   A+ and A- are connected to a phase winding    of motor; B+ and B- are connected to another phase winding of motor. If you    need to backward, one of the phase windings can be reversed .

Power    Interface

    It uses DC power supply,recommended working voltage is 10-36VDC,power is over 50W,voltage shouldn&rsquo;t    be over 36VDC and  below 10VDC?

Indicator    Lightor

  There are two indicator lights. Power    indicator is green. When the driver power on, the green light will always be    lit. Fault indicator is red, when there is over-voltage or over-current    fault, the red light will always be lit; after the driver fault is cleared,    if re-power the red light will be off.?

Installation

  The size of motor driver is 86×55×20 mm,mounting holes is 78mm?Chest and upright installation are ok,we suggest upright installation? During installation, it should be close to the metal    cabinet for heat dissipation.
