    The MLA10641 high-performance microstepping driver has an output current capability from 2.0 Amps minimum to 
    10.0 Amps maximum (peak rating).  The MLA10641 driver operates with an AC voltage of 90-132 Volts.  The inputs 
    are optically isolated with a minimum sourcing of 7.0 mA per input (+5VDC minimum to +24VDC maximum).  The 
    clock  input  is  set  to  receive  either  positive  or  negative  edge  clocks  with  a  maximum  frequency  of  400KHz.    The 
    MLA10641  driver  offers  direction  control  and  motor  current  ON/OFF  capabilities.  The  Reduce  Current  Enabled 
    function automatically reduces motor current to 50% of set value after the last step is made. The driver has built-in 
    features to indicate power on (Green LED), clocks being received (Y ellow LED) and fault conditions (Red LED). 
    With the MLA10641, various step resolutions can be implemented by the onboard DIP switch.  These divisions range 
    from 200 steps per revolution to 12,800 steps per revolution.  Protection devices have been added to this driver for 
    phase-to-phase short-circuit, motor miswire, over-temperature and over-voltage conditions.

    Pin #Description
    1 Step Clock Input Anode (+): 
    A positive going edge on this isolated input advances the motor by one increment.  The size of 
    the increment is dependent on the Microstep Select Inputs of the DIP  switch.
    2 Step Clock Input Cathode (-)
    3 Direction Anode (+): This isolated input is used to change the direction of the motor.  Physical direction also depends on the 
    connection of the motor windings.
    4 Direction Cathode (-)
    5 ON/OFF Anode (+): This isolated input is used to enable and disable the output section of the driver.  When HIGH (open), the 
    outputs are enabled.  However, this input does not inhibit the step clock.
    6 ON/OFF Cathode (-)
    7 Fault Out (C): This is the collector of the optically isolated fault output.  When NO fault occurs, this output will conduct current 
    into the emitter.  Care must be taken to not pass more than 50mA of current through this transistor.
    8 Fault Out (E):  This is the emitter of optically isolated fault output.
    TB1: 8 Pin Terminal Block Description Pin Descriptions
    The Inputs on the MLA10641 are optically isolated with the anode (+) and cathode (-) both brought out to the user.  With no 
    current going through the opto-diode, the input is considered high.  To enable the input a minimum of 7.0 mA needs to be 
    sourced or sinked through the opto-diode.  This is done by simply placing a voltage ranging from +5 to +24VDC across the 
    two inputs of the opto-diode.  If sinking current, then all three anodes (+) should be tied together to the +voltage.  If sourcing 
    current  into  the  inputs,  all  three  cathodes  (-)  should  be  tied  together  and  grounded  as  shown  in  TYPICAL APPLICATION 
    HOOK-UP.  The MLA10641 also has an optically isolated Fault Output Signal.  This output has an open collector maximum 
    voltage of 30V and can sink up to 50mA.
    The Anodes (+) are pins 1, 3 and 5 and the Cathodes (-) are pins 2, 4 and 6.

    Reducing Output Current
    Reducing  the  output  current  is  accomplished  by  setting  switch  1  of  the  DIP  switch  to  the  ON  position.  This  should  occur 
    approximately 1 second after the last positive going edge of the step clock input.  The amount of current per phase in the 
    reduction mode is approximately 50% of the set current.The output current on the MLA10641 is set by an onboard potentiometer. This potentiometer determines the per phase peak 
    output current of the driver. The relationship between the output current and the potentiometer value is as follows:
    Peak Current
    Potentiometer Setting Peak CurrentPotentiometer Setting
    2.00A 0%6.00A 52%
    2.30A 10%6.80A 60%
    3.00A 20%7.50A 70%
    4.00A 30%8.40A** 80%
    4.80A 40%9.50A** 90%
    5.75A 50%10.00A** 100%
    Setting the Output Current:
    The specified motor current of 4.3A for the 34Y112S-LW8-MS (which is the bipolar value) is multiplied by a factor of 
    1.4 to determine the current adjustment potentiometer value of 6.0Amps o\
    r 52%. 
    WARNING: Do not set the current setting above the step motor’s rated current. When using a  higher current setting 
    into a motor, the motor will overheat and burn up. Should this occur, the driver will also be damaged.
    **Although the MLA10641 has an internal fan, current settings above 8.4Amps (80%) may require additional cooling.
    Phases 1 and 3 of the step motor are connected between pins 2 and 3 on the motor connector (TB3).  Phases 2 and 4 of 
    the step motor are connected between pins 4 and 5 on the motor connector (TB3).   The motors case should be grounded 
    to pin 1 on the motor connector (TB3) for protection.  Refer to  TYPICAL APPLICATION HOOK-UP.
    NOTE: The physical direction of the motor with respect to the direction input will depend on the connection of the motor 
    windings.  To reverse the direction of the motor with respect to the direction input, swap the wires on Phase 1 and Phase 3.  
    WARNING: Do not connect or disconnect motor wires while power is applied!
    Connecting the Stepper Motor: Power Supply Requirements
    The MLA10641 has an input line voltage ranging from 90-132VAC.  TB2 pin 1 is used as the hot terminal and is 
    internally fused, TB2 pin 2 is used as the neutral terminal and TB2 pin 3 is the EGND terminal. The EGND terminal 
    must be connected.

    Microstepping Selection (DIP Settings)
    Switches 2, 3, and 4 of the DIP switch select the microstep resolution of the driver. The table below shows thes standard 
    resolution values along with the associated positions for the select switches.   The standard waveforms are sinusoidal. The 
    steps/rev are based on a 200 step/rev motor.
