General Description
The MBC10SI1 is a low cost single axis step motor driver integrated with a programmable simple 
indexer.  The MBC10SI1 microstep driver/pulse generator has an output current capability of 1.5A 
minimum to 10.0A maximum (peak rating).  The MBC10SI1 driver operates with a DC voltage of 
20VDC to 80VDC.  The MBC10SI1’s internal controller has two different programmable motion 
profi les.  The MBC10SI1 also has directional soft and hard limit switch inputs, a busy output and 
a complete output letting the user know when an inded is fi nished.  The MBC10SI1 driver features 
direction control and motor current On/Off capabilities.  The “Reduce Current Enabled” feature 
automatically reduces motor current to 50% of the set value.  The driver has built in features to 
indicate power on (green LED), running (yellow LED) and error conditions (red LED).  The MBC-
10SI1 has a fi xed step resolution of 2000 steps/revolution for a 1.8° stepper motor.  The bipolar 
drive confi guration handles 4, 6, and 8 lead step motors and is also equipped with over current 
protection.  The MBC10SI1 communicates via USB communication.  The easy to use Windows 
software, SMPG-SMSI Software, is used to directly set up the two different motion profi les.

Motion Profi les and Running the Indexer
The programmable simple indexer has the ability to store up to two different motion profi les.  The 
profi les include a base speed (starting speed), a maximum speeds (running speed) acceleration/
deceleration, the number of steps (index) and a complete time (output signal).  The base speed 
has a range of 1-5000Hz, the maximum speed has a range of 1 Hz-50 kHz and the acceleration/
deceleration has a range of 100 to 9,999,999 steps/sec
2 and the index has a range of 0-8,388,607 
steps and the complete time has a range of 1-1000 milliseconds.
There are “two ways” to get the unit to index: Examples are shown on the next page.
1. The fi rst way is to directly control it from the computer with the software provided.  Once 
the motion profi les have been set, the unit is ready to run.  From the software, the user can 
select which profi le to run and then click the begin motion button.  If a soft limit command is 
sent or a soft limit input is activated, then the unit will immediately ramp down to base speed 
and stop.  To stop motion immediately a hard limit command needs to be sent or a hard limit 
input must be activated.
2.  The second way to make the unit run is to activate the individual index input.  When an 
index input is activated, it selects from memory the speed profi le that was selected.  If a soft 
limit input is activated, then the unit will immediately ramp down to base speed and continue 
running until the index has completed.  To stop all motion before the index has completed a 
hard limit input must be activated.

When powered and operated properly, the status LED will be green.  When a communication or 
program syntax error occurs, the LED will change to RED and an error code will be generated in the 
error code register.  To read and clear the error with the software, click on the “Verify Parameters” 
button.  To read and clear the error while in “Direct Mode” use the “!” command.  Once the error has 
been read and cleared, the LED will return to green and the error code register will be cleared.  Refer 
to the table in the trouble-shooting section for a list of the error codes.  When the indexer is running 
the yellow LED will be on.  Refer to the dimension drawing for location of the LEDs.  For more detail 
on “Direct Mode” Refer to the Direct Talk Mode Section of User’s Guide.
Baud Rates
A term used frequently in serial data communications.  A “baud” is defi ned as the reciprocal of the 
shortest pulse duration in a data word signal, including start, stop, and parity bits.  This is often taken 
to mean the same as “bits per second”, a term that expresses only the number of “data” bits per sec-
ond.  Very often, the parity bit is included as an information or data bit.  The MBC10SI1 only accepts 
a baud rate of 38400.
Inputs and Outputs
Inputs: All inputs are pulled up to 5VDC.  A logic “0” activates inputs that are pulled up.  An uncon-
nected input will always remain inactive.
Direction: When this input is not active, the motor will be moving in the clockwise or “+” direction.  
When this input is active, the motor will move in the counterclockwise or “-” direction.  This input is 
not read when a software index command is given.  To change direction while using the software, 
change the direction option there.  When two motors are used, the second motor will move in the 
opposite direction by default.
On/Off: When this input is not active, the motor will enabled or energized.  When this input is active, 
the motor will be disabled or de-energized.
Index 1 and 2: These inputs are used to select on of the two profi les.  When one of the profi les is acti-
vated, the unit will change the speeds, acceleration and index number based on the pre-programmed 
values for that profi le and begin the index.  Activate only one of these two inputs at once.
Soft Limits: These two inputs are controlled by the direction of the indexer.  When the indexer is 
running in the positive direction only soft+ will work.  When the indexer is running in the negative 
direction then only soft- will work.  When pulled low the motor will ramp down to base speed and 
continue running until the index is completed or a hard limit is reached.
Hard Limits: These two inputs are controlled by the direction of the indexer.  When the indexer is 
running in the positive direction only hard+ will work.  When the indexer is running in the negative 
direction then only hard- will work.  When pulled low the indexer will stop all pulses to the motor.  To 
reverse off of a Hard Limit, change directions, and activate another profi le input again to move in the 
opposite direction.
Complete Output: This is an open collector output that is capable of sinking 10mA.  It is current 
sinking when the indexer completes its motion and is only active for the pre-programmed time.
Busy Output: This is an open collector output that is capable of sinking 10mA.  It is current sinking 
when the indexer is running and open when the indexer is not running.

Setting the Output Current
The output current on the MBC10SI1 is set by the on-board potentiometer R29 (Refer to Dimen-
sions/Jumper and Potentiometer Locations).  This current adjust potentiometer determines the 
per phase peak output current of the driver.  This relationship between the output current and the 
potentiometer setting is as follows:
Potentiometer Settings
Reducing Output Current
Reducing the output current is accomplished automatically depending on the current reduction 
setting in the SMPG-SMSI software.  The amount of current per phase in the reduction mode is 
approximately 70% of the set current.  When the current reduction circuit is activated, the current 
reduction resistor is paralleled with the current adjustment potentiometer.  This lowers the total 
resistance value, and thus lowers the per phase output current.  This is done when the pulse 
generator is not running.

Determine Output Current
The output current used for motor when microstepping is determined differently from that of a 
full/half step unipolar driver.  In the MBC10SI1, a sine/cosine output function is used in rotating 
the motor.  The output current for a given motor is determined by the motors current rating and 
the wiring confi guration of the motor.  There is a current adjustment potentiometer used to set 
the output current of the MBC10SI1.  This sets the peak output current of the sine/cosine waves.  
The specifi ed motor current (which is the unipolar value) is multiplied by a factor of 1.0, 1.4, or 
2.0 depending on the motor confi guration (series, half-coil, or parallel).
Step Motor Confi gurations
Step motors can be confi gured as 4, 6, or 8 leads.  Each confi guration requires different currents.  
Refer to the lead confi gurations and the procedures to determine their output current.
WARNING! Step motors will run hot even when confi gured correctly.  Damage may occur to the 
motor if a higher than specifi ed current is used.  Most specifi ed motor currents are maximum 
values.  Care should be taken to not exceed these ratings.
6 Lead Motors
When confi guring a 6 lead motor in a half-coil confi guration (connected from one end of the coil 
to the center tap), multiply the specifi ed per phase (or unipolar) current rating by 1.4 to determine 
the current setting potentiometer value.  This confi guration will provide more torque at higher 
speeds when compared to the series confi guration.
When confi guring the motor in a series confi guration (connected from end to end with the cen-
ter tap fl oating) use the specifi ed per phase (or unipolar) current rating to determine the current 
setting potentiometer value.
4 Lead Motors
Multiply the specifi ed series motor current by 1.4 to determine the current adjustment potenti-
ometer value.  4 lead motors are usually rated with their appropriate series current, as opposed 
to the Phase Current, which is the rating for 6 and 8 lead motors. 
						

							August 2012 L01018510
8 Lead Motors
Series Connection: When confi guring the motor windings in series, use the per phase (or uni-
polar) current rating to determine the current setting potentiometer value.
Parallel Connection: When confi guring the motor windings in parallel, multiply the per phase (or 
unipolar) current rating by 2.0 to determine the current setting potentiometer value.
Note: After the current has been determined, according to the motor connections above, use 
the potentiometer setting table to choose the proper setting for the current setting potentiometer.
Connecting the Step Motor
The MBC10SI1 is designed to accept one motor.  For wiring of the motor refer to the pages con-
taining the connector descriptions and hookups diagrams.  The motor is wired into pins 3, 4, 5 
and 6 of the terminal block.
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 direc-
tion input, switch the wires on phase 1 and phase 3.  With the operation of 2 motors, they will run 
in the opposite direction when wired the same.
WARNING: Do not connect or disconnect motor wires while power is applied!
Circuit Protection
This driver is equipped with over current protection.
Note: When drive experiences a fault condition, it will seize to function.  Power down, inspect 
wiring, motors, etc. and allow for a 30 second pause to resume functioning.  If driver is too hot, 
additional ventilation and airfl ow should be added to prevent temperature to exceed recommended 
temperature limit.
