Introduction
The MBC25P11 is an economical single axis step motor driver integrated with a programmable pulse
generator. The MBC25P11 microstep driver/pulse generator has an output current capability of 0.5A
minimum to 2.5A maximum (peak rating). The MBC25P11 driver operates with a DC voltage of 12VDC to
35VDC. The MBC25P11’s internal PG (pulse generator) has four different programmable motion profiles.
The MBC25P11 also has directional soft and hard limit switch inputs, a busy output and a clock output that
can be used for daisy chaining drivers together. The MBC25P11 driver features direction control and
motor current On/Off capabilities. The “Reduce Current Enabled” feature automatically reduces motor
current to 70% 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 MBC25P11 has various step resolutions that can be
implemented. These divisions range from 200 steps/rev to 1600 steps/rev. The bipolar drive configuration
handles 4, 6, and 8 lead step motors and is also equipped with short circuit, over temperature and crossover
current protection. The MBC25P11 communicates via RS232 communication. The easy to use Windows
software, SMPG10WIN, is used to directly set up to four different motion profiles.

Motion Profiles and Running the Pulse Generator
The programmable pulse generator has the ability to store up to four different motion profiles. The profiles
include a base speed (starting speed), a maximum speeds (running speed) and acceleration/deceleration.
The base speed has a range of 77-3500 Hz, the maximum speed has a range of 77 Hz-15 kHz, and the
acceleration/deceleration has a range of 1-255. A seperate command is used to control the ramp down
profile. The ramp down profile lets the user have the option to either ramp down to base speed and stop
(soft stop), or to hard stop once the Run input is released. The deceleration option is the same for all four
motion profiles.
There are “two ways” to get the pulse generator to run. The first way is to directly control it from the
computer with software. Once the motion profiles have been set, the pulse generator is ready to run. From
the software, the user can select which profile to run and then hit the run button. There are then several
different ways to stop motion. To ramp down to base speed and continue to run at base speed, a soft limit
command needs to be sent. This is done by either hitting the soft limit button or a physical limit switch
trigger of the soft+ or soft- depending on direction.  To stop all motion, a hard limit command needs to be
sent. This is done by either hitting the hard limit button or a physical limit switch trigger of the hard+ or
hard- depending on direction. The second way to make the pulse generator run is to activate the Run
input. When this input is activated, it looks to see what speed profile input is set. If no speed profile is set
then the default is Profile 1. To stop motion, release the Run input. When this input is released, the
deceleration option will then either ramp down to base speed and stop or just hard stop. If a soft+ or soft
limit switch is activated when the Run input is active, the pulse generator will ramp down to base speed
and keep running.  If a hard+ or hard- limit switch is activated when the Run input is active, the motor will
stop immediatley.

LEDs
When powered and operated properly, the status LED will be green.  When an 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 located in the “Motion Tab”. 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 section 5 for a list of the
error codes. When the pulse generator 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 defined 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 second. Very often,
the parity bit is included as an information or data bit. The MBCPG211only accepts a baud rate of 9600.
Inputs and Outputs
Inputs: All inputs (except limit inputs) are either pulled up to 5VDC or pulled down to 0VDC based on JP1.
For pullups place JP1 in position 1-2, for pulldowns place JP1 in position 2-3. A logic 0 activates inputs
that are pulled up, while a logic 1 activates an input that is pulled down. An unconnected input will always
remain inactive. (Refer to Dimensions and Jumper/Potentiometer Locations drawing for JP1)
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 can be overridden
by sending a + or - command to the pulse generator.  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 be enabled or energized. When this input is active, the
motor will be disabled or de-energized.
Run: When this input is not active, the pulse generator is stopped and will not output any pulses. When
this input is active the pulse generator will output pulses starting at the base speed rate and will ramp up
and output pulses at the max speed rate. When this input is released, the pulse generator will ramp down
to base speed and stop or hard stop depending on the deceleration option.
Speeds: These inputs are used to select one of the four profiles when the run input is activated. To use
profile 2, then activate Speeds 2, to use profile 3, then activate Speeds 3, and to activate profile 4, then
activate Speeds 4. Activate only one of these three inputs at once. If none of the inputs are active, then
profile 1 will be used. (Refer to both the Motion Tab and Wiring Diagrams for illustrations)
Soft Limits: These two inputs are active low and are controlled by the direction of the pulse generator.
When the pulse generator is running in the positive direction only soft+ will work. When the pulse generator
is running in the negative direction then only soft- will work. When pulled low the pulse generator will ramp
down to base speed and continue running until a hard limit is reached or the run input is released.
Negative Going Inputs (Pull Up) Positive Going Inputs (Pull Down)

Hard Limits: These two inputs are active low and are controlled by the direction of the pulse generator.
When the pulse generator is running in the positive direction only hard+ will work. When the pulse generator
is running in the negative direction then only hard- will work. When pulled low the pulse generator will stop
all pulses to the motor. To reverse off of a Hard Limit, release the Run input, change directions, and
activate the Run input again to move in the opposite direction.
External Clock Output: The external clock is the output of the internal pulse generator that can be used
to daisy chain other step motor drivers  together. This is an open collector output that is capable of sinking
10mA.
Busy Output:  This is an open collector output that is capable of sinking 10mA. It is current sinking when
the pulse generator is operating (sending pulses), and open when the pulse generator is not sending
pulses.

Setting the Output Current
The output current on the MBC25P11 is set by the on-board potentiometer R29 (Refer to Dimensions/
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:

Microstep Modes
The microstepping modes are set by using the software when the profiles are being setup. The ranges of
microstepping are 200, 400, 800, and 1600 steps per revolution in a 200 step/revolution step motor. To
set the divisor just select the divisor wanted (1,2,4, or 8). (Refer to Motion Tab Sheet)

Reducing Output Current
Reducing the output current is accomplished automatically depending on the current reduction setting in
the SMPG10WIN 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 paral-
leled 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. (Refer to Motion Tab
Sheet)

Step Motor Configurations
Step motors can be configured as 4, 6, or 8 leads. Each configuration requires different currents. Refer to
the lead configurations and the procedures to determine their output current.
WARNING! Step motors will run hot even when configured correctly. Damage may occur to the motor if a
higher than specified current is used. Most specified motor currents are maximum values. Care should be
taken to not exceed these ratings.
Determining Output Current
The output current used for the motor when microstepping is determined differently from that of a full/half
step unipolar driver. In the MBC25P11, 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 configuration of
the motor. There is a current adjustment potentiometer used to set the output current of the MBC25P11.
This sets the peak output current of the sine/cosine waves. The specified motor current (which is the
unipolar value) is multiplied by a factor of 1.0, 1.4, or 2.0 depending on the motor configuration (series,
half-coil, or parallel).
6 Lead Motors
When configuring a 6 lead motor in a half-coil configuration (connected from one end of the coil to the
center tap), multiply the specified per phase (or unipolar) current rating by 1.4 to determine the current
setting potentiometer value. This configuration will provide more torque at higher speeds when compared
to the series configuration.
When configuring the motor in a 
series configuration (connected from end to end with the center tap
floating) use the specified per phase (or unipolar) current rating to determine the current setting potenti-
ometer value.
4 Lead Motors
Multiply the specified series motor current by 1.4 to determine the current adjustment potentiometer
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.
