8 Lead Motors
Series Connection: When configuring the motor windings in series, use the per phase (or unipolar)
current rating to determine the current setting potentiometer value.
Parallel Connection: When configuring 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 potenti-
ometer setting table  to choose the proper setting for the current setting potentiometer.
Connecting the Step Motor
The MBC25P11 is designed to accept either one or two motors. For wiring of the motor refer to the pages
containg the connector descriptions and hookup diagrams.
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, 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 short circuit, over temperature and cross 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 airflow should be added to prevent temperature to exceed recommended temperature limit.

Functions
Soft Limit Switches: These switches cause the pulse generator to ramp down to the base speed before
encountering a hard limit switch. Hard Limit Switches: When a hard limit switch is encountered, the pulses will stop. Hard limits are
intended as an emergency stop for your system.
Profile Inputs: These inputs are used to select the specified speed profile. These inputs are used in
conjuction with the Run input.  If no profile inputs are selected then profile 1 will be used. Only 1 input
should be activated at a time.
Run: Triggering this input will cause the pulse generator to start. The pulse generator will use the given
speed profile and start at base speed and ramp up to max speed.  The motor will run at max speed  until
a soft limit, hard limit, or the stop run is released. If the pulse generator is running at max speed when the
stop/run input is released then it will either stop hard or ramp down to base and stop depending on the
setting of the ramp down profile. Speed Profiles: The pulse generator will accept up to four different speed profiles. Each profile has it own
programmable Accel/Decel, Base speed, and Max speed. Theses values are stored in EEProm for
standalone use and must be programmed before the pulse generator can run.
Max Speed: The max speed is the top speed the user wants the pulses to run at. This speed must always
be equal or greater than the base speed. It is entered directly as the number of steps/second. The differ-
ent max profiles are stored in EEprom for standalone use. (Range: 77 to 15000) Acceleration/Deceleration: The acceleration and deceleration are by default the same value. This func-
tion controls the time that the motor will take to move from base speed to max speed. The higher the
value, the slower the motor will accelerate. The same principal applies for the deceleration which is con-
trolling the time it takes to go from maximum speed to base speed. The higher the value, the slower the
pulses will decelerate.The different accel/decel profiles are stored in EEprom for standalone use. (Range:
1 to 255)
Base Speed: The base speed is the speed at which motion starts and stops. It is entered directly as the
number of steps per second. This speed must always be less than the max speed. The different base
profiles are stored in EEprom for standalone use. (Range: 77 to 3500) Ramp Down Option: When this option is off the pulse generator will stop hard when the Run input is
released. If this option is on, then the pulse generator will ramp down to base speed and stop when the
Run input is released.
Direction Input: If this input is open then the unit will be running in the clockwise direction. If this input is
active then the unit will be running in the counterclockwise direction. This pin can be overridden by the
programmable software direction. It will activate the direction output when the pin is changed.
Busy Output: This output will be pulled low when the pulse generator is operating. It is an open drain
output so when the pulse generator is not running the pin is open.

Direct mode is used to directly control the motion for real time movements through serial communication.
The pulse generator has 14 commands which are easy to remember for direct movement of a step motor.
COM Port Settings
Baud Rate:9600
Parity:None
Data Bits:8
Stop Bits:1
Flow Control:Xon/Xoff
Unit Selection
In order to select a unit the @ command followed by 0 (address of the unit) must be sent.
NOTE: There should be no spaces between the @ and the 0.
How to select the unit:
@0 (Unit is selected)
How to get a response from the unit:
@0$ (Carriage Return)
After the $ command, the pulse generator will return a SMPG10 + the current version number.
Note: In direct talk mode each command is followed by a carriage return.
The unit communicates in half duplex mode, therefore proper setup of hyper terminal is necessary to view
characters, if characters are to be echoed back to the screen.

#L010128June 2002
A - Acceleration/Deceleration
Format: A#_[value] - where # is the speed profile number 1 thru 4
Sample: A1_255 Accel of profile 1 equals 255
Description: This command sets the acceleration profile which can be an integer value be-
tween 1 and 255. The lower the value the faster the pulse acceleration, so a 1 is
the fastest profile and 255 is the slowest. These values are saved in the EEProm
for standalone use.
Range: 1 - 255
B - Base Speed
Format: B#_[value] - where # is the speed profile number 1 thru 4
Sample: B3_100 Base Speed of profile 3 equals 100
Description: This command sets the base (start) speed for motion. This value must be set be-
fore motion begins and be less then the maximum speed. The pulses will ramp
down to this speed after a soft limit is triggered and run at this speed until a hard
limit is triggered. These values are saved in the EEProm for standalone use.
Range: 77 - 3500 $ - Version Number Register
Format : $
Description: This command requests the pulse generator to return the version number.
! -  Error Codes Register
Format : !
Description: This command requests the pulse generator to get the current error code and print
it to the screen.
C - Current Reduce Option
Format: C# - where # is 0 or 1
Description: This command enables the driver to reduce current after pulses are done being
sent. A 1 will enable current reduction, and a 0 will disable current reduction. This
value is saved in the EEProm for standalone use. +/- -  Direction
Format: + or -
Description: This command sets the direction output. A “+” sets the output to clockwise, and a
“-” set the output to counterclockwise. This must be done when the pulses are
not running. This value is saved in the EEProm for standalone use. 
						

							18
#L010128June 2002
G - Go Slew (Run)
Format : G# - where # is the speed profile number 1 thru 4
Description: This command will send clocks out to the pulse generator. The only command
that can stop the clocks is H (stop motion). The S(soft limit) command will make
the pulses go from max speed to base speed. Motion can also be stopped by
using the limit switch inputs. The ramp profile is specified by the B (base speed),
M (max speed), and A (acceleration/deceleration) commands.
H - Hard Limit or Stop Motion
Format: H
Description: This command will stop all motion.  It can only be used when pulses are running
M -  Max Speed
Format: M#_[value] - where # is the speed profile number 1 thru 4
Sample: M2_10000 Max Speed of profile 2 equals 10000
Description: This command sets the maximum (running) speed for motion. This value must be
set before motion begins and be equal or greater than the base speed. The motor
will run at this speed until a soft limit or a hard limit is triggered. These values are
saved in the EEProm for standalone use.
Range: 77 - 15000
R - Microstepping Resolution
Format: R# - where # is 1, 2, 4, or 8
Description: This command enables the user to select the desired resolution for the microstepping
driver.  Divisions for the driver are Full step (1), Half step (2), Quarter step (4), and
Eighth step (8). This value is saved in the EEProm for standalone use.
S - Soft Limit
Format: S
Description: This command will cause the pulse generator to ramp down to base speed and run
until a hard limit is activated. It can only be used when pulses are running. D - Decceleration Option
Format: D# - where # is 0 or 1
Description: This command enables the pulse generator to ramp down to base speed before
stopping when using the external Run/Stop input.  A 1 will enable the pulses to
ramp down to base speed and stop, and a 0 will disable ramp down causing the
pulse generator to hard stop at maximum speed. This value is saved in the EEProm
for standalone use.

#L010128June 2002
V - Verify
Description: This command can be used with most commands to verify the register contents.
This is a read only command. Valid Commands are: A, B, C, D, M, R, and +.
Format: V[command]
This format is good for C, D, R, and +.
C - If a 1 is sent back then the driver is in reduced current mode.  If a 0 is sent back
then the driver is not in reduced current mode.
D - If a 1 is sent back then the pulse generator will ramp down to stop when the Run/
Stop input is released.  If a 0 is sent back then the pulse generator will stop hard
when the Run/Stop input is released.
R - If a 1 is sent back then the driver is in Full step mode. If a 2 is sent back then the
driver is in Half step mode. If a 4 is sent back then the driver is in Quarter step If
mode. If an 8 is sent back then the driver is in Eighth step mode.
+ - If a 1 is sent back then the direction is clockwise.  If a 0 is sent back then the
direction is counterclockwise.
Sample: VD Verification of Direction is prompted.
Format: V[command]# - where # is the speed profile number 1 thru 4
This format is good for A, B, and M.
A# - Verify Acceleration/Decceleration for given speed profile.
B# - Verify Base speed for given speed profile.
M# - Verify Max speed for given speed profile.
Sample: VB3 Verification of Base Speed in Profile 3 is prompted.
