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 MBC25P22 is designed to accept either one or two motors. For wiring of the motor refer to the pages
containing 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
Max1/Max2 Input: This inputs is used to select the specified speed profile. These inputs are used in
conjunction with the Run input. Max1 selects profile 1 and Max2 selects profile 2.
Run: Triggering this input will cause the pulse generator to start. The pulse generator will use the selected
speed profile and start at base speed and ramp up to max speed.  The motor will run at max speed  until
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.
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.
Reduce Current Option: When this option is on the motor will receive 70% of its set current when the
pulses stop. When this option is off the motor will receive 100% of its set current when the pulses stop.
Microstep Resolution: These options will set the divisor for both drivers. The options are 1 (200 steps/
rev), 2 (400 steps/rev), 4 (800 steps/rev) or 8 (1600 steps/rev)
Analog Speed Option: When this option is on the pulse generator will calculate the max speed to use
when motion is started. The maximum speed will be calculated based upon the percentage of the poten-
tiometer input and the percentage between the upper and lower inputs
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. (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: 152 to 5000)
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: 152 to 50000)
Lower Analog Limit: The lower analog limit is the speed at which the max speed will calculate when the
potentiometer is at its lower position (0VDC).
Upper Analog Limit: The upper analog limit is the speed at which the max speed will calculate when the
potentiometer is at its upper position (5VDC).
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.
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:38400
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 SMPG20 and the current revision number.
Note: In direct talk mode each command is followed by a carriage return (enter command).
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.

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.
A - Acceleration/Deceleration
Format: A#_[value] - where # is the speed profile number 1 or 2
Sample: @0A1_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 or 2
Sample: @0B2_200 Base Speed of profile 2 equals 200
Description: This command sets the base (start) speed for motion. This value must be set be-
fore motion begins and be less than 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: 152 - 5,000
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.

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.
E - Analog Input Option
Format: E# - where # is 0 or 1
Description: This command enables the pulse generator to calculate the maximum speed based
upon the potentiometer settings.  A 1 will enable the analog speed and a 0 will
disable the analog speed and use the entered maximum speed. This value is saved
in the EEProm for standalone use.
G - Go Slew (Run)
Format : G# - where # is the speed profile number 1 or 2
Description: This command will send clocks out to the pulse generator. The only commands
that can stop the clocks are H (stop motion) and the S(soft limit) command.
H - Hard Limit or Stop Motion
Format: H
Description: This command will stop all motion.  It can only be used when pulses are running.
L - Lower Analog Speed Limit
Format: L#_[value] - where # is the speed profile number 1 or 2
Sample: @0L2_25000 Lower Analog Speed of profile 2 equals 25000
Description: This command sets the lower analog speed limit speed for motion. This value must
be set before motion begins and be equal or greater than the base speed and less
than or equal to the upper analog speed limit. This value is used as the lower
threshold when calculating the analog maximum speed. These values are saved in
the EEProm for standalone use.
Range: 152 - 50,000
