Introduction
The MBC10641 Microstep Driver has an output current capability of 1.5 Amps minimum to 10.0 Amps
maximum (Peak Rating). The MBC10641 driver operates with either a transformer, whose input can be
wired from 90-265 VAC or a DC voltage of 30-85 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 MBC10641 driver
offers direction control and motor current ON/OFF capabilities. The Reduce Current Enabled automati-
cally reduces motor current to 70% of set value after the last step is made (1sec delay). The driver has
built-in features to indicate power on (Green LED), Clocks being received (Yellow LED) and fault condi-
tions (Red LED).
With the MBC10641, 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. The bipolar drive configura-
tion handles 4, 6 and 8 lead motors. Protection devices have been added to this driver for Phase to Phase
Short-Circuit, Motor Mis-Wire, Over-Temperature and Over-Voltage conditions.
Pin Descriptions
The inputs on the MBC10641 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 simply by
placing a voltage of +5 to +24 VDC across the two inputs of the opto-diode. If sourcing current into the
inputs, then all three cathodes (-) should be tied together and grounded as shown in Figure 4. If sinking
current, then all three anodes (+) should be tied together to the +voltage as shown in Figure 3. Provided
on the MBC10641 is an external +5VDC out, which can be used to power the inputs for sinking mode only.
However if you use this voltage, isolation is not preserved.

Power Supply Requirements
It is recommended that the MBC10641 be powered by the AA3621 corresponding transformer as speci-
fied. The AA3621 transformer has an input line voltage ranging from 90-265VAC, two high-voltage wind-
ings (yellow-yellow/black), and a logic winding (orange). The high voltage windings can be used to power
two drivers or put into parallel to power one. If powering one driver, connect the two yellow wires together
and connect the two yellow/black wires together and plug into the quick disconnects (QD1 and QD2,
shown on Figures 3 & 4) located on the front face of the driver. When connecting two drivers, connect one
yellow wire and one yellow/black wire (they come out together in pairs), and connect them to the quick
disconnects (QD1 & QD2) located on the front face of each driver. When using the AA3621 transformer,
the nominal voltage of the MBC10641 will be 80VDC. In Figure 1, the transformer wiring is shown for
different line voltages ranging from 90-265VAC. A DC input of 30-85 volts can also be used to power the
drive. To connect the DC to the drive, place the ground wire on the QD2, and the plus wire on QD1. It is
recomended that fully insuated female quick connect connectors (Panduit # DNF14-250FIB) be used to
connect to QD1 and QD2.

Motor Selection
The MBC10641 is a Bipolar Microstep Driver that is compatible with both Bipolar and Unipolar Motor
Configurations, (i.e. 8 and 4 lead motors, and 6 lead center tapped motors).
Step motors with low current ratings and high inductance will perform better at low speeds, providing
higher low-end torque. Motors with high current ratings and low inductance will perform better at higher
speeds, providing more high-end torque. Higher voltages will cause the current to flow faster through the
motor coils. This in turn means higher step rates can be achieved. Care should be taken not to exceed the
maximum voltage of the driver.
Since the MBC10641 is a constant current source, it is not necessary to use a motor that is rated at the
same voltage as the supply voltage. What is important is that the MBC10641 is set to the appropriate
current level based on the motor being used.  Refer to the following chart for setting the current potentiom-
eter based on the current code in the part number of the motor. Examples of motor part numbers are
shown below. Anaheim Automation offers a comprehensive line of step motors in 14, 17, 23, 34 and 42
frame sizes. Contact the factory to verify motor compatibility with the MBC10641.

Microstep Selection (SW1 Settings)
Switches 2, 3 and 4, of the DIP switch select the number of microsteps per step. Table 6 shows the
standard resolution values along with the associated positions for the select switches. The standard wave-
forms are sinusoidal.
Setting the Output Current
The output current on the MBC10641 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:

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.
Reducing Output Current
Reducing the output current is accomplished by setting switch 1 of the DIP switch to the ON position and
occurs 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 70% of the set current. When the current
reduction circuit is activated, the current reduction resistor is paralleled with the current adjustment poten-
tiometer. This lowers the total resistance value, and thus lowers the per Phase output current.
Determining Output Current
The output current for the motor used when microstepping is determined differently from that of a full/half
step unipolar driver. In the MBC10641, 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 MBC10641.
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).
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.
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. 
						

							#L010143November 2003
4 Lead Motors
Multiply the specified series motor current by 1.4 to determine the current adjustment potentiometer
value. Four 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.
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 unipo-
lar) 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 Table 3 to
choose the proper setting for the current setting potentiometer.

Connecting the Step Motor
Phase 1 and 3 of the Step Motor is connected between pins 1 and 2 on the motor connector (TB2).  Phase
2 and 4 of the Step Motor is connected between pins 3 and 4 on the motor connector (TB2).  The motors
case can be grounded to pin 5 on the motor connector (TB2). Refer to Figures 2, 3 & 4 for 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, switch the
wires on Phase 1 and  Phase 3.
WARNING: Do not connect or disconnect motor wires while power is applied!
Short-Circuit, Mis-Wire, and Over-Current Conditions
If it is found that there is a condition that causes on over current in the driver phase transistors, the Red
LED will turn on solid and power will be shut off to the motor.  To reset the drive turn power off, check
wiring, and turn power back on.
Over-Temperature and Over-Voltage Conditions
If it is found that there is an over temperature on the internal heat sink, or an over voltage on the motor bus
voltage,  the Red LED will blink and power will be shut off to the motor.  To reset the drive turn power off,
check wiring, and turn power back on.
