Microstepping: Step resolutions can be implemented by the on-board dip switch. These divisions ranges
are 1, 2, 4, and 8 which offer 200 steps per revolution to 3200 steps per revolution with a standard 200
step/revolution step motor.
Bipolar Drive: The bipolar drive configuration handles 4, 6, and 8 lead motors.
Reduced Current Enabled: Automatically reduces motor current 70% after last step (20msec delay).
Built In Features: Status LEDs to indicate power on (Green LED), clocks being received (Yellow LED),
fault detection (Red LED) and an optically isolated fault output that conducts when a fault is detected. Both
protection and detection devices have been added to this driver for phase-to-phase short-circuit, motor
cable mis-wire, over temperature and over voltage conditions.
Power Supply Requirements
The MLP07081 is directly connected to 120VAC (60/50Hz) through the standard molded plug for AC
Power. This AC voltage internally generates a bus voltage of 160VDC for the step motor. This 160VDC
voltage provides superior torque and power over other drivers.

TB1: 8 Pin (MLP07081) or 10 Pin (MLP07081-5) Terminal Description Pin Descriptions
The inputs on the MLP07081 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 activate the input,
a voltage needs to be applied across the opto-diode to source or sink current through the opto-diode. This
is done simply by placing a voltage of +5VDC to +24VDC across the two inputs of the opto-diode. If
sourcing current in to the inputs, then all three cathodes (-) should be tied together and grounded as
shown on the following page. If sinking current, then all three anodes (+) should be tied together to the
+voltage as shown on the following page. Provided on the MLP07081-5 is an isolated +5VDC, 100mA
output which can be used to power the inputs for sinking mode only. The MLP07081-5 therefore has two
additional pins ISO 5V OUT and ISO GND on TB1.

Motor Selection
The MLP07081 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). Since the MLP07081 is a
constant current source, it is not necessary to use a motor that is rated at 160V which is the motor supply
voltage. What is important is that the MLP07081 is set to the appropriate current level based on the motor
being used. The higher voltage of this drive will cause the current to flow faster through the motor coils.
This in turn means higher step rates and more power can be delivered to the application.
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.
Anaheim Automation offers motor cable, making hookups quick and easy!

Setting the Output Current
The output current on the MLP07081 is set by the on-board 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:
Reducing Output Current
Reducing the output current is accomplished by setting switch 3 of the DIP switch to the ON position and
occurs approximately 20msec. 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 by a sine/cosine output function.
The output current for a given motor is determined by the motors current rating and the wiring configura-
tion of the motor. There is a current adjustment potentiometer used to set the output current of the
MLP07081. This sets the peak output current of the sine/cosine waves. Step motors can be configured
with 4, 6, or 8 leads. Each configuration requires different currents. Refer to the lead configurations and
the procedures to determine their output current. 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).
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.
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 potentiometer value.
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 the table
on page 8 to choose the proper setting for the current setting potentiometer.
