January 2013 L010197 General Description The MBC05641 Microstep Motor Driver has an output current capability of 0.5 Amps minimum to 5.0 Amps maximum (Peak Rating). The MBC05641 driver operates from a DC voltage of 24-48 Volts. The inputs are optically isolated with a minimum sourcing of 7.0mA per input (+3.5VDC minimum to +24VDC maximum). The clock input is set to receive either positive or negative edge clocks with a maximum fre- quency of 400kHz. The MBC05641 driver offers direction control and motor current ON/OFF capabilities. The Reduce Current Enabled automatically reduces motor current to 50% 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 conditions (Red LED). With the MBC05641, various step resolutions can be implemented by the onboard dip switch. These divi- sions range from 200 steps per revolution to 12,800 steps per revolution. The bipolar drive confi guration handles 4, 6 and 8 lead motors. Protection devices have been added to this driver for Phase to Phase Short-Circuit conditions. Pin Descriptions The inputs on the MBC05641 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 7.0mA needs to be sourced or sinked through the opto-diode. This is done simply by placing a voltage of +3.5 to +24VDC 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 2. If sinking current, then all three anodes (+) should be tied together to the +voltage as shown in Figure 1. Provided on the MBC05641 is an external +5VDC out which can be used to power the inputs for sinking mode only. However, if you use this +5 voltage, isolation is not preserved.

January 2013 L010197 Dimensions Motor Selection The MBC05641 is a Bipolar Microstep Driver that is compatible with both Bipolar and Unipolar Motor Confi gurations, (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. Since the MBC05641 uses a constant current source drive technique, 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 potentiometer is set to the appropriate current level based on the motor being used. Higher voltages will cause the current to fl ow faster through the motor coils. This in turn means higher step rates can be achieved. Care should be taken not exceed the maximum voltage of the driver. Anaheim Automation offers a comprehensive line of step motors in 17, 23, 34 and 42 frame sizes. Contact the factory to verify motor/drive compatibility.

January 2013 L010197 Setting the Output Current The output current on the MBC05641 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 po- tentiometer value is as follows: Peak Current Potentiometer Setting Peak Current Potentiometer Setting 0.5A 0% 3.0A 60% 0.6A 10% 3.5A 70% 0.9A 20% 4.0A 80% 1.5A 30% 4.5A 90% 2.0A 40% 5.0A 100% 2.5A 50% -- -- Reducing Output Current Reducing the output current is accomplished by setting switch 1 of the DIP switch to the ON position and occurs approximately 1sec after the last positive going edge of the step clock input. The amount of cur- rent per phase in the reduction mode is approximately 50% of the set current. When the current reduction circuit is activated, the current reduction resistor is paralleled with the current adjustment potentiometer. This lowers the total resistance value, and thus lowers the per phase output current. Determine 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 MBC05641, 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 confi guration of the motor. There is a current adjustment potentiometer used to set the output current of the MBC05641. This sets the peak output current of the sine/cosine waves. The specifi ed motor current (which is the unipolar value) is multiplied by a factor of 1.0, 1.4, or 2.0 depending on the motor confi guration (series, half-coil, or parallel). Step Motor Confi gurations Step motors can be confi gured as 4, 6, or 8 leads. Each confi guration requires different currents. Refer to the lead confi gurations and the procedures detail above to determine their output current. WARNING! Step motors will run hot even when confi gured correctly. Damage may occur to the motor if a higher than specifi ed current is used. Most specifi ed motor currents are maximum values. Care should be taken to not exceed these ratings. Table 8: Output Current POT Settings Refer to Table 6 for specifi c motor current settings.
January 2013 L010197 8 Lead Motors Series Connection: When confi guring the motor windings in series, use the per Phase (or unipolar) cur- rent rating to determine the current setting potentiometer value. 4 Lead Motors Multiply the specifi ed 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. 6 Lead Motors When confi guring a 6 lead motor in a half-coil confi guration (connected from one end of the coil to the center tap), multiply the specifi ed per Phase (or unipolar) current rating by 1.4 to determine the current setting potentiometer value. This confi guration will provide more torque at higher speeds when compared to the series confi guration. When confi guring the motor in a series confi guration (connected from end to end with the center tap fl oating) use the specifi ed per Phase (or unipolar) current rating to determine the current setting potenti- ometer value. Parallel Connection: When confi guring the motor windings in parallel, multiply the per Phase (or unipolar) current rating by 2.0 to determine the current setting potentiometer value.

January 2013 L010197 Note: After the current has been determined, according to the motor connections above, use Table 8 to choose the proper setting for the current setting potentiometer. Connecting the Step Motor Phase 1 and Phase 3 of the step motor are connected to pins 1 and 2 on connector TB2. Phase 2 and Phase 4 of the step motor are connected to pins 3 and 4 on connector TB2. The Motors case can be grounded to pin 5 on connector TB2. Refer to Figures 1 & 2 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.
