A resistor between this pin and pin 2 (Connector P2, Current Adjust) will proportionately reduced the current in both windings (1 second after the last positive going edge of the step clock input). The amount of current reduction will depend on the value of the resistor used.

  • Page 6: Determining Output Current

    DETERMINING OUTPUT CURRENT The output current for the motor used when microstepping is determined differently from that of a half/full unipolar driver. In the MDM40001, 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 configuration for how the motor is hooked up.

  • Page 7: Step Motor Configuration

    STEP MOTOR CONFIGURATIONS Step motors can be configured as 4, 6, or 8 leads. Each configuration requires different currents. Shown below are different lead configurations and the procedures to determine their output current. 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) use the specified per Phase (or unipolar) current rating to determine the current adjustment resistor value.

    DOES NOT exceed the maximum driver input voltage because of line voltage fluctuations. It is recommended that a input line filter be used on the power supply to limit voltage spikes to the driver. #L010068 Anaheim Automation Step Motor Selection Guide Part Number 23D102 23D104...

  • Page 9: Microstep Selection

    MICROSTEP SELECTION The number of microsteps per step is selected by switches 1, 2, 3, and 4 of the DIP switch. Table 5 shows the standard resolution values along with the associated inputs for the select switches 1, 2, 3 and 4. The standard waveforms are sinusoidal. Resolution Steps/ Select 1...

  • Page 10: Timing

    TIMING The Direction and Microstep Resolution Select inputs are synchronized with the positive going edge of the Step Clock input. When the Step Clock input goes high, the Direction and Microstep Select inputs are latched and further changes to the inputs are ignored until the next rising edge of the Step Clock input.
