SECTION 3 STEP MOTOR DRIVER

MODEL – DPD60401

The DPD60401 will deliver a peak current of 5.5 Amperes per phase at 65 Volts, providing outstanding

motor performance. This advanced technology reduces ripple current while maintaining the 20kHz

chopping frequency in the motor, causing less heat in both the motor and drive.

MODE SELECT SWITCHES

The MODE SELECT SWITCHES are used to select the divisor of operation from divide by 2 up to divide

by 256. Microstep operations are recommended for those applications that specifically require this drive

technique, such as retrofitting existing microstep systems. Microstep applications are mainly used for very

slow speed operations that require high resolution or very smooth performance. This enhanced resolution

can only be accountable for positioning accuracy of a step motor typically ±5% of one full step when

dividing by 20 (step angle of .09°) or less. Anaheim Automation recommends the use of the bilevel drives

that have a divide by 2 (halfstep mode) for operations ranging in speeds higher than 2Khz, since

smoothness can easily be accomplished at this rate.

MICROSTEP SELECTION

The number of microsteps per step is selected by the dip switch(SW1). Table 6 shows the standard

resolution values along with the associated settings for these switches. The standard waveforms are

sinusoidal.
