Each time the step motor driver receives a pulse, the step motor moves one step. If the driver receives 200 pulses, the motor moves 200 steps. The motor steps at the same frequency as the clock pulses. FIGURE 1: Step Motor Driver General Description The BLD72 is a step motor driver that can drive motors rated from 1 to 7 amps/phase (unipolar rating). It can handle 6 lead and 8 lead motors. This driver features a unipolar bilevel (or dual voltage) drive technique with short and open circuit prote

2000 Steps/Revolution . On-Board Programmable Simple Indexer with 2 motion profiles . Pulses From 1Hz to 50kHz . Directional Soft and Hard Limit Switch Inputs . Complete Output . Busy Output . Motor On/Off Input and Automatic Current Reduction . Short Circuit Protection Introduction The MBC10SI1 is an low cost single axis step motor driver integrated with a programmable simple indexer. The MBC10SI1 microstep driver/pulse generator has an output current capability of 1.5A minimum to 10.0A maximum

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 conf

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 automatically reduces motor current t
