Description
The
2035 step motor driver contains a full and half step phase sequencer, two
switching ampliers and optoisolation circuits. This driver also includes an
automatic feature to lower motor current anytime the motor is left at rest for
more than one second.
The ampliers regulate motor current by chopping at a constant, inaudible frequency. Phase current is selected from 16 levels by a DIP switch. Full or half step operation is also selected by the DIP switch.
The 2035 is a PC board mounted on an aluminum angle heat transfer chassis. Mating heat sink available for stand alone operation.
