AMP's 3540MO step motor drive is a microstepping drive at 12,800 steps per revolution, step phase sequencer with MOSFET three state switching amplifiers and optoisolated circuits. The drive includes 5 optically isolated inputs, external speed control, tach output, and internal pots for accel/decel rate along with high/low speed range selection.

The amplifier regulates motor current by chopping at a constant, inaudible frequency. Phase current is selected from 32 levels by a DIP switch. Microstepping resolution is also selected by DIP switch.
