AMP's 3540M step motor drive is a microstepping drive from 400 to 12,800 steps per revolution, with custom resolutions available upon request, step phase sequencer with MOSFET three state switching amplifiers and optoisolated circuits. The drive also includes an automatic feature to lower motor current by 50% anytime the motor is left at rest for more than one second. This feature can be disabled. Additional there is a switch selectable self-test which rotates the motor 1/2 revolution in each direction at 100 steps/second.

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.
