AMP's 2035O step motor drive is a full or half drive, step phase sequencer with three state switching amplifiers and optoisloated circuits. The drive has a built in ramping pulse generator (oscillator) with adjustable speed, acceleration and deceleration. Oscillator speed range is 0-5,000 Hz. Speed can be set from on-board trimpot or external pot.

A jumper allows you to select the internal oscillator. In oscillator mode, the pulse input becomes a run/stop signal: when this signal is set high, the motor accelerates to a preset speed and slews. Lowering the input signal causes the drive to decelerate to rest.

The amplifier regulates motor current by chopping at a constant, inaudible frequency. Phase current is selected from 16 levels by a DIP switch.
