Description
The 3535O step motor driver is a full or half stepdrive, step phase sequencer with MOSFET threestate switching amplifiers and optoisolated circuits.This drive has a built in ramping pulse generator(oscillator) with adjustable speed, acceleration anddeceleration. Oscillator speed range is 400–5,000Hz. Speed can be set from on-board trimpot or ex-ternal 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 motoraccelerates to a preset speed and slews. Loweringthe input signal causes the drive to decelerate torest.
The amplifier regulates motor current by choppingat a constant, inaudible frequency. Phase current isselected from 32 levels by a DIP switch.
