描述 Description

The 2035O step motor driver is a full or half step

drive, step phase sequencer with three state

switching amplifiers and optoisolated circuits.

This 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.
