MAC 5000

Focus Drive Microstepper Module

Overview

Focus control presents different requirements for motor control; precise, high

resolution positioning with a high throughput requirement. This module supports

all LEP focus drive motors in either open or closed loop congurations. Digipot

and joystick input is available for manual control.

I/O Connections

A standard LEP pinout DB-15 female connector supplies the stepper motor

control signals. Also provided is a separate DB-15 connector for encoder input . A

mini-DIN connector has connections for auxiliary end-limit input.

An auxiliary internal communication port for inter-module connection with

the 73005085 Autofocus Processor module is available.

Inputs for dedicated analog and digital joystick are provided on a mini-DIN

connector.
