Chapter 2 Overview
2.1 APT Rack System Description
2.1.1 Introduction
Thorlabs has an extensive range of one-, two- and three-axis controllers for stepper
motor and piezo actuator control. Increasingly, production of optoelectronic
components requires fully automated or semiautomated control of a large number of
mechanical stages. In such applications, it is often more convenient to use a modular
system of controllers to drive a modular system.
The Thorlabs Modular Motion Control System has been developed to meet the
challenges of the modern optoelectronic production environment and provides
unsurpassed ease of installation, reconfiguration, flexibility and upgradability.
The modular rack system provides a highly functional 12 channel platform within the
‘footprint’ of a 4U high, 19” wide enclosure. With a unified power supply and a USB
communications interface, the APT rack system is easily incorporated into larger
custom applications. The MMR601 Rack is supplied without a cover, ready for
installation into a standard 19 in. frame. The MMR602 is supplied with a cover and
rubber feet for benchtop use.
2.1.2 Building Larger Scale Systems
The unrestricted configuration flexibility offered by the APT rack allows any
combination of the 2-channel APT stepper motor controller, piezoelectric driver and
NanoTrak control modules to be fitted for specific nanopositioning and alignment
applications. For example, a system configured to operate our APT606 6-axis
nanopositioning stage, which has six stepper motors and six piezoelectric actuators
with displacement sensors, would require 12 channels of motion control. Using three
stepper motor modules, each with two channels, provides the motor control; using two
piezoelectric controller modules and one NanoTrak controller module would power all
6 of the piezoelectric actuators while also taking advantage of the position sensors.
Additionally, the NanoTrak module provides the full range of features offered by a fully
operational auto-alignment system. All this functionality fits into the single chassis that
measures just 4U in height.
Please see the documentation supplied with the various module products for further
details.
