Chapter 1 Overview
1.1 Introduction
These Stepper Motor Actuators were designed for use with Thorlabs stages
compatible with modular drives (such as our NanoMax300 and 600 series). However,
they can be fitted to other stages by using a Modular Quick Connect Adapter (MCA1
for Ø3/8” mounting or MCA2 for Ø10mm mounting).
When driven by a Thorlabs BSC20x series stepper motor controller, this actuator is
capable of speeds as high as 4mm/sec and offers 8mm of travel. The powerful
stepper motor is capable of handling a load capacity of up to 21.8 Kg (48lb).
Bidirectional repeatability of 0.5µm.

Chapter 2 Operation and Maintenance
2.1 Initial Set Up
To ensure that a particular stage is driven properly by the system, a number of parameters
must first be set. These parameters relate to the physical characteristics of the stage being
driven (e.g. min and max positions, leadscrew pitch, homing direction etc.).
To assist in setting these parameters correctly, it is possible, using the APT Config utility,
to associate a specific stage type and axis with the motor controller channel. Once this
association has been made, suitable default parameter values are applied automatically
on boot up of the APT software.
To ensure correct operation, it is important to select the correct stage type for your
controller. If using a BSC20x series controller, select the appropriate ‘HS NanoMax’
option. If using a legacy BSC0xx or BSC10x controller, choose an option without the ‘HS’
prefix.
1) Shut down all applications using the APT s erver (e.g. APT User or y our own
custom application).
2) Run the APT Config utility - Start/All Programs/Thorlabs/APT Config/APT Config.
3) From the 'APT Configuration Utility' window, click the 'Stage' tab.
Fig. 2.1 APT Configuration Utility - Stage Tab
4) In the ‘Motor’ field, select the serial number of the stepper motor controller to be
configured (this number can be found on the rear panel of the controller unit).

5) In the ‘Stage’ field, select your actuator type from the li st displayed (e.g. HS
NanoMax 300 X Axis).
6) Click the 'Add Stage Association' button.
7) A default configuration is set at the factory and stored in the non-volatile memory
of the motor controller. The server reads in the stage and controller information on
start up. See the handbook supplied with the stepper motor controller for further
information.

2.3 Maintenance
After prolonged use, and particularly in applications where small movements are
continually repeated, the grease on the drive shaft may build up in ridges. This may
cause rough or noisy movement, vibration and excessive heating.
It is good practise to run the motor periodically from one end of travel to the other
several times in order to redistribute the grease.
Note
To ensure correct operation, it is important to select the correct stage
type for your controller. If using a BSC20x series controller, select the
appropriate ‘HS NanoMax’ option. If using a legacy BSC0xx or BSC10x
controller, choose an option without the ‘HS’ prefix.
Selecting an incompatible stage type could result in reduced velocity
and resolution. Furthermore, joystick functionality may be lost.

2.4 Using the MCA Modular Quick Connect Adapters
Modular quick connect adapters allow the DRV001 actuators to be fitted to stages
with standard mounting clamps (MCA1 for Ø3/8” mounting or M CA2 for Ø10mm
mounting).
Simply remove the circlip from the end of the drive rod, remove the washers, then
screw on the adapters.

2.5 Motor Connector Pin Out
The ‘Motor’ connector provides connection to the stepper motor controller. The pin
functions are detailed in Fig. 2.4.
