Chapter 1 Overview

1.1 Description

The NanoRotator NR series rotation stage provides arc-second resolution when

driven from a microstepping stepper motor controller. The low profile design,

measuring just 55mm high, is made possible by the use of two compact precision

bearings. The rotating carriage of the stage provides continuous rotation of load of up

to 50kg and has a 50mm clear aperture to allow the passage of the optical path

directly through the stage. The main body of the stage is made from lightweight

aluminum and can attach directly to an optical table, or be mounted at any orientation

via the 9 mounting holes provided along four surfaces of the device. A worm gear

assembly is used to transfer the rotary motion of the stepper motor into rotary motion

of the carriage. There is a mechanical reduction in this gear assembly that provides

one revolution of the carriage for every 66 turns of the stepper motor.

An electrical limit switch has been fitted to allow the user to datum the Nanorotator but

this limit switch is only active in the negative direction. This means that the

Nanorotator will run to infinity in the positive direction, but will not pass zero in the

negative direction. If a movement is programmed that takes the manipulator past its

negative limit, the limit switch will trip and stop the motor. It is then only be possible to

execute moves in the positive direction until the limit switch is no longer tripped.

The Nanorotator is designed specifically to operate with the BSCxxx benchtop

stepper motor controllers or the MST60x modular stepper motor control unit.

For further information on these controllers, please refer to the relevant manuals.

1.2 Accessories

Several mounting plates are available which allow the stage to be fixed to an optical

table in either horizontal or vertical configurations. The adapter plates allow device

holders to be fitted to the rotating platform. The stage can also be mounted onto one

of our NST or TravelMax long travel stages.

NR360SP1 - Table Mounting Plate: This adapter plate is used to mount the NR360S

rotation stage to a large flat surface such as an optical table. The 10mm thickness

provides clearance for the stepper motor body which extends below the bottom

surface of the stage, and ensures that the stage sits flat on the mounting surface.

NR360SP2 - Vertical Mounting Bracket: Allows the NR360S rotation stage to be

mounted in a vertical orientation.

NR360SP4 - Grooved Carriage Plate: This adapter plate provides an easy means to

integrate all of the miscellaneous accessories from our fiber launch systems product

line. These accessories include optical mounts, tip-tilt mounts, as well as fiber

holders. Please see the Accessories tab on the main NR360S stage page for more

details on the range of accessories available.

NR360SP5 - Mounting Plate: This mounting plate allows the NR360S stage to be

attached to a LNR50 TravelMax, or NRT stage.

NR360SP8 - SM1 Apapter Plate: This mounting plate features an SM1 threaded

through hole and allows 1" optics and our SM1 product line to be mounted to the

NR360S.

NR360SP9 - 1/4"-20 and 8-32 Threaded Adapter Plate: Provides numerous options

for attaching devices to the NR360S: includes 17 1/4"-20 Mounting holes, and four 8-

32 fixing holes.

NR360SP9/M - M6 and M4 Threaded Adapter Plate: Provides numerous options for

attaching devices to the NR360S: includes 17 M6 Mounting holes, and four M4 fixing

holes.

Chapter 3 Operation

3.1 Using the Nanorotator

3.1.1 Background

The hybrid stepper motor used in the actuator, with its rotor that consists of 50

individual magnetic teeth, is ideally suited for micro-stepping applications. Aside from

the obvious increase in resolution provided by increasing the steps per revolution

from 200 to 409,600, micro-stepping also ensures smoother low speed motion by

allowing the discrete 1.8º step size, which produces vibrational noise, to be reduced

to much smaller steps with inherently lower resultant vibrational noise.

The rotation stage utilizes a worm gear assembly which provides one complete

rotation of the platform for every 66 turns of the stepper motor. When used with the

APT™ Series stepper motor controller, the stepper motor provides 409,600 steps per

revolution resulting in 66 x 409,600 steps per revolution of the stage. This results in a

360/(66 x 409,600)° or 13.3 x 10-6 degrees of platform rotation per microstep.

The Nanorotator is connected to the Stepper Motor Controller via a flying lead

terminated in a D-type type connector. A 3m extension cable (PAA613) is also

supplied.

Manual control of the Nanorotator can be achieved by switching off the drive to the

motors. Please refer to the relevent controller manual.

3.2 Selecting the Stage Type

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 to associate a specific stage

type and axis with the motor controller channel. Once this association has been made, the

server applies automatically, suitable default parameter values on boot up of the software.

Caution

The relevant stepper motor controller or channel must be switched off/disabled

before the Nanorotator is plugged in or unplugged. Failure to switch the controller

off may result in damage to either the controller, the Nanorotator, or both.

Caution

The electrical limit switch does not operate when the motor is being turned by hand.

Care must be taken to to avaid fouling if the drive is turned past the limit switch.

6) 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).

7) In the ‘Stage’ field, select ‘HS NanoRotator’ from the list displayed.

8) Click the 'Add Stage Association' button.

9) 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

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 ‘HS NanoRotator’ 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.

Note

In applications where continuous rotation is necessary for prolonged periods, it is

possible that the position register inside the controller could overflow. In this case,

the stage will continue to operate, but the position readout is no longer accurate.

Homing the stage will restore the positional accuracy.
