Precautions

Zaber's autodetect peripheral axes are designed to be used effortlessly with Zaber's line of autodetect controllers. The ASR includes onboard memory that allows Zaber's controllers to autodetect the model and set reasonable parameters. See the Protocol Manual for more information on how to modify the settings. Damage to the axis may result if the settings are not correct. To use your Zaber peripheral with a third-party controller, review the motor, sensor, and encoder specifications and pin-outs carefully.



Zaber’s motion control devices are precision instruments and must be handled with care. In particular, moving parts must be treated with care. Avoid axial loads in excess of the rated thrust load, axial and radial impact, dust and other contaminants and damage to the lead screw thread. These will reduce the performance of the device below stated specifications.

Noise Emissions

The A-weighted emission sound pressure level (SPL) of this device does not exceed 70 dB(A) during intended use.

The A-weighted emission sound pressure level (SPL) of this device may reach up to 79 dB(A) if the stage is stalled.

Conventions used throughout this document

  • Fixed width type indicates communication to and from a device. The symbol indicates a carriage return, which can be achieved by pressing enter when using a terminal program.
  • An ASCII command followed by (T:xx) indicates a legacy T-Series Binary Protocol command that achieves the same result. For example,
    move abs 10000 (T:20:10000) shows that a move abs ASCII command can also be achieved with Binary command number 20.
Not all ASCII commands have an equivalent Binary counterpart.

Device Overview

AutoDetect

Your ASR peripheral is equipped with AutoDetect, a feature that allows a Zaber controller to automatically configure its settings for the peripheral when it is connected.

Tip lightbulb symbol.png Important: The controller should always be powered down before disconnecting or connecting your ASR peripheral.

To connect the peripheral to a controller:

  1. Power off the controller.
  2. Connect the ASR peripheral.
  3. Power on the controller.
  4. The controller will activate the peripheral shortly after it is powered on.

See the Zaber controller user manual for more details on peripheral activation and control.

Connectors

Recommended controller(s) for your ASR peripheral are provided in the product specifications. Zaber's controllers and peripherals are designed for ease of use when used together. Optimal settings for each peripheral are automatically detected by Zaber's controllers when the device is connected.

For reference, the pinout for the peripheral cable connectors is shown below:

Alternate Controllers

The ASR can be controlled by any 2-phase stepper motor controller with limit sensor input. We do not recommend using your own controller unless you are familiar with how to control a stepper motor with hall sensor limit switches. Damage to the device due to incorrect wiring is not covered by warranty.

Motors

For motor information see the ASR product page

Limit Sensors

Hall effect sensors are used in the ASR as home and away sensors. The Hall sensors used are part number A1120LLHLT-T made by Allegro. Click here for data sheet. Your controller should be configured so the stage stops immediately (quick deceleration) when the sensors are triggered.

  • PCB wire colour code:
    • 5 Vdc input - red
    • Home signal - yellow
    • Away signal - white
    • Ground - black

The Hall sensor has an open-collector output. The default output is high impedance when the Hall sensor is not active. When the sensor detects a magnet, the Hall sensor pulls the output low to ground.

Hall sensor wiring diagram.png

If you are not using a Zaber controller, ensure that your controller has a pull-up resistor on the output line of each Hall sensor as shown in the diagram. The bypass capacitor is optional, but may help to eliminate false triggering in noisy environments. The typical value for the pull-up resistor (RLOAD) is 10 kΩ and for the bypass capacitor is 0.1 uF to 1 uF. The larger the capacitance, the better the noise filtering but the slower the response time.

Installation

Shipping Plate Removal

The (X-)ASR205B205B and (X-)ASR305B305B stages are fitted with sheet metal plates to prevent shock loads from the stage during shipping. Follow the instructions below to remove the shipping plates.

Instructions (X-)ASR305B305B
1. Connect the stage to a controller. ASR large user manual 1.jpg
2. Remove the 8 M3 screws securing the shipping plates to the base and mid-plates as shown. ASR large user manual 2.jpg
3. With these screws removed, use the controller to move the upper-axis in order to gain access to the screws on the underside of the top-plate as shown. ASR large user manual 3.jpg
4. Remove the two screws holding the upper-axis shipping plate to the underside of the top plate. Move the upper-axis in the opposite direction in order to access and remove the two screws under the opposite side of the top-plate. Slide the upper-axis shipping plate out and set it aside. ASR large user manual 4.jpg
5. Repeat the same procedure for the lower-axis shipping plate. Move the lower-axis to gain access to the 4 screws holding the lower-axis shipping plate to the underside of the mid-plate. When all 4 screws are removed, remove the plate. The stage is now ready to be installed and used. ASR large user manual 5.jpg

Installation and Removal - (X-)ASR050B050B and (X-)ASR100B120B

On the (X-)ASR050B050B and (X-)ASR100B120B, the inserts are held in place by a spring clip in one corner of the aperture. To install an insert, place the one corner up against the spring first. While holding this corner down, push the insert towards the spring clip and snap the opposing corner into place. Removal is the reverse of this procedure.

For most applications, the spring clip should provide sufficient force to hold the insert in place, while still allowing quick changes between inserts. For applications requiring more secure mounting, custom inserts can be provided that can be secured to the (X-)ASR using 4 M2 screws.

Instructions (X-)ASR100B120B
1. To install an insert, first position the corner next to the spring clip as shown. ASR manual 4.jpg
2. While holding down the corner next to the spring clip, push the opposite corner down. ASR manual 5.jpg

Installation and Removal - (X-)ASR205B205B and (X-)ASR305B305B

On the (X-)ASR205B205B and (X-)ASR305B305B, the inserts are held in place by 3 M4 flat head screws. The screws mate with 3 matching chamfers on the insert to kinematically constrain it. Some inserts also allow for mounting using 16 or 24 M3 screws around the perimeter of the insert. The perimeter screws will secure the insert against high loads, but may compromise the flatness of the stage. It is only recommended that these screws be used when the necessary to prevent the insert from shifting under high loads.

Instructions (X-)ASR305B305B
1. To install an insert, first line up the 3 insert chamfers with the 3 screw pockets in the (X-)ASR top plate. ASR large user manual 6.jpg
2. Screw the 3 M4 x 8 flat head screws into the holes in the top plate as shown. Tighten the screws evenly until the insert is held securely. ASR large user manual 7.jpg
3. If required, the insert can be leveled using the 3 M4 set screws adjacent to the flat head screws. Before adjusting the set screws, loosen the flat head screws. ASR large user manual 8.jpg

Setting Home and Away Sensors

The ASR provides adjustable travel limits for each axis. A home sensor sets the 0 position of each axis and an away sensor determines the maximum travel range.

Limit adjustment is performed by moving the magnets which trigger the sensor. The limit switch magnets are attached to the bottoms of the limit adjustment screws shown in the pictures below.

Tip lightbulb symbol.png Important: If adjusting the magnets outwards, make adjustments in small increments. Exceeding the nominal factory set travel range by more than 3 mm can cause the device to become stuck at one end of travel.

(X-)ASR100B120B
Upper axis limit switch magnets ASR manual 7.jpg
Lower axis limit switch magnets ASR manual 8.jpg

To adjust the limits, loosen the screws by about 1/2 turn, slide the screw to the desired location and re-tighten. Make sure that the green hall sensor PCB (visible through the magnet adjustment slots) always stays in between the limit screws.

When adjusting the limit switch magnets, ensure that the green sensor PCB remains in between two magnets.

Software

In addition to the regular software options available for all Zaber devices, the ASR is supported by Micro-Manager open source microscopy software. Micro-manager can be downloaded for free from the Micro-Manager website.


Trajectory Control and Behaviour

This section describes the behaviour of the axis trajectory when a movement command is issued.

Software Position Limits

The travel range of the axis is limited by the Minimum Position and Maximum Position settings. The factory settings for the axis are configured to match the physical travel range. If a customized range is desired, it can be changed by configuring the limit.min (T:106) and limit.max (T:44) settings to appropriate values. For the Current Position, query pos (T:60).

Minimum Position
When the Current Position is less than the Minimum Position value, the axis cannot move in the negative direction(towards the motor).
Maximum Position
When the Current Position is greater than the Maximum Position value, the axis cannot move in the positive direction(away from the motor).

Movement Speed

The movement speed of the axis depends on axis status and various speed settings. If the axis has not been initialized by the home (T:1) command or by moving towards the home end of the axis, movement speed will be constrained to fail-safe values. The home status of the axis can be determined by reading the limit.home.triggered(T:53:103) setting.

Movement speed of the axis is specified below:

move vel (T:22)
The axis will move at the specified speed regardless of home status.
Knob movement in Velocity Mode
The axis will move at the specified speed regardless of home status.
The speed is specified by the knob.speedprofile (T:112) and knob.maxspeed (T:111) settings.
Other movement commands - when the axis has not been homed
The axis will move at the slower of the maxspeed (T:42) and limit.approach.maxspeed (T:41) settings.
Other movement commands - when the axis has been homed
The axis will move at the speed specified by the maxspeed (T:42) setting.
