Introduction

This manual describes the operation of Siskiyou’s 840 Series Linear Actuators, 100cri, 200cri, 7000, and 830 Series Stages, RSA-i Series motorized rotational stages, MXMS-cri Series Microscope Stages, MX7000 Series Micromanipulators, and MX831 Micromanipulators, as well as their related controllers.

MXMS-cri Series Microscope Stages, MX7000 Series Micromanipulators, and MX831 Micromanipulators are made up of 7000 Series Stages, and 830 Series Stages. Therefore the descriptions and operating features of the respec-tive stages correspond to the related microscope stage, and micromanipulator systems as well.

Inspection
Siskiyou products are shipped in sturdy, cushioned boxes. Please inspect the instrument and/or controllers immediately and notify the carrier if damage is obvious.

Description
Siskiyou’s 840 Series Actuators, 100cri, 200cri, 7000, and 830 Series Stages, MXMS-cri Series Microscope Stages, MX7000 Series Micromanipulators, and MX831 Series Micromanipulators incorporate mechanical limit switches that cut motor power preventing accidental over-travel.
The 840 Series Actuators can be configured with travel limits from approxi- mately 1/32 inch to 2 inches (0.8 mm to 50 mm), enabling them to be used on a wide variety of Siskiyou translation stages.
To provide accurate motion, the 840 Series Actuator’s 3/16-inch diameter plunger is non-rotating. A non-rotating low friction composite nut engages the leadscrew and pushes the actuator plunger or stage platform. In the 840 Series Actuators a composite half-nut is used to trigger a travel limit in the extended position while the lead screw nut trips the limit at full retraction.

* Caution
If an actuator or stage encounters a hard stop within its range of travel (a translation stage’s or mirror mount’s end of travel, for example), STOP THE DEVICE AS SOON AS POSSIBLE! CONTINUED OPERATION WILL DAMAGE THE INSTRUMENT!
These actuators and stages are powered by low inertia DC servomotors to provide smooth movement with low acoustic and mechanical noise. Submicron resolution is obtained with a precision stainless steel leadscrew driven through an anti-backlash reduction gearbox.
The motor has an ironless-rotor to permit fast response due to its low inertia. The brushes are precious-metal plated for long life. The factory lubrication has a vapor pressure of 10-6 Torr at 25°C.

Controller Interfaces
The 840 Series actuators, 7000 Series and 830 Series stages incorporate travel limit switches. Additionally, since these instruments use high torque motors and anti-backlash gearboxes, their comparability with non-Siskiyou controllers may be limited. The following sub-sections describe the comparability and features of Siskiyou controllers.

MC1000e-R1 Single-Axis Dial
The MC1000e-R1 uses encoder feedback from our closed loop devices to cre-ate an electronic link between the controller dial and the device being driven. This direct coupling to the encoder ensures smooth and coordinated motion between the controller and the drive. The encoder coupling enables the use of the DR1000 digital readout for repeated positioning requirements.

A two-position rocker switch is located on the top of the controller. The rapid setting is set to maximize speed (1.7 mm/second) when the dial is turned at 180 RPM. The slow setting is set to maximize resolution (0.2 µm) but still allow coarse positioning (45 µm/second).

MC1000e-R/T 4-Axis Closed Loop Dial TARGET/RETRACT
The MC1000e-R/T 4-axis dial controller acts as a remote micrometer control with a user selected target feature for 800 and 7000 series actuators, manipu- lators, and stages. The MC1000e-R/T 4-axis dial controller acts as a remote micrometer control with a user selected target feature for 800 and 7000 series actuators, manipulators, and stages. The MC1000e-R/T uses encoder feed-back from our closed loop devices to create an electronic link between the controller dial and the device being driven. This direct coupling to the encoder ensures smooth and coordinated motion between the controller and the drive. The encoder coupling enables the use of the DR1000 digital readout for repeat-ed positioning requirements.
A two-position rocker switch is conveniently located on the side of the con- troller. The rapid setting is set to maximize speed (1.7 mm/second) when the dial is turned at 180 RPM. The slow setting is set to maximize resolution (0.2 µm) but still allow coarse positioning (800 µm/second).

The TARGET/RETRACT allows the user to set a target location at a desired point. When it becomes necessary to back away from the experiment area, the user simply depresses the RETRACT button on the controller. The stage/actua- tor plugged into that axis (No.1), then automatically retracts to its full negative limit. The user can then return to the previously set position by simply depress-ing the TARGET button. The MC1000e-R/T uses a wall mounted power supply as its source for clean DC power. All cables are shielded and a central ground lug is located on the junction box to ensure noise-free operation during sensitive electrophysiology experiments.

MC1000e-J 3-Axis Joystick
Siskiyou’s MC1000e-J 3-axis joy-stick controller is compatible with all of our 840 Series Actuators, 7000 Series Stages, 830 Series Stages, 7000 Series Micromanipulators, and 831 Series Micromanipulators. The MC1000e-J controller is a closed loop controller that enables the user to consistently perform smooth joy-stick motion as small as 1 µm.

A two-position rocker switch is located on the top of the controller. The rapid setting is set to maximize speed (1.7 mm/second) when the joystick is moved to its farthest position from center. The slow setting is set to maximize resolution (0.2 µm) but still allow coarse positioning (20 µm/second).
Reverse polarity switches are included for each motion direction of the MC1000e-J. By switching the polarity, the direction of motion relative to the joystick is reversed.

MC1100e 4-Axis Targeting
Siskiyou’s MC1100e hand held 4-axis controller is compatible with all of our 840 Series Actuators, 7000 Series Stages, 830 Series Stages, 7000 Series Micromanipulators, and 831 Series Micromanipulators. The MC1100e Controller is a closed loop controller that enables the user to consistently perform single step moves as small as 0.2 µm. The MC1100e incorporates a “Targeting” feature for one axis. This feature enables the user to pre-set a target point on that axis, “Retract” to the negative limit of travel and return to that pre-set point simply by depressing the “Target” button on the controller.

The targeting axis is axis number 1. To set a point of reference when axis 1 is in a desired position, push the “Target Set” button. To retract the motorized axis 1, push the “Retract” button. Once this axis has reached its reverse limit switch the red LED will light up. To bring the axis back to the target position, push the “Target” button. When the green LED lights up, the motorizer is in the target position. For best results and to avoid backlash, the direction of travel when the “Target Set” button is pushed should be a forward move; that is, the same travel direction as the movement from the limit switch to the target.

* Note: For all axes to operate, the targeting axis 1 must be connected.

Motorized XYZ Stages
The 7000 series motorized crossed roller bearing translation stages are an integrated version of our 1600 series crossed roller translation stage. They use a precision pre-loaded lead screw to ensure drift-free operation.

Our e series and MC2000 Series controllers drive the stage through a closed loop interface between the controller and the motor encoder. The closed loop connection ensures 0.2 µm and 0.1 µm resolution, respectively. The encoder coupling also enables the use of the DR1000 digital readout for repeated or relative positioning requirements.

7000 series stages come standard with our ABP-R mounting plate. The design of this mounting plate enables coarse positioning between platform mounting holes as well as 360° of coarse rotational positioning. If rotation with a solid submicron level stop is required, the MX-RS rotation stage is designed to mount directly into the ABP-R and has mounting holes for all 1600 series stages.

• No maintenance is required under normal operating conditions.

The MX7600 uses a precision pre-loaded lead screw to ensure drift-free operation and has applications in patch recording experiments. The motorized 4-axis micromanipulator incorporates our MXC-45 pipette holder mounted to an adjustable clamp on the Ø axis. This clamp allows the MXC-45 and Ø axis to be adjusted to the desired angle of approach from 0° to 180° for true axial approach. The MXC-45’s built in rotational stop allows easy pipette replacement.

The MX7600 can be used with our e series and MC2000 Series controllers to drive the 7600 stage through a closed loop interface between the control-ler and the motor encoder. The closed loop connection ensures 0.2 µm and 0.1 µm resolution, respectively.

Model 840 Series Actuator
The 840 Series Actuators can be configured with travel limits from approximately 1/32 inch to 2 inches (0.8 mm to 50 mm), enabling them to be used on a wide variety of Siskiyou translation stages.
To provide accurate motion, the 840 Series Actuator’s 3/16-inch diameter plunger is non-rotating. The standard gearbox ratio actuator can produce a maximum thrust in excess of 25 pounds (11 kg); but, when operating continuously over many cycles, the maximum load is rated at 18 pounds (8 kg). A non-rotating low friction composite nut engages the leadscrew and pushes the actuator plunger or stage platform. In the 840 Series Actuators a composite half-nut is used to trigger a travel limit in the extended position while the lead screw nut trips the limit at full retraction. The limit switches are repeatable to approximately 40 µm.

Installation, Setup, and Operation

Setting the Travel Limits
(840 Series Actuators only)
Before mounting the 840 Series Actuator, follow the directions below to adjust the travel limits such that the actuator will trigger one of its limit switches before encountering any external hard stop such as the end of travel of a translation stage. Failure to do this may result in damage to the actuator and/or the stage. Actuators are shipped with the travel limit set to less than 1/2 inch (12mm) to prevent accidental over-travel in most instances.

Remove the Coarse Travel Indicator Window
Find a clean, flat surface to disassemble the actuator. (Tapped hole optical tables are not recommended since many of the parts are small and may drop into the table.) Using your controller, adjust the actuator to the zero position as read on the coarse position scale as shown in Figure 1. Remove the four #2-56 flat head screws holding the indicator window lid, place them to the side and gently lift off the lid, Figure 2.

Figure 2
Approximate travel range markings assist in quick travel adjustment.

Reposition the Half-Nut to the Desired Travel
After removing the lid, laser marked lines indicating approximate travel ranges can be seen. Remove the half-nut by lifting it from the leadscrew. Note its orientation with respect to the leadscrew since it only fits one way (Figure 3). Approximate travel is set by replacing the half-nut onto the leadscrew with its center scribe mark aligned to one of the markings on the actuator body (Figure 4). These marks are only an aid to determining travel. The half nut may be placed anywhere along the lead screw. For full 840 Series Actuator travel, remove the half nut completely and store it in a safe place for future use in case shorter travel is desired.

Replace the Coarse Travel Indicator Window
After inspecting the half-nut placement to ensure that it is fully seated on the lead screw, replace the lid and tighten the four #2-56 screws. Be sure to tighten the screws completely for proper operation (Figures 5 & 6). If the lid is loose, the half nut may ride up off the lead screw at the end of travel and defeat the purpose of the limit switch resulting possibly in damage to the actuator or the equipment it is moving.

Actuator mounting
The 840 Series Actuators may be mounted using either the 3/8 inch brass nose mount or by attachment using the clearance holes in the actuator body. When using the brass mounting sleeve, the actuator may be mounted to a wide variety of Siskiyou’s components in one of four ways:

1. Unscrew the 9/16″ retaining locknut and insert the 840 Series Actuator into the mount. Either use a wrench to tighten the nut, or if space permits, gently rotate the actuator body while holding the nut stationary with the fingers or a small screwdriver to tighten the whole assembly.
2. When the mount has a set screw, the retaining nut is not used. Insert the actuator and tighten the set screw.
3. In rare cases, when neither of the above two mounting methods can be used, it might be necessary to partially disassemble the device in which the actuator is being used. When access to the retaining nut side is reached, follow method #1 above.
4. For panel mounting in panels up to 1/2″ thick, drill a 3/8″ hole. Insert actuator and tighten retaining nut.

Stage mounting
The 7000 Series and 831 Series Stages have specific mounting procedures for the two styles of stage.
To mount the 7000 Series Stages, loosen the 1/4-20 pivoting base locking screw located in the side of the supplied ABP-R mounting base. Once loosened, slide the stage and the mounting base apart. Next, mount the ABP-R mounting base in the desired location with the two 1/4-20 thumb screws that are supplied. Once mounting base is in the desired position, slide the stage back into place and lock with the 1/4-20 pivoting base locking screw. The 7000 Series Stages may also be mounted using any of the 8-32 or 4-40 holes in the base or side of the stage.

* Note: Care should be taken to not over tighten or use screws which are too long when using these mounting points.

Vacuum compatible versions
840 Series Actuators, 7000 Series, and 831 Series Stages can be ordered to operate cleanly within a vacuum environment as high as 10-6 Torr. The following describes the alterations that make the standard actuators vacuum compatible;

1. Six foot Teflon-coated cable from actuator/stage attached to six foot standard cable.
2. Uncanonized aluminum body without label.
3. No fastener sealing compound.
4. The window material is removed.
5. Special lubricant with vapor pressure of 10-6 Torr at 39°C.
6. All blind holes and cavities are vented.

Motorized Rotational Stages
All rotational stages use ball bearings for smooth motion and solid support.

RSA-0.5i
The compact size and high performance of our RSA-0.5i motorized rotation stage make it ideal for motorized rotation applications in the laboratory as well as OEM systems. By employing our standard encoded DC servo motor, the overall thickness of the base is minimized to 1.0-inch [25-mm].
Standard mounting features include both 1⁄4-20 and M6 tapped holes on two edges for post or AS spacer mounting with the axis of rotation horizontal. Additionally, universal counterbores (U.S. system and metric spread) are included for attachment directly to a isolation table or platform with the axis of rotation vertical. The 0.5-inch inner diameter of the rotating dial accepts com-mon 0.5-inch and 12-mm optics and is supplied with two Delrin® retaining rings. The dial has six tapped holes (3 each 4-40 and M2.5) on the face to attach other optical or mechanical elements.

The RSA-0.5i’s compact design and right angle drive are ideal for close coupled optic stacking.

The compact size and high performance of our RSA-2.0i motorized rotation stage make it ideal for motorized rotation applications in the laboratory as well as OEM systems. By employing our standard DC servo motor, the overall thick-ness of the base is minimized to 1.0-inch [25-mm].

Standard mounting features include both 1⁄4-20 and M6 tapped holes on two edges for post or AS spacer mounting with the axis of rotation horizontal. Additionally, universal slots (U.S. system and metric spread) are included for attachment directly to a isolation table or platform with the axis of rotation verti-cal. The 2.0-inch inner diameter of the rotating dial accepts common 2.0-inch and 50-mm optics and is supplied with two Delrin® retaining rings. The dial has twelve tapped holes (6 each 8-32 and M4) on the face to attach other optical or mechanical elements.
