Warning exclamation.png Mounting and Maintenance Hazard! For operator safety, the {{{Device}}} should always be un-powered during all cleaning, maintenance, and stage or load mounting operations. A powered stage could exert high forces and move at high speeds very suddenly if accidentally given a move command.

Shipping Safety

Upon receipt of the stage, remove the two straps securing the stage top before attempting to power-up the stage. If transporting or shipping the stage, it is recommended that replacement straps be installed to prevent the carriage from moving during shipping.

Important Precautions for Use

Warning exclamation.pngStrong magnet.jpg Strong Magnets! The {{{Device}}} stages contain strong magnets that could affect pacemaker function. Pacemaker users should stay at least 20 cm away from the stages. The magnets can also attract nearby magnetic objects. Use caution when mounting the device as fasteners and tools can easily be pulled into the magnet track. Use non-magnetic fasteners and tools whenever possible.

Warning exclamation.png Secure Stage Mounting Required! The {{{Device}}} stages are heavy and can shake and vibrate during operation due to high inertia. The stages must always be securely mounted to a work surface during operation. See #Physical_Installation for information on stage mounting.

Tip lightbulb symbol.png Important: The {{{Device}}} stage should be homed immediately upon power-up. Behavior may appear jerky during homing. Once the stage has been homed, motion will be controlled and smooth.

Warning exclamation.png Back-driving Hazard! Linear motor stages require current to the motor coils to provide a force to maintain position and/or support a load. If power is removed the carriage may move suddenly or in an uncontrolled manner. The {{{Device}}} stage is not intended for load lifting operations due to the risk of uncontrolled motion if driver power is removed.

Tip lightbulb symbol.png Important: The {{{Device}}} is a servo device, meaning that its performance is dependent on proper tuning of the servo parameters for the given load. The use of incorrect servo parameters may reduce the device’s performance in operation. Incorrect tuning may also result in unstable operation, which can cause unexpected rapid motion of the device, leading to reduced device lifetime and user injury. When the operating load on the device is changed, the tuning parameters should be updated to match. For details see the servo tuning guidelines.

Lubrication of Linear Guides

The {{{Device}}} series of linear stages use recirculating ball bearing linear guides to support and guide the stage top of the device. These linear guides require lubrication in order to achieve the longest possible lifetime at the highest possible performance. At the rated load of the device, it is recommended to re-lubricate each bearing block on the linear guide at a 500 km service interval. We recommend using 0.2 cm³ per bearing block of a NLGI Grade 2, lithium soap based grease. All guides come pre-lubricated and are ready to go out of the box.

Encoder Care and Cleaning

The {{{Device}}} uses a high precision, optical linear encoder for position feedback. The read head is mounted out of harm's way under the stage top, but the tape scale is mounted to the side of the motor (shown below) and can be damaged if care is not used when mounting the device. Avoid contacting the tape scale with tools and fasteners. Should the device be used in a dusty environment and debris is deposited on the tape scale, the encoder signal strength may be compromised and cleaning will be required. Using a dry, lint free wipe, gently wipe the scale along the travel of the device to clean the scale.

Cable Chain Care

The {{{Device}}} uses a polymer cable chain to protect and guide the cable assemblies for the motor and encoder. It is a robust guide but care must be taken to ensure its functionality and longevity. Do not grab the chain with the intent to move, reposition, or lift the stage. Ensure that during operation, the chain is allowed to move freely without it sliding on or impacting a stationary surface

Noise Emissions

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