Number Component Description
1 Ground Screw and Ground Label Use the labeled M5 x 0.8 - 6H ground screw to connect to the linear stage to a facility safety ground.
2 Bearing Lubrication Ports These capped ports provide access to the linear bearings without dismantling the stage. In addition these tapped holes
(M10 x 15. -6H) can be used to secure lifting hooks (not provided)
3 Stage Slide Your application hardware mounts to this slide by using provide mounting holes.
4 Stage Cover If the strip seals are used this protective cover the stage has magnetic edges to keep the upper edge of the strip seals in
place.
5 Seal Guide These guides lets the strip seal to move smoothly around the stage slide.
6 Cable Carrier Module Facilitates quick and easy replacement. Replace the cable carrier module every 10 million cycles.
7 Stage Side Cover If the strip seals are used this protective cover the stage has magnetic edges to keep the lower edge of the strip seals in
place.
8 Side Cover Support These supports are used on long stages to stabilize the side cover.
9 Stainless Steel Strip Seal These replaceable, flexible stainless steel strips permit the stage to move while isolating the internal mechanism of the
stage from environmental contaminants.
10 Strip Seal Clamps These clamps hold the strip seal in place. When replacing the strip seals, they are used to position it so it lays smooth against
the top and side stage covers.
11 Index Mark Part of the encoder system that provides a home location for the encoder.
12 Optical Encoder Readhead This encoder readhead comes in various resolutions and requires little maintenance.
The TTL encoder option provides quadrature incremental position feedback with a differential signal on a RS-422.
The Sine/Cosine encoder option provides a 1 volt peak-to-peak sine and cosine output at a period of 20 μm. The Sine/Cosine
encoder is also known as an analog encoder.
13 Encoder Scale Part of the encoder system that provides an optical pattern to be read by the encoder readhead. It must be kept free of
contamination for proper operation.
14 Bearing These support bearings guide the slide on the bearing rail, they require periodic lubrication.
15 Motor Coil This coil is part of the two piece linear motor. When excited by a linear drive, it generates magnetic forces that interact with
the magnet track creating motion. LC linear motor option shown. LZ linear motors have a different configuration.
16 Bearing Rail These rails provide the linear track that the slide assembly rides on, they must be kept free of debris.
17 Magnet Track This track of powerful static magnets is the other half of a linear motor. LC linear motor option shown. LZ linear motor option
has a magnet channel.
18 Limit Blade Provides a mechanical trigger to the limit sensor.
19 Limit Sensor These optional sensors output a signal when the limit blade passes in front of them. The position of these sensors can be
adjusted to suit your application, see
Operation Guidelines and Limit Configuration section on page 49 .
20 Hall Sensor Module Three Hall sensors in this module are provide for commutation startup and phase alignment. They can also be use for
trapezoidal commutation of the motor.
21 Bumper Stop These springs absorb slide and payload energy in the event the stage loses control. See page 53 for absorption limits.
