Step 4b:
To adjust limits to reduce travel: With a razor, cut the clear
protective sticker at the end of the magnet that is to be adjusted.
Flatten out protective sticker at the cut, this allows a flat surface to
adhere additional magnet. Place additional self adhesive magnet
(supplied with positioner) at the end of the existing magnet which
equals the amount of desired travel reduction. Confirm that there is
no gap between the original magnet and the additional magnet just
applied. If there is a gap, remove the additional magnet, discard it,
and apply a new magnet.

Step 5:
Gently slide bracket under carriage. Push up on bracket, insert 0.5mm to 1.0mm shims
between bracket and base, insert and tighten BHCS.
Setting Home Sensor
The MX80L is equipped with a “home” position reference sensor when purchased with Home
configuration option [H2] or [H3]. The home sensor is located on the same PCB as the limit sensors and
the target is located between the limit targets. The sensor is typically used in conjunction with the
encoder ‘Z’ marker. If another home location is desired, the home target can be adjusted by removing
the limit flag decal and applying adjustment overlay decals in the desired location.

Z Channel Position Reference
The Z channel is an output on the encoder. Many servo controllers support this input. The Z channel on
the MX80L is at mid travel. The Z channel is a unidirectional device. This means that the final homing
direction must occur in one direction. The MX80L is set that the final home direction is to be toward the
positive end of the table (See Chapter 2, Dimensional Drawing, for positive direction definition). The
repeatability of the Z channel is equal to the repeatability of the table. Thus the repeatability of the “Z”
channel equals:

NOTE: Home repeatability is also very dependent on controller input speed and homing algorithms. The
above repeatability does not include possible controller tolerance. Additionally, to achieve the highest
