The LD28 actuator can be mounted in a horizontal or vertical orientation. For vertical mounting, care must be
taken since certain leadscrew and load combinations can backdrive in a power loss situation. If possible, in
the vertical orientation it is preferred that the positioner be mounted such that the motor is at the top.
The LD28 actuator can be mounted by the following three methods:
•
Toe Clamps - Installation is similar to the LP28. Four toe clamps
are recommended for mounting the LD28.
•
Face Mount - Four M2.5x0.45 tapped holes exist in the face of the
base profile for mounting. See Chapter 2 for location.
•
T-Slots - Two T-slots exist in the sides of base profile that can be
employed for mounting. M2 square nuts are intended for use in the
T-slots. See Chapter 2 for slot location and Appendix A for square
nut drawing and part number.

Mounting - LP28
The LP28 positioner can be mounted in a normal, side, vertical, or inverted orientation. For vertical (Z axis)
mounting, care must be taken since certain leadscrew and load combinations can backdrive in a power loss
situation. If possible, in the vertical orientation it is preferred that the positioner be mounted such that the mo-
tor is at the top. For all orientations, the cables should be secured as to not interfere with the movement of
the carriage and load plate.

The LP28 positioner is mounted via accessory toe clamps that engage the bottom
slot in the base profile and are intended for use with an M3 screw. The clamps are
a cam style that can be loosely installed without the positioner in place, then ro-
tated into the slot and tightened. Minimum toe clamp spacing along the length of
the base profile is 150mm. With shorter units, a minimum of four clamps are rec-
ommended. See Chapter 2 for toe clamp location, and Appendix A for toe clamp
drawing and part number.
