Chapter 1 - Introduction
Product Description
LP28 Positioner
The LP28 is a linear positioning table of miniature cross section (28mm x 28mm) which provides travel
length up to 500mm. It’s an assembled package including stepper motor, with motor options ranging
from a single stack NEMA 11 to NEMA 17. It employs a PTFE coated leadscrew drive train, with lead
selectable from 1mm to 1”. Linear bearing support is provided by an external square rail bearing.
LD28 Actuator
The LD28 is a linear actuator based upon the LP28, providing nominal travel distance up to 300mm. It
utilizes the same high performance leadscrew as the LP, as well as the same motor options.
Unpacking
Unpacking
Carefully remove the positioner from the shipping container and inspect the unit for any evidence of
shipping damage. Report any damage immediately to your local authorized distributor. Please save
the shipping container for damage inspection or future transportation.
Incorrect handling of the positioner may adversely affect the performance of the unit in its application.
Please observe the following guidelines for handling and mounting of your new positioner.
DO NOT allow the positioner to drop onto the mounting surface. Dropping the positioner can gener-
ate impact loads that may result in flat spots on bearing surfaces or misalignment of drive com-
ponents.
DO NOT drill holes into the positioner. Drilling holes into the positioner can generate particles and
machining forces that may effect the operation of the positioner. Parker will drill holes if neces-
sary; contact your local authorized distributor.
DO NOT subject the unit to impact loads such as hammering, riveting, etc. Impacts loads generated
by hammering or riveting may result in flat spots on bearing surfaces or misalignment of drive
components.
DO NOT lift the positioner by the cables. Lifting positioner by the cables may effect electrical con-
nections. The unit should be lifted by the base structure only.
DO NOT expose positioner to mist, spray or submersion in liquids.
DO NOT disassemble positioner. Unauthorized adjustments may alter the positioner’s specifications
and void the product warranty.

Performance Specifications - LP28
Performance Graph Notes:
To simplify application, the different aspects of positioner performance including motor torque, motor speed, screw efficiency, friction, safety
margin, etc. have been consolidated into these speed versus thrust graphs. To make a selection first use the X axis scale of the different
graphs to identify a screw lead that will deliver the desired peak velocity. Next, using the specific screw lead graph, identify the motor with
enough torque to deliver the needed thrust to lift or accelerate the load.
NEMA 11 Stepper motor curves (M11xx and M13xx options) assume 24VDC bus voltage at 0.67 amps. NEMA 17 stepper motor curves
(M71xx option) assume 48VDC bus voltage at 1.14 amps for series wound operation and 2.28 amps for parallel wound operation. All graphs
are limited to 45N (10lbs) thrust due to mechanical limitations. Care should be taken not to stall the axis into the end of travel, particularly
with the 1mm lead screw (D01 option) as this motor-screw combination can generate significant amounts of thrust. All curves include a 10%
safety margin.
The “Maximum Recommended Speed” is based on a maximum motor speed of 15 rps. Generally, the motors can rotate faster than 15 rps;
however, at about 20 rps, they pass through a resonance which adversely and unpredictably affects useable motor torque. For applications
requiring higher speeds, Parker recommends using a faster lead or a servo motor. Applications using a stepper motor above this recom-
mended limit must be fully tested and qualified by the user.

The limit/home switch installed on the LP28 is a
hall effect sensor tripped by a magnet embed-
ded in the carriage. On the switch body is an
LED to indicate activation, visible through the
clear polycarbonate mounting clip. Normally
open (N.O.), normally closed (N.C.), current
sinking (NPN) and current sourcing (PNP)
variations are selectable with the product. Nor-
mally open sensors are typically used for home
and normally closed are typically used for limits. With a current sinking sensor, the output lead provides a path to ground when acti-
vated, and with a current sourcing sensor, the output lead provides a positive (+) voltage potential relative to ground. Refer to you con-
troller’s manual for compatibility. Limit/home switch information is below. See Appendix A for switch part numbers.

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.
Chapter 4 - Setup and Usage
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.
Normal Side Vertical Inverted
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.

Payload Mounting - LP28
Payload is mounted to the LP28 using M3x0.5 tapped holes in the load plate. Six holes exist in the top of the
load plate and four exist in the side. When fastening to the load plate, take precaution in using screws with
no more than 5.5mm of engagement, as to not damage the positioner. See Chapter 2 for hole location. The
hole patterns are designed to build X-Y and X-Z configurations using only accessory toe clamps. If doing so,
be certain not exceed the moment load specifications outlined in Chapter 2.
Use Appropriate Length Bolt
The LP28 design requires proper size bolts to be used when mounting payloads to the load plate.
Excessive length bolts can cause damage or pin the table in position.
Leadscrew Nut Attachment - LD28
The LD28 leadscrew nut is attached to its mating component using a 7/16-20 male thread on the nut. See
Chapter 2 for dimensional specifics. If the leadscrew nut needs to be removed from the leadscrew in order to
install the actuator, preload will need to be reset. See Chapter 5 for procedure.
The LD 28 has approximately 8mm total overtravel (travel distance in addition to nominal travel) that must be
taken into consideration when installing the actuator. The overtravel is in place so the leadscrew nut is not
required to move over the extreme ends of the screw during use. At the fixed end there may be ≤2mm of
length that contains traces of adhesive, and at the free end there will be a chamfer ≤2mm long on the end of
the screw, rendering these areas undesirable for travel of the nut. Further, extreme care should be taken not
to travel the leadscrew nut so that it makes contact at the fixed end, because this will change preload setting
and possibly cause damage.
