Introduction
 is product set consists of the PL101-R/PL101-RH head unit and
the MJ832 interpolator, which supports the Mitsubishi Electric
Corporation serial protocol.  is set is used in combination with
the SL700/SL710 scale (sold separately).

Usage Notes
• Do not place objects that generate strong magnetic  elds in the
vicinity of this product.  is could harm the accuracy of the
scale.
•  is product should be used within an ambient temperature
range of 0 to +45 °C, and should not be exposed to direct sunlight
or heat sources.
• During operation, be sure to keep the unit 0.5 m or more away
from large power relays, high voltage or large current switches,
or other sources of noise.
• Wire the head cable and output cable separately from power
lines.
• When coupling relays, solenoids, motors or other devices to this
unit, be sure to take measures to prevent noise.
• Although the connection cable (for extension, sold separately)
has been designed with su cient durability for normal operating
conditions, be careful not to apply excessive stress to the cable.
 is could severely harm the durability of the cable.
• Make sure that the external magnetic  eld does not exceed
0.5 mT.
Head unit
Head Unit Installation Procedure
Preparation
• First, install the scale. For the installation procedure, refer to the
instruction manual for the scale.
• Check the range and surface accuracy of the installation
surface.
• Check the accuracy of the mounting screw coordinates.
•  e M3 tap screws mounted on the case have a depth of 5 mm.
Obtain screws with a suitable length according to the thickness
of the mounting brackets.  e  tting length of the screws should
be 4 to 5 mm.
Installation
1. Align the unit Magnescale marks on the scale and head unit so
that they are facing the same direction.
2.  e head unit is inscribed with a center mark that serves as a
guide to the signal detection position.
Install so that the center mark is always within the e ective
length.
3. Set the origin so that the center mark matches up with the
center of the reference point mark on the scale.

4. Insert the supplied spacer between the head unit detection
surface and the scale, and then mount the head unit and secure
in place using M3 screws.
 e tightening torque should be 0.6 to 0.8 Nm.
5. A er mounting the head unit, remove the spacer.
6. Check the relative positions of the scale and head unit. (See the
 gure below.)

Interpolator
 e MJ832 interpolator is an incremental serial bidirectional signal
(compliant with EIA-485) interpolator that supports the Mitsubishi
Electric Corporation serial protocol. For information on supported
Mitsubishi Electric Corporation servo ampli ers, contact your
Magnescale Co., Ltd. sales representative.
Notes
•  is interpolator does not support multi point and reference
mark.
• Connect a ground wire to the surface on which the interpolator
will be installed. Failure to make a ground connection may result
in worsened noise resistance.
Count Direction
When the head unit and scale are installed as shown below, head
unit movement to the right is the subtraction direction, and to the
le is the addition direction.
