Encoder Maintenance
RSF Series MSA6x Enclosed Type
Technical Data: Linear encoders measure the position of linear axis without mechanical
translation components. This reduces the potential error due to thermal behavior of the
linear motor and backlash from mechanical translation.
Encoder type: Non contact optical, sealed type. Sealed linear encoders are used in
harsh environments in such applications as milling machines, drilling machines, grinding
machines, lathes, electrical discharge machines, and welding machines.
Mechanical design: Glass scale, optical scanning unit, high flex twisted shielded cable.
Encoder scale, optical scanning unit and guide–way are protected from chips, swarf, dirt
and fluids by an aluminum housing and flexible rubber type seals. The optical scanning
unit travels on a low friction guide within the encoder enclosure.
Maintenance: The exterior of the encoder should be inspected and cleaned. An alcohol
or soapy water saturated cloth is usually effective for removing external contamination. If
the internal components are contaminated, please consult with Baldor or an authorized
distributor for assistance. (DO NOT attempt to dissemble the encoder enclosure).

Reference mark: ±one count (bidirectional)
(reference marks located 35mm from each end)**
* Scaling is a calibration technique used to determine and communicate linear encoder
and positioning stage mechanical characteristics, (accuracy and resolution) to the
motion controller.
** Custom location reference marks can be ordered, contact Baldor for more information
Note: Max speed is determined by the encoder resolution, the controller’s band
width and the mechanical limitations of the positioning stage. Should you
need assistance in calculating the maximum speed for the positioning stage,
please consult with Baldor.
