Mounting Considerations
The HEDS-5540 and 5640 three
channel encoders and the HEDM
Series high resolution encoders
must be aligned using the aligning
pins as specified in Figure 3, or
using the HEDS-8910 Alignment
Tool as shown in Encoder
Mounting and Assembly.
The use of aligning pins or
alignment tool is recommended
but not required to mount the
HEDS-5500 and 5600. If these
two channel encoders are
attached to a motor with the screw
sizes and mounting tolerances
specified in the mechanical
characteristics section without
any additional mounting bosses,
the encoder output errors will be
within the maximums specified in
the encoding characteristics
section.
The HEDS-5500 and 5540 can be
mounted to a motor using either
the two screw or three screw

mounting option as shown in
Figure 2. The optional aligning
pins shown in Figure 3 can be
used with either mounting option.
The HEDS-5600, 5640, and
HEDM-5600 have external
mounting ears which may be used
for mounting to larger motor base
plates. Figure 4 shows the
necessary mounting holes with
optional aligning pins and motor
boss.
