Specifications

For over 40 years, our engineers have been designing encoders that are quick and easy to
install. With a variety of mounting options available, your encoder should be a perfect match
for your existing equipment. Accessories such as pivoting mounting brackets, measuring
wheels, flexible couplings, etc., are available from EPC to ease installation.
The first principle for every encoder installation is "Don't force it!". Striking or using
excessive force can either damage your new encoder, or introduce excessive shaft loading,
shaft misalignment, or other conditions shortening its expected life. Tighten all couplings and
bolts to their recommended torque. Remember, tighter isn't always better!
• Gently couple the shaft of the Accu-Coder
TM
to the driving
shaft, using a correctly sized flexible shaft coupling.
Never use a rigid coupling.
• Verify proper alignment between the Accu-Coder
TM
shaft
and the driving shaft.
• If using pulleys or gears, mount them on the shaft as close
as possible to the Accu-Coder
TM
to reduce bearing load.
• Axial and radial shaft loading should be low as possible.
Never exceed printed specifications.
• Use recommended torques to tighten all clamping bolts and
couplings.
• Make sure driving shaft is free from burrs and other defects.
• With flex mount flush against surface, tighten clamp or set
screws first, then bolt flex mount to surface.
• Check for best possible alignment with hollow shaft and
driving shaft to reduce wobble.
• Runout of the driving shaft, or misalignment between the
driving shaft and the encoder’s hollow bore, decreases the
accuracy and bearing life of the encoder and adds vibration
to the system. Re-installing the encoder on the driving shaft
may improve alignment.
• Verify that mounting holes are in exact alignment with holes
or studs on the motor frame.
• Tighten all fasteners with equal torque so as not to distort the
shape of the ring.
