Design Changes 10/16/031) Eliminated Tachometer2) Added 2 Encoders (now 3 Gurley’s)3) Eliminated Limit Switches
Results:a) Design Envelope increased 3 inchin height; added one more plateb) Eliminating Limit Switches will re-duce machine shop cost (4 fewer parts+ no speed reducer)
Questions:i) How much room is required on bottomof unit to clear connectors on encoders?
