Connecting
Provide slack
loops
Secure excess
cable
Attach connector
•Route the cables with slack loops to allow for axis motion.
•Secure excess cable by fastening with clips or ties.
•Attach the linear encoder connectors to the readout.
Counting Test
Readout
•Move the axis and compare the display to the movement.
•Move the axis 20mm (.79”) to check reference mark operation.
These steps will confirm proper operation of your installation. The Counting Test confirms proper electrical operation. The Repeatability Test checks the installation integrity.
CountingTest:
•Configure the readout’s encoder and display resolution (see manual).
•Move the axis and compare the display to the movement.
•Configure readout for sensing reference marks.
•Move each axis a minimum of 20mm (axis display should zero).
RepeatabilityTest:
•Locate an indicator on one end of the encoder and zero the readout and indicator.
•Move the axis through the full travel and return to dial zero.
•Readout should read zero ± 1 count.
Repeatability Test
Place dial indicator at the end of the moving component (scale assembly or reading head).
•Zero the display and indicator.
•Move axis to the end of it’s travel return to dial zero.
•Readout should read zero ± 1 count.
