4.6.8. CONFIGENCODER (encoder_ch) (lines_per_revolution)
(bounded)
The CONFIGENCODER command allows the user to assign an encoder feedback
channel to an axis to be used as the position and/or velocity feedback for that axis. The
valid range of encoder feedback channels is determined by the number of encoder
feedback channels present in the user system. The lines per revolution parameter indicates
the number of lines per revolution of the encoder times 4. The UNIDEX 600 Series
controller electronically multiplies the effective line count of the encoder by 4, so the
lines per revolution entered should always be four times the physical line count of the
encoder. The bounded parameter is used to activate software end of travel limits by
entering a 1 for this parameter (0 to disable them).
A UNIDEX 600/650 controller has 4 channels onboard with 4 additional channels
provided by each additional encoder expansion card. Their channel numbers are
determined by the expansion board number. Expansion board number one will be
channels 5 through 8, board two will be channels 9 through 12, etc.
Attempting to configure an axis for an encoder channel that is not present will cause a
programming error. This error will be indicated by the GETPROG command after the bad
configuration attempt.
