# sample file pulls all load commands into a single file
# when emc2 starts it loads iocontrol
# this file enables encoder velocity timestamping
# it will only work on PPMC encoder boards with
# rev 4 or later firmware.  In addition to the timestamp
# feature, rev 4 and above boards also have the ability to
# select the encoder digital filter frequeincy.  Append
# enc_clock="n" to the loadrt hal_ppmc line.  N can be
# 1, 2, 5 or 10 for 1, 2 5 or 10 MHz frequency.  Any other
# value will default to the standard 1 MHz.
# it is best to use the lowest rate that allows your encoders
# to be read, as this gives the greatest suppression of
# electrical noise on the encoder inputs.
