instructions.
This procedure sends a Logix message to set the following parameters.
a.
Velocity Threshold: This parameter defines a minimum
absolute velocity. If the magnitude of the velocity feedback
signal is less than this value, the Velocity Threshold status bit is
set.
IMPORTANT These new values are set to volatile memory and are not retained upon a
power cycle. Follow the sample below or use a similar method to write the
values to the encoder memory after a loss of connection to the device.
