15. Select the Parameter List category. Enter the necessary changes

based on your application requirements.

NOTE: Velocity Filter Bandwidth, Acceleration Filter Bandwidth, Velocity

Threshold and Velocity Standstill Window cannot be set from the

Parameter List. To set these parameters, use the following message

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
