Run Up/Coast Down Application
The Enpac 2500 Run Up/Coast Down application allows the Enpac 2500 to
record and analyze data from intermittent events and transient vibration signals
from non steady state machines.
The Run Up/Coast Down application is an add-on program to the Enpac 2500
and must be installed with the Run Up/Coast Down SD or PCMCIA card from
Rockwell Automation.
Refer to Adding Applications to the Enpac 2500 Data Collector on page 59 for
installation instruction.
Overview of the Run Up/
Coast Down Application The Run Up/Coast Down application is used to record and analyze data from
machines where noise or vibration levels are changing with speed or time such as
during a run up (increase in speed), coast down (decrease in speed), or other
applications causing transient phenomena. One of the primary objectives of this
application is to establish the critical or resonant speeds of a machine.
