Rockwell Automation WebPak CS Software Version 1.0 - Manual (Page 11)

Introduction 1-3
1.5 Safety Information
The WebPakCS software operates as a Windows 95 application. It cannot preempt
other applications or functions in Windows and, therefore, cannot guarantee a
response time to user input actions. Using other applications while controlling a drive
with the WebPakCS software can tie up PC resources and cause drive commands to
be delayed.
To prevent drive commands (run, stop, and jog) from unexpectedly executing, the
WebPakCS software specifies a time-out period (approximately 2 seconds) when it
establishes a link with the drive. While the link is established, the WebPakCS software
sends messages to the drive to validate the link. If a message fails to reach the drive
within the time-out period because program execution has been delayed, the drive
invalidates the link. If the link becomes invalid, the drive does not accept drive
commands. If the drive was running, it stops, and a serial fault is generated.
Before a drive control command is sent to the drive, the drive’s status is checked to
validate the link. If communication between the WebPakCS software and the drive
have been interrupted and you have selected a drive command, the command is not
sent and a message is displayed.
The time-out period is also used by the Parameter Monitor and Download functions,
both of which could be running while the Drive Control Window is open. If the link
becomes invalid while these functions are running, a message will be displayed in the
Drive Control window before the link is re-established. When you select the Download
command while the Drive Control window is open, you cannot execute drive command
controls until the download is complete.
1.6 Purpose of This Manual
This manual describes how to use the WebPakCS software to configure WebPak
3000 drives. Refer to the WebPak 3000 Software Reference instruction manual for
information about parameters.
1.7 Intended Audience
This manual is written for those who must install the WebPakCS software and use the
software to configure and run WebPak 3000 drives. This manual assumes you are
familiar with Windows and makes references to it throughout.
You will need to know the basic Windows functions before using the WebPakCS
software.
!
ATTENTION: Do not run other Windows or DOS software applications
while you are using the WebPakCS software for drive control.
Unexpected machine motion could result. Failure to observe this
precaution could result in severe bodily injury or loss of life.
