Network Control of Safe Torque-Off Chapter 6
Replacement with “Configure Always” Enabled
When the Configure Always feature is enabled, the controller automatically
checks for and connects to a replacement drive that meets all of the following
requirements:
• The controller has configuration data for a compatible drive at that
network address.
• The drive is in the Out-of-box condition or has an SNN that matches the
configuration.
If the project is configured for Configure Always, follow the appropriate steps to
replace a PowerFlex 527 drive.
Follow these steps when the Configure Always feature is enabled.
1. Remove and replace the existing integrated safety drive.
2. Right-click the replacement drive and choose Properties.
ATTENTION: Enable the Configure Always feature only if the entire integrated
safety control system is not being relied on to maintain SIL 3 behavior during
the replacement and functional testing of a PowerFlex 527 drive. Do not place
drives that are in the Out-of-box condition on an integrated safety network
when the Configure Always feature is enabled, except while following this
replacement procedure.
If Then
The drive is in the Out-of-box condition Go to step 6.
No action is needed for the GuardLogix controller to take
ownership of the drive.
An SNN mismatch error occurs Go to the next step to reset the drive to the Out-of-box
condition.
