3. Download the new configuration to the controller.
The drive display may show fault code “SAFE FLT S03 - SAFE TORQUE
OFF”.
4. Turn off incoming power to the drive.
5. Remove the Safety Bypass jumper.
6. Turn on incoming power to the drive.
Any display fault should now be cleared.
Safety Application Requirements
Creating, recording, and verifying the safety signature is also a required part of
the safety application development process. Safety signatures are created by the
safety controller. The safety signature consists of an identification number, date,
and time that uniquely identifies the safety portion of a project. This signature
covers all safety logic, data, and safety I/O configuration.
For safety system requirements, including information on the safety network
number (SNN), verifying the safety signature, and functional verification tests
refer to the GuardLogix 5570 Controller Systems Safety Reference Manual,
publication
1756-RM099 .
Network Safe Torque-off Specifications
Safe Torque-off Assembly Tags
With network control, a 1756-L7xS GuardLogix safety controller controls the
PowerFlex STO function through the SO.SafeTorqueOff tag in the safety output
assembly.
The SO.Command tags are sent from the GuardLogix's safety output assembly to
the PowerFlex 527 to control the safe torque-off function.
The SI.Status tags are sent from the PowerFlex 527 to the GuardLogix safety
input assembly and indicate the status of the PowerFlex 527's safety control.
IMPORTANT
You must read, understand, and fulfill the requirements detailed in this
publication prior to operating a safety system that uses a GuardLogix controller
and PowerFlex 527 drive.
