Choose Integrated or Hard-wired Safety
When a safety option module is installed in the PowerFlex 755 On-Machine
Drive, you must decide if you want to use integrated (network) safety or
hardware-based (hard-wired) safety.
1. Double-click your drive in the Controller Organizer to open the drive
Module Properties.
2. On the Overview page, click Device Definition to review the drive
settings.
3. Observe the Connection type.
• If the drive connection type is Standard (hard-wired), the safety
option module I/O connection that is shown on the electrical
schematics must be wired to an appropriate safety I/O device or
safety relay via the receptacle that is labeled SO to provide the safety
function.
