WARNING
Sudden Movement Hazard. Do not use the drive output signals to control external
holding brakes or dynamic brakes for functional safety. Use a system that conforms to the functional
safety requirements. Incorrect application of the Safe Disable function can cause serious injury or death.
Systems that use drive output signals (including EDM) for safety are not safe because drive output signals
are not safety components.
WARNING
Sudden Movement Hazard. Connect the Safe Disable inputs to the devices as
specified by the safety requirements. If you connect the Safe Disable inputs incorrectly, it can cause
serious injury or death.
WARNING
Sudden Movement Hazard. To use the Safe Disable inputs, remove the jumpers
between terminals H1-HC and H2-HC. If the Safe Disable circuit does not work correctly, it can cause
serious injury or death.
WARNING
Sudden Movement Hazard. When you clear the Safe Disable input, make sure that
the Safe Disable Monitor output operates correctly as the specification for Safe Disable function. If the
Safe Disable circuit does not operate correctly, it can cause serious injury or death.
WARNING
Sudden Movement Hazard. Regularly examine the Safe Disable input and all other
safety features. A system that does not operate correctly can cause serious injury or death.
WARNING
Sudden Movement Hazard. Only let approved personnel who know about the
drive, instruction manual, and safety standards wire, examine, and maintain the Safe Disable input. If
personnel are not approved, it can cause serious injury or death.
WARNING
Sudden Movement Hazard. Only use the Safe Disable Monitor (multi-function
output terminal set to the EDM function) to monitor the Safe Disable status or to find a malfunction in the
Safe Disable inputs. The monitor output is not a safety output. If you use the Safe Disable Monitor
incorrectly, it can cause death or serious injury.
Note:
•
When you use a drive with a built in safety function, you must replace it 10 years after first use.
•

“

Torque Off
”
status. Set the OFF status for terminals H1 and H2 to hold for at least 3 ms. The drive may not be
able to switch to the
“
Safe Torque Off
”
status if terminals H1 and H2 are only open for less than 3 ms.
