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:
•
Drives that have a built-in safety function must be replaced 10 years after first use.
•
A maximum of 3 ms will elapse from when terminals H1 or H2 shut off until the drive switches to the
“
Safe 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 2 ms.
◆
Using the Safe Disable Function
■
Safe Disable Circuit
The Safe Disable circuit has two isolated channels (terminals H1 and H2) that stop the output transistors. The input
can use the internal power supply of the drive.
Set the EDM function to one of the MFDO terminals
[H2-xx = 21 or 121]
to monitor the status of the Safe Disable
function. This is the
“
Safe Disable monitor output function
”
.
