Safety Precautions
DANGER
Sudden Movement Hazard. Make sure that the full system or machinery in which the Safe Disable function is
used complies with safety requirements. When implementing the Safe Disable function into the safety system of a machine, do
a full risk assessment for the system to make sure that all parts of the system comply with applicable safety standards. Incorrect
application of the Safe Disable function will cause serious injury or death.
DANGER
Sudden Movement Hazard. An external holding brake or dynamic brake are NOT drive safety components.
Systems that use an external holding brake or dynamic brake with a drive output signal (including EDM) are not safe systems
because the drive output signal is not a safety component. You must use a system that satisfies the safety requirements. Failure
to obey will cause death or serious injury.
DANGER
Sudden Movement Hazard. Connect the Safe Disable inputs to the devices as specified by the safety
requirements. Failure to obey will cause death or serious injury.
WARNING
Sudden Movement Hazard. With PM motors, the failure of two output transistors can cause current to flow
through the motor winding and move the motor output axis 180 electrical degrees. This is possible when the Safe Disable
function turns off the drive output. Make sure that output transistors failure will not effect the safety of the application when with
the Safe Disable function. Failure to obey could cause death or serious injury.
WARNING
Electrical Shock Hazard. The Safe Disable function will turn off the drive output, but it will not stop the drive
power supply and it cannot electrically isolate the drive output from the input. Always turn off the drive power supply during
maintenance and installations on the drive input and output sides. Failure to obey could cause death or serious injury.
WARNING
Sudden Movement Hazard. An external gravitational force in the vertical axis will move the motor although the
Safe Disable function is in operation. Failure to obey could cause serious injury or death.
WARNING
Sudden Movement Hazard. Remove the pre-installed wire links between terminals H1-HC and H2-HC to use
the Safe Disable inputs. Failure to obey will prevent correct operation of the Safe Disable circuit and could cause death or
serious injury.
WARNING
Sudden Movement Hazard. Regularly examine the Safe Disable input and all other safety features. A system
that does not operate correctly can cause death or serious injury.
WARNING
Sudden Movement Hazard. Only let approved technicians with full knowledge of the drive, the instruction
manual, and safety standards wire, examine, and maintain the Safe Disable input. Failure to obey could cause death or serious
injury.
NOTICE
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 2 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.
NOTICE
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.
NOTICE
Drives that have a built-in safety function must be replaced 10 years after first use.
■
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 = E or 10E]
to monitor the status of the Safe Disable
function. This is the
“
Safe Disable monitor output function
”
