When the Safe Disable function is triggered during run, close the circuit between terminals H1-HC and H2-HC
to disable "Safe Torque Off" after clearing the Run command. Enter the Stop command, then enter the Run
command when terminals H1 and H2 are ON or OFF.

Safety Function Status Monitor
The drive Safety monitor output sends a feedback signal about the status of the Safety function. The Safety
monitor output is one of the possible settings available for the MFDO terminals. If there is damage to the Safe
Disable circuit, a controller (PLC or safety relay) must read this signal as an input signal to hold the "Safe Torque
Off" status. This will help verify the condition of the safety circuit. Refer to the manual for the safety device for
more information about the Safety function.
It is possible to switch polarity of the Safety monitor output signal with the MFDO function settings.
Keypad Display
If the two input channels are OFF (Open), the keypad will flash STo [Safe Torque OFF].
If there is damage to the Safe disable circuit or the drive, the keypad will flash SToF [Safe Torque OFF
Hardware] when one input channel is OFF (Open), and the other is ON (Short circuit). When you use the Safe
disable circuit correctly, the keypad will not show SToF.
If there is damage to the drive, the keypad will show SCF [Safety Circuit Fault] when the drive detects a fault in
the Safe disable circuit. Refer to the chapter on Troubleshooting for more information.
Validating the Safe Disable Function
After you replace parts or do maintenance on the drive, first complete all necessary wiring to start the drive, then
test the Safe Disable input with these steps. Keep a record of the test results.
• When the two input channels are OFF (Open), make sure that the keypad flashes STo [Safe Torque OFF], and
make sure that the motor is not running.
• Monitor the ON/OFF status of the input channels and make sure that MFDO set to the EDM function operates
correctly.
If one or more of the these items are true, the ON/OFF status of the MFDO may not display correctly on the
keypad:
– Incorrect parameter settings.
– A problem with an external device.
– The external wiring has a short circuit or is disconnected.
– There is damage to the device.
Find the cause and repair the problem to correctly display the status.
• Make sure that the EDM signal operates during usual operation.
