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. Refer to Table 1.11 for setting instructions.
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.
