■Status of I/O signals at startup and error detection
• At startup
After power-on, each output device constantly outputs the OFF signal until completion of the diagnosis. After the diagnosis is
completed, the devices assigned with [Pr. PSD08 Output device selection DO1] are output.
The diagnosis completion timing differs depending on whether safety sub-function control is by an input device or by a
network. For safety sub-function control by input device, refer to the following.

• At error detection
When an error is detected in a servo amplifier and an alarm that disables SSM occurs, each output device turns off.
If some other type of alarm occurs, the output from the assigned devices will continue.
