AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
This section gives the timing charts to show the operation timing to a safe state as well as the timing of
return from safe state.
The Servo Drive goes into the STO status when either safety input 1 or 2 turns OFF.
The dynamic brake operates according to the setting of the Stop Selection – Shutdown Option Code
(3B20-01 hex).
