Response times of STO function

The entire response time is the time from when a safety-relevant event occurs on the system components (total) until they are in a safe state (stop category 0 in accordance with IEC 60204-1).

Response time	Description
< 1 ms	From the time when the STO inputs are no longer energized Until the time when the motor can no longer generate torque.
< 20 ms	From the time when the STO inputs are no longer energized Until the time when the STO monitoring status changes.
< 20 ms	From detection of a fault in the STO circuit Until display of the fault in the inverter display or the digital output. Status: "Frequency inverter fault"
