with a restart on page 48.

INFO
Equal inputs in terms of their functionality
The inputs STOA and STOB are absolutely equal in terms of their functionality, which is why the switching sequence of STOA/
STOB is interchangeable in all of the diagrams.
8.11.2.1 Time response of the STO activation during operation with a restart
The illustration shows the time response starting with the disconnection of the control voltage at STOA/B and the sequence
that is necessary for restarting the device.
▪ The actuation of the holding brake is realised via the basic device and not in a safety-oriented manner.
▪ The illustration shows the coasting of the motor regardless of the activation/deactivation of the brake
▪ The setpoint will not be enabled until the holding brake delay TF has elapsed.
▪ An error will be issued as the STO inputs are deactivated while the output stage is active. It is not included in the drawing.
