7.9 Fast stops requiring acknowledgment
The product offers a so-called Fast Stop to put the product into a
defined state in case of an error or malfunction. Fast Stops are
displayed by setting the SF_FAST_STOP flag in the status word. If a fast
stop is triggered, for example due to an insufficient voltage error, then
all movement commands will be rejected until the error is
acknowledged and any fault condition has been cleared, with
corresponding error codes being returned (access denied). If the
product is in Fast Stop state, power will be removed from the drives
but the position reference will be retained.
The error can be acknowledged both via the command interface (the
command is: Acknowledging a Fast Stop or fault Condition, 24h) as
well as manually by clicking on the "Ack" button in the side bar of the
web interface Status word [

script or manually via the web interface.
