SSE with speed limit activated SBC
In these examples, the SBC and drive STO functions are activated at a user-defined
speed limit.
With time monitoring
The operation of the SSE with speed limit activated SBC and time monitoring is
described in the time diagram and table below. For configuration, see section
configure SSE with speed limit activated SBC
on page
A
SBC speed (parameter
): Speed limit below which the FSO activates SBC
(brake) and drive STO functions while ramping.
B
): Time after which the FSO activates the drive
STO function regardless of the motor speed.
C
SBC time to zero (parameter
): Time from the SBC activation to the moment
when the safety function is completed and the SSE completed indication (parameter
) goes on. The acknowledgment becomes allowed. You must set this to the
estimated time in which the motor brakes to a stop from the maximum speed.
D
Response time (depends on system configuration, see page
