94 Safety functions
With an encoder
A SBC speed (parameter SBC.15): Speed limit below which FSO activates the SBC
(brake) and drive STO functions while ramping.
B Zero speed with encoder (parameter FSOGEN.52): Speed limit to define the motor as
stopped. The safety function is completed, the ramp monitoring is stopped and the SS1
completed indication (parameter SS1.22) goes on. The acknowledgment becomes
allowed.
C Response time (depends on system configuration, see page 532)
