Safety Function
4.5.3 SBC function
■How SBC function works
The SBC function can control the break control signal and
shut off the output to the motor. SBC function links STO
function.
The SBC function can be used by inputting SBC-A or SBC-B
function individually.
When SBC-A and SBC-B are activated at the same time,
SBC-A is higher priority function.
Deceleration time in the SS1 state during SBC sequence is
determined by Deceleration time [oC-10] or [oC-20] in the
setting parameters of SJ-P1.

The setting [1-12]STO-A release mode / [2-12]STO-B
release mode is applied to STO function. Releasing of STO
function during SBC function depends on the activation of
SBC signal input.
Releasing of SBC control signal depends on the setting of
[1-35] SBC-A STO-A release wait time / [2-35] SBC-B STO-B
release wait time and [1-36] SBC-A release level / [2-36]
SBC-B release level.
