ABB FSO-21, User Manual

Page: 413 / 540

Parameters 413
Delayed brake Time controlled brake. Parameter SBC.12
STO SBC delay defines the delay.
Speed limit The brake is activated below a user-defined
speed limit (parameter
SBC.14 STO SBC
speed ). Requires that an encoder is used.
Note : If an encoder or FSE failure occurs,
and the STO function is not active, the FSO
module starts to use the
Delayed brake
setting. If the STO function is already active,
the action depends on the value of
parameter
S_ENCGEN.11 FSE diagnostic
failure reaction . See section How to
configure STO with speed limit activated
SBC
on page 337 .
SBC.12 STO SBC delay Sets the time when the SBC function will be
activated in relation to the activation of the
STO function. A negative value means that
the FSO module activates the SBC before
the drive STO function.
If the value is
0 ms , the FSO activates the
drive STO and SBC functions at the same
time.
STO function and SSE with immediate STO:
This parameter is valid if parameter
SBC.11
STO SBC usage has value Delayed brake .
SSE with emergency ramp and SS1
function: This parameter is valid if parameter
SBC.15 SSE/SS1 SBC speed is not zero.
Only a negative value and zero are used. If
the value is positive, it is regarded as zero.
Note: You must include the mechanical
brake delays in this value.
