ABB FSO-21, User Manual

Page: 423 / 540

Parameters 423
Safebus The FSO module expects an external SLS
acknowledgement signal from the safety
fieldbus. The FSO module accepts the
acknowledgement after the SLS request has
been removed and the SLS limit has been
achieved (that is, SLS monitoring is on).
Manual_Safebus The FSO module expects an external SLS
acknowledgement signal either from a digital
input or from the safety fieldbus. The FSO
module accepts the acknowledgement after
the SLS request has been removed and the
SLS limit has been achieved (that is, SLS
monitoring is on).
SLSx.03 SLS activation
monitoring method
Sets the monitoring method that is used in
SLS activation. Ramp
Ramp Ramp monitoring. SAR1 parameters define
the deceleration ramp and monitoring limits.
See parameters
200.112 , SARx.21 ,
SARx.22 and SARx.02 .
Time Time monitoring. The drive (parameter 23.13
or 23.15) defines the deceleration ramp and
it is monitored with parameter SLSx.04 SLS
time delay .
SLSx.04 SLS time delay Sets the latest activation time for SLS
monitoring after an SLS request.
This parameter is relevant only if time
monitoring is used.
See parameter
SLSx.03 SLS activation
monitoring method .
Note: With time monitoring, when
Monitoring active and Modoff delay time are
selected,
SLSx.04 and SLSx.06 time must
be set shorter than STO.14 , otherwise STO
is not activated due to limit hit when drive
modulation is lost with SLS function.
Note: If the value of this parameter is set to
0 ms , SLS monitoring will be started
immediately regardless of the motor speed.

SLSx.05 SLS ramp modoff
reaction
Selects the fault reaction in case the drive
modulation is lost during the SLS
deceleration ramp, when SLS is activated
from speed which is higher than SLS limit
speed.
Note: If encoder feedback is in use,
SLSx.05 parameter has no effect.
