13 Smart Safety Observation Alarm (V)
170 IB-1501279-H
Details
The command/FB speed has failed to decelerate to the safely-limited speed(*) or lower within a period of SLS
deceleration observation time (set by parameter) after start of SLS observation.
The screen displays the name of axis of this error.
(*)Safely-limited speed = SLS speed tolerance x SLS speed override / 100
Remedy
 This error can be cancelled by the safety reset signal while motor speed is under SLS limit.
 If the SLS speed tolerance or SLS speed override (set by parameter) is lower than the assumption, change
the parameter setting and turn OFF and ON the power.

If the SLS deceleration observation time (set by parameter) is shorter than the assumption, change the
parameter setting.
Details
The command position/FB position has gone out of the SLP position tolerance range (set by parameter) during
the SLP observation, and failed to return to the tolerance range within the SLP detection delay time (set by
parameter).
The screen displays the name of axis of this error.
Remedy
 This error can be cancelled by the safety reset signal while the axis is in the SLP position range.
 If the axis is out of the SLP position range, deactivate SLP observation, cancel this error using the safety
reset signal, and then move the axis to a safe position in a manual mode.
 If the safely-limited position range (specified by the SLP position tolerance parameters) is smaller than the
assumption, change the parameter settings and turn OFF and ON the power.
 If the SLP detection delay time (set by parameter) is shorter than the assumption, change the parameter
setting.
 Check the safety ladder to make sure that SLP position tolerance is changed in a timely manner.
Details
The command/FB speed, which had exceeded the SOS stop speed (set by parameter) during SOS, has failed
to drop to the SOS stop speed or lower within the SOS_V detection delay time (set by parameter).
The screen displays the name of axis of this error.
*If the conditions of two or more SOS-related alarms are met at a time, the notification priority order is as fol-
lows: SOS position deviation error > SOS travel distance error > SOS speed error.
Remedy
 This error can be cancelled by the safety reset signal while In SOS stop is ON.

If In SOS stop is OFF, deactivate SOS, cancel this error using the safety reset signal, and then move the
axis to a safe position in a manual mode.

If the parameter of SOS stop speed is lower than the assumption, change the setting and turn OFF and
ON the power.
 If the SOS_V detection delay time (set by parameter) is shorter than the assumption, change the param-
eter setting.
Details
The position deviation (difference between the command and FB positions), which had exceeded the SOS po-
sition deviation tolerance (set by parameter) during SOS, has failed to reduce to the SOS position deviation
tolerance or smaller within the SOS_PD detection delay time (set by parameter).
The screen displays the name of axis of this error.
*If the conditions of two or more SOS-related alarms are met at a time, the notification priority order is as fol-
lows: SOS position deviation error > SOS travel distance error > SOS speed error.
Remedy
 Refer to the corrective actions of "SOS speed error" for how to cancel this error.
 If the SOS position deviation tolerance (set by parameter) is smaller than the assumption, change the set-
ting and turn OFF and ON the power.
 If the SOS_PD detection delay time (set by parameter) is shorter than the assumption, change the param-
eter setting.
