YASKAWA Sigma-7 SGD7S Series

– Warnings are detected for overtravel in the same direction as the ref-
erence.
– Warnings are not detected for overtravel in the opposite direction
from the reference. Example: A warning will not be output for a for-
ward reference even if the N-OT signal turns ON.
– A warning can be detected in either the forward or reverse direction if
there is no reference.
– A warning will not be detected when the servo is turned ON even if
overtravel status exists.
– You can use the ALM_CLR (Clear Alarms and Warnings) command
to clear the warning regardless of the servo ON/OFF status and over-
travel signal status.
– If you clear the warning with the Fault Reset command during over-
travel status, a warning will not be detected again until the overtravel
status is left
– An overtravel warning will be detected even when the software limit
has been detected.
6.11.6 Overtravel Release Method Selection
You can set Pn022 = n.X (Overtravel Release Method Selection) to release over-
travel. Internal limit active (ZSW1 bit 11 in PROFIdrive Position Mode, ZSW1 bit 15 in all
other cases) changes to 1 during overtravel. The motor will not be driven if there is over-
travel in the same direction as the reference.
The PROFINET implementation corresponds to the described setting Pn022 = n.1.
Parameter Meaning When Enabled Classification
Pn022
n.0
(default
setting)
Overtravel exists while
the P-OT or N-OT signal
is being input.
After restart Setup
n.1
Overtravel exists while
the P-OT or N-OT signal
is input and the current
position of the workpiece
is separated* from the P-
OT signal or N-OT
signal.
* Here, “separated” means a position that is further in the positive direction than the P-OT
signal or a position that is further in the negative direction than the N-OT signal.
