(kp/rev)
SV021 OLT
Overload detection
time constant
Set the detection time constant of Overload 1 (Alarm 50).
Set to “60” as a standard. (For machine tool builder adjustment.)
1 to 300
(s)
SV022 OLL
Overload detection
level
Set the current detection level of Overload 1 (Alarm 50) in respect to the
stall (rated) current. Set to “150” as a standard. (For machine tool
builder adjustment.)
50 to 180
(Stall [rated]
current %)
Set the excessive error detection width when servo ON.
Rapid traverse rate

setting value> OD1=OD2=
60*PGN1
/2 (mm)
SV023 OD1
Excessive error
detection width
during servo ON
When “0” is set, the excessive error detection will not be performed.
0 to 32767
(mm)
SV024 INP
In-position
detection width
Set the in-position detection width.
Set the accuracy required for the machine.
The lower the setting is, the higher the positioning accuracy gets,
however, the cycle time (setting time) becomes longer. The standard
setting is “50”.
0 to 32767
(μm)
Parameters with an asterisk * in the abbreviation, such as PC1*, are validated when the NC power is turned ON again.
