B–63980EN/01
56
1828 Positioning deviation limit for each axis in movement
[Data type] 2–word axis
[Unit of data] Detection unit
[Valid data range] 0 to 99999999
Set the positioning deviation limit in movement for each axis.
If the positioning deviation exceeds the positioning deviation limit during
movement, a servo alarm is generated, and operation is stopped
immediately (as in emergency stop).
Generally, set the positioning deviation for rapid traverse plus some
margin in this parameter.
1829 Positioning deviation limit for each axis in the stopped state
[Data type] Word axis
[Unit of data] Detection unit
[Valid data range] 0 to 32767
Set the positioning deviation limit in the stopped state for each axis.
If, in the stopped state, the positioning deviation exceeds the positioning
deviation limit set for stopped state, a servo alarm is generated, and
operation is stopped immediately (as in emergency stop).
1830 Axis–by–axis positional deviation limit at servo–off time
[Data type] 2–word axis
[Unit of data] Detection unit
[Valid data range] 0 to 99999999
This parameter is used to set a positional deviation limit at servo–off time,
on an axis–by–axis basis.
If the value specified with this parameter is exceeded at servo–off time, a
servo alarm (No.410) is issued to cause an immediate stop (same as an
emergency stop). Usually, set the same value as a positional deviation at
stop time (parameter No.1829).
NOTE
When this parameter is set to 0, no positional deviation limit
check is made at servo–off time.
1836 Servo error amount where reference position return is possible
[Data type] Byte axis
[Unit of data] Detection unit
[Valid data range] 0 to 127
This parameter sets a servo error used to enable reference position return
in manual reference position return.
In general, set this parameter to 0. (When 0 is set, 128 is assumed as the
default.)
