1. AXIS CONTROL
49
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
[Unitofdata] 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).
1832 Feed stop positioning deviation for each axis
[Data type] Two--word axis
[Unitofdata] Detection unit
[Valid data range] 0 to 99999999
Set the feed stop positioning deviation for each axis.
If the positioning deviation exceeds the feed stop positioning deviation
during movement, pulse distribution and acceleration/deceleration
control are stopped temporarily. When the positioning deviation drops to
the feed stop positioning deviation or below, pulse distribution and
acceleration/deceleration control are resumed.
The feed stop function is used to reduce overshoot in acceleration/
deceleration mainly by large servo motors.
Generally, set the middle value between the positioning deviation limit
during movement and the positioning deviation at rapid traverse as the
feed stop positioning deviation.
1850 Grid shift for each axis
[Data type] Two--word axis
[Unitofdata] Detection unit
[Valid data range] --99999999 to +99999999
A grid shift is set for each axis.
To shift the reference position, the grid can be shifted by the amount set in
this parameter. Up to the maximum value counted by the reference
counter can be specified as the grid shift.
NOTE
When this parameter has been set, the power must be
turned off before operation is continued.
