Default Value
0 to 2

Description
Set the value to detect an excessively following error during position control.
The Excessive Deviation (IL
04, bit 9) is set to 1 (ON) if the Position Error (monitoring parameter IL
1A) is
greater than the Error Count Alarm Detection. An excessive error will not be detected if this value is set to 0.
Related Parameters
An excessive error can be set to be treated either as a warning or as an alarm in the Excessive Deviation Error Level Set-
ting in Mode Setting 1 (setting parameter OW
01, bit 0).
OW
01, bit 0 = 0: Alarm (default) (stops axis operation)
OW
01, bit 0 = 1: Warning (continues axis operation)

0
Description
Set the time to detect a positioning time over error.
If the Positioning Completed bit does not turn ON within the time set here after reference pulses have been distributed
during position control, a Positioning Time Over alarm (monitoring parameter IL
04, bit 6) will occur. The comple-
tion of positioning will not be checked if this parameter is set to 0.

Description
Set the phase correction amount in reference units for phase reference commands.
Use this parameter to compensate for reference pulses in control systems without rigidity, in which higher gain cannot be
applied.
Use this parameter as the target position for the cam pattern with incremental addition.
Refer to 6.2.24 Phase References (PHASE) for details on phase reference commands.
