( 18 ) Deviation Abnormal Detection Value
OL22
Error Count Alarm Detection
Set the value to detect an excessively following error during position control.
The Excessive Deviation bit (IW04, bit 9) turns ON if the result from subtracting the Machine Coordinate System
Feedback Position (monitoring parameter IL16) from the Machine Coordinate System Reference Position (monitor-
ing parameter IL12) is greater than the NEAR Signal Output Width. An excessively following error will not be
detected if this value is set to 0.
Description
 Related Parameters
An excessively following error can be set to be treated either as a warning or as an alarm in the Excessive Deviation Error
Level Setting 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)
( 19 ) Position Compensation
OL24
Position Correction Setting
Set the position compensation amount in reference units.
Description
( 20 ) Position Complete Timeout
OW26
Position Completion Check Time
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
( 21 ) Phase Compensation
OL28
Phase Correction Setting
Set the phase compensation in reference units for phase reference commands.
<Using as Electronic Shaft>
Use this parameter to compensate for reference pulses in control systems without rigidity, in which higher gain cannot be
applied.
Description
<Using as Electronic Cam>
Use this parameter as the target position for the cam pattern with incremental addition.
 Refer to 7.2.11 Phase References (PHASE) on page 7-81 for details on phase reference commands.
