Parameters for Motion Control
Setting Precautions
• When Set to 0
When bit 0 in the IW0C monitor parameter (Distribution Completed) changes to 1
(Completed), bit 3 in the IW0C changes to 1.
• When Not Set to 0
Bit 3 in the IW0C changes to 1 in the following case, regardless of the status of the Dis-
tribution Completed Flag.
|(IL12) − (IL16)| ≤ OL20
IL12: Machine Coordinate System Reference Position (MPOS)
IL16: Machine Coordinate System Feedback Position (APOS)
OL20: NEAR Signal Output Width
• This parameter has no relation to the NEAR Signal Width parameter in the SERVOPACK.

IW0C monitor parameter, bit 3 (Near Position)
Excessive Deviation Detection Value
 Excessive Deviation Detection Value
Set the value to detect an excessive deviation during position control.
Setting Precautions
Bit 9 in the IL04 monitor parameter (Excessive Deviation) changes to 1 (Excessive devia-
tion) in the following case.
|Position Deviation (IL1A)| > Excessive Deviation Detection Value
Excessive deviation is not detected when this parameter is set to 0.
Related Parameters
Bit 0 in the OW01 setting parameter (Excessive Deviation Error Level Setting) can be set
to treat excessive deviation errors as either warnings or alarms.
Bit 0 in OW01 = 0: Treat as an alarm (default). Axis operation stops.
Bit 0 in OW01 = 1: Treat as a warning. Axis operation continues.
Positioning Completion Check Time
 Positioning Completion Check Time
Set the time to detect a Positioning Time Exceeded error.
