3.4 Motion Parameter Details
3.4.2 Setting Parameter Details
Position deviation
Positioning Time
Exceeded signal
Setting Precautions
• If, during position control, the IW0C monitor parameter does not change to 1 (Within
positioning completed range) even after the time that is set for this parameter is exceeded
from when distribution is completed, a Positioning Time Exceeded alarm occurs (bit 6 in
IL04 changes to 1).
• If this parameter is set to 0, the above check is not performed.
Phase Compensation Setting
 Phase Compensation Setting
Set the phase bias in reference units to use when the PHASE (Issue Phase Reference) motion
command is executed.
Refer to the following section for details on the PHASE command.
PHASE (Issue Phase Reference) on page 4-99

OL28 Phase Compensation Setting
Setting Precautions
• Use for an Electronic Shaft
Use this parameter to compensate for references in a control system without rigidity, in which
higher gain cannot be applied.
• Use for an Electronic Cam
Use this parameter as the target position for the cam pattern.
Latches
 Latch Zone Lower Limit Setting and
Latch Zone Upper Limit Setting
Set the zone (from the zero position to the specified position) where the latch signal is valid
when the EX_POSING (External Positioning) motion command is executed.
If bit 4 in the OW09 setting parameter (Latch Zone Enable) is set to 1 (Enabled) when the
EX_POSING command is executed, latching is performed in the zone between OL2A and
OL2C.
