4.2 Motion Command Details
4.2.4 INTERPOLATE (Interpolation)
4-44
Monitor Parameters
OL20
NEAR Signal Output
Width
Set this parameter to the value for which bit 3 in IW0C will
change to 1 (Within near position range). Bit 3 changes to 1 when
the absolute value of the difference between the reference position
and the feedback position is within the range that is specified here.
OW
31 Speed Compensation
Set the speed feedforward amount as a percentage of the rated
speed.
The setting unit for this parameter is always 0.01%.
OL38
Linear Deceleration
Rate/Deceleration Time
Constant
Set the positioning deceleration rate with the deceleration time.
This parameter is used for decelerating to a stop when an alarm
occurs.
OW
3A Filter Time Constant
Set the acceleration/deceleration filter time constant.
Exponential acceleration/deceleration or a moving average filter can
be selected in bits 8 to B in OW03. This setting can be
changed only when distribution has been completed (i.e., when bit 0
in IW0C is 1).

IW
00
Bit 1
Running with Servo
ON
This bit shows the Servo status for the axis.
0: Stopped, 1: Running with Servo ON
IL
02 Warnings This parameter reports the current warning status.
IL04 Alarms This parameter reports the current alarm status.
IW08
Motion Command
Response Code
This parameter shows the motion command currently in execution.
This parameter is 4 during execution of the INTERPOLATE command.
IW
09
Bit 0
Command Execu-
tion Flag
This bit is always 0 (Completed) for the INTERPOLATE command.
IW
09
Bit 1
Command Hold
Completed
This bit is always 0 (Command hold not completed) for the INTERPO-
LATE command.
IW09
Bit 3
Command Error End
This bit changes to 1 (Completed with an error) when an error occurs
during execution of the INTERPOLATE command.
The axis will decelerate to a stop if it is moving. This bit changes to 0
(Completed normally) when another command is executed.
IW
09
Bit 8
Command Execu-
tion Completed
This bit is always 0 (Normal execution not completed) for the INTERPO-
LATE command.
IW
0C
Bit 0
Distribution Com-
pleted
This bit changes to 1 (Distribution completed) when the distribution for
the travel motion command is completed.
This bit is 0 (Distributing pulses) when the execution of a travel motion
command is in progress.
IW
0C
Bit 1
Positioning Com-
pleted
This bit is 1 (Within positioning completed range) when distribution is
completed and the current position is within the positioning completed
range. This bit is 0 (Outside positioning completed range) in all other
cases.
IW
0C
Bit 3
Near Position
The operation of this bit depends on the set value of OL20.
If OL20 is 0, this bit is 1 (Within near position range) when distribu-
tion is completed (i.e., when DEN is 1), and it is 0 (Outside near position
range) when distribution is not completed.
When OL20 is not 0, this bit is 1 when within the range of the fol-
lowing formula, regardless of the state of distribution, and 0 in all other
cases.
|(IL12) − (IL16)| ≤ OL20
IL12: Machine Coordinate System Reference Position
IL16: Machine Coordinate System Feedback Position
OL20: NEAR Signal Output Width
