[ b ] Monitoring Parameters
Parameter Name Monitor Contents SVR
IW00
Bit 1
Running (At Servo
ON)
Indicates the Servo ON status.
1: Power supplied to Servomotor, 0: Power not supplied to Servomotor
IL02 Warning
Stores the most current warning.
IL04 Alarm
Stores the most current alarm.
IW08
Motion Command
Response Code
Indicates any alarms that have occurred during execution.
The response code is 6 during LATCH operation.
IW09
Bit 0
Command
Execution Flag
Always OFF for LATCH operation.
IW09
Bit 1
Command Hold
Completed
Always OFF for LATCH operation.
IW09
Bit 3
Command Error
Completed Status
Turns ON if an error occurs during LATCH operation. The axis will decelerate to a
stop if it is moving. Turns OFF when another command is executed.
IW09
Bit 8
Command
Execution
Completed
Always OFF for LATCH operation.
IW0C
Bit 0
Discharging
Completed
Turns ON when distribution has been completed for the move command.
Turns OFF during execution of a move command.
IW0C
Bit 1
Positioning
Completed
Turns ON when distribution has been completed and the current position is within the
Width of Positioning Completion. OFF in all other cases.
IW0C
Bit 2
Latch Complete
This bit turns OFF when a new latch command is executed and turns ON when the
latch has been completed. The latched position is stored as the Machine Coordinate
System Latch Position (LPOS) (monitoring parameter IL18).

IW0C
Bit3
NEAR Position
The operation depends on the setting of the NEAR Signal Output Width (setting
parameter OL20).
OL20 = 0:Turns ON when pulse distribution has been completed (DEN = ON).
Otherwise, it turns OFF.
OL20
≠ 0:Turns ON when the absolute value of the difference between MPOS
(IL12) and APOS (IL16) is less than the NEAR Signal Out-
put Width even if pulse distribution has not been completed.
OFF in all other cases.
IL18
Machine Coordi-
nate System Latch
Position (LPOS)
Stores the current position in the machine coordinate system when the latch signal
turned ON.
