IW00
Bit 1
Running (At Servo
ON)
Indicates the Servo ON status.
1: Power supplied to Servomotor, 0: Power not supplied to Servomotor
IL02 Warning
Stores the most current warning.
IL04 Alarm
Stores the most current alarm.
IW08
Motion Command
Response Code
Indicates the motion command that is being executed.
The response code is 8 during STEP command execution.
IW09
Bit 0
Command Execu-
tion Flag
The Command Execution Flag bit will turn ON during STEP command execution
and then turn OFF when STEP command execution has been completed.
IW09
Bit 1
Command Hold
Completed
Turns ON when a deceleration to a stop has been completed as the result of setting
the Holds a Command (OW09, Bit1) bit to 1 during STEP command execution
(IW08 = 8).
IW09
Bit 3
Command Error
Completed Status
Turns ON if an error occurs during STEP command execution.
The axis will decelerate to a stop if it is moving. Turns OFF when another command
is executed.
IW09
Bit 8
Command Execu-
tion Completed
Turns ON when STEP command execution has been completed.
IW0C
Bit 0
Discharging
Completed
Turns ON when pulse distribution has been completed for the move command.
Turns OFF during execution of a move command.
IW0C
Bit 1
Positioning Com-
pleted
Turns ON when pulse distribution has been completed and the current position is
within the Width of Positioning Completion. OFF in all other cases.
IW0C
Bit 3
NEAR Position
The operation depends on the setting of the NEAR Signal Output Width (setting
parameter OL20).
OL20 = 0: Turns ON when pulse distribution has been completed (DEN =
ON). Otherwise, it turns OFF.
OL20
≠ 0: Turns ON when the absolute value of the difference between
MPOS (IL12) and APOS (IL16) is less than the NEAR
Signal Output Width even if pulse distribution has not been com-
pleted.
OFF in all other cases.
