Axis status 'XX(h)' 2 24  
Bit 0 (Servo axis in use): 0 = Not in use / 1 = In use (moving, etc.)
* “Servo axis in use” indicates that a given task has the right to use
the applicable axis. Therefore, this bit will turn ON not only when an
operation command involving axis movement is in progress (including
when an axis is moving), but also in the following conditions:
 Servo is starting up from an OFF state
 Servo is shutting down from an ON state (excluding emergency stop)
 Operation axis is paused
Bits 1, 2 (Home return): 0 = Not yet performed / 1 = Returning to home /
2 = Completed
Bit 3 (Servo): 0 = OFF / 1 = ON
Bit 4 (Operation command successful completion): 0 = Not yet
complete / 1 = Completed successfully
* Can be used only for completion check after an operation command.
(For positioning that includes any of the X, Y and R-axes, be sure to
check completion for all of the X, Y and R-axes.)
Bit 5 (Push error detection): 0 = Not detected / 1 = Detected
Bits 6, 7 (Reserved for system use)
* Check method for operation command positioning under IAI protocol
After an IAI-protocol operation command is executed, turning OFF (Not
in use) of bit 0 (Servo axis in use) will be monitored for the applicable
axis.
When “Not in use” is detected, the cause will be checked based on the
conditions of bit 4 (Operation command successful completion) and bit
5 (Push error detection) (three causes are shown below):
(1) [Bit 0 (Servo axis in use) = OFF] AND [Bit 4 (Operation command
successful completion) = ON]
--- Positioning has completed successfully.
(2) [Bit 0 (Servo axis in use) = OFF] AND [Bit 5 (Push error detection) =
ON]
--- Push error (* Need not be checked if push command is not
used.)
(3) [Bit 0 (Servo axis in use) = OFF] AND [bit 4 (Operation command
successful completion) = OFF] AND [Bit 5 (Push error detection) =
OFF]
--- Operation cancellation due to error, emergency stop, etc.

(Note 1) Add H (or h) at the end of each data expressed in hexadecimal notation. If there is no H or h at the end, the data is considered a decimal.
(Note 2) Data enclosed in single quotation marks indicates an ASCII code. Data is a hexadecimal ASCII code if (h) is added before the closing quotation mark, or a decimal ASCII code if (d) is added before the closing
quotation mark.
