Appendix
16. Aborting of Operation 1 (CANC)
Description
Use a declarative command CANC to cause the moving axis to decelerate a stop and cancel the
remaining operation of the axis.
How to Use
While CANC is input, all movement commands issued in the same program are paused are aborted.
CANC command
CANC
20
Abort the movement command in the middle when input port 20 turns ON.
(Declaration)
:
MOVP 1
MOVP 2
:
WTON 21
:
* Declare this command in a step before a movement command.
* While CANC is input, all operation commands are cancelled one by one, but non-operation commands
(such as I/O processes and calculation processes) are performed according to the specified sequence.
Caution
Since which program step is currently executed becomes indeterminable, it is recommended that a WTON
command be used to create a step to wait for input.
Application
With a CANC command, you can select a desired pattern of input signal by using operand 2.
0 = Contact a (Deceleration to a stop)
Same as when operand 2 is not specified
1 = Contact b (Deceleration to a stop)
Input port 20 ON
Remaining
operation
Time
Speed
This operation is cancelled.
Cancellation input: 20 = Contact b

Appendix
17. Aborting of Operation 2 (STOP)
Description
Cause the moving axis to decelerate a stop and cancel the remaining operation of the axis. (STOP)
How to Use
Implement an abort using a STOP command issued from other program. (Multi-tasking mode)
Use an axis pattern to specify the axis you want to abort.
Example of Use 1
STOP command
Main program
Aborting control program
If “STOP 11” is executed while “MOVL 1” is still being executed, “MOVL 1” will be cancelled and
operation will continue from “MOVL 2.”
Example of Use 2
Main program
Aborting control program
If “STOP 10” is executed while “MOVP 1” is still being executed, only axis 2 corresponding to “MOVP
1” will be cancelled. Both axes 1 and 2 will operate from “MOVP 2.”
Caution
In the operation being performed is a CP operation (interpolation operation) started by MOVL, etc., the
operation of all axes will be cancelled regardless of the axis pattern specified by the STOP command.
Time
Input port 20 ON
Remaining
operation
Speed
This operation is cancelled.
Start an aborting program.
Wait for an abort input.
Abort axes 1 and 2.
Wait for an abort input.
Abort axis 2.
