Instruction Status
You can check the error status with the system variable #L_ExIOSpParmErr (special I/O parameter error).
31.5.1.3 Special I/O System Variables
Enabling condition
While the instruction is in operation and when the parameter has been changed.
If no error has occurred (refer to the following notes).
Disabling condition
While the instruction is in operation, after creation of the Acceleration/deceleration pulse table is complete, and the parameter change completion flag turns off.
*When disabled, operand D1 is cleared to 0.
Notes
You cannot create the Acceleration/deceleration pulse table while outputting the acceleration/deceleration pulse. An error occurs if you execute the instruction while outputting the acceleration/deceleration pulse.
While executing the instruction, creating the Acceleration/deceleration pulse table is monitored. If the table is being created, an error occurs and no process will be performed.
When there is a problem with creating an Acceleration/deceleration pulse table, an error occurs.
When the operand D1 cannot be recognized in the instruction, an error occurs.
When executing the instruction using the pulse (for example, PT instruction), you need to turn the instruction OFF and then turn it ON to execute it again.
When the instruction is executed, it will be in operation.
If the instruction is in operation, the instruction will be executed continuously regardless of the enabling/disabling condition.
