31 POSITIONING INSTRUCTION
31.1 Common Items
Operation at an error or abnormal end
The following describes operation at an error or abnormal end.
Operation at an abnormal end
When operation of the positioning function ends with an error, pulse output is stopped.
• When an error occurs at start of a positioning instruction, pulse output is not started. Pulse output is also not started when a
positioning instruction is executed with pulse output stopped, such as the pulse output stop command is on.
• When an error occurs during pulse output, deceleration stop is performed. To restart the positioning, eliminate the cause of
the error that has caused the stop and then activate the positioning instruction again.
• When pulse output is stopped by an error status, the positioning instruction for the same axis cannot be activated until the
drive contact of the positioning instruction is turned off or until the instruction is eliminated by online change.
• All axes except the one in which an error occurs keep operating normally. This is the same for multiple axes simultaneous
activation using DRVMUL instruction. However, if an error leading to a stop occurs in one axis in interpolation operation,
operation of both the axes are stopped.
• If an error occurs in table operation in the stepping operation or continuous operation, deceleration stop is performed and
the tables that follow are not executed.
Operation at an error
For the errors, refer to Page 781 Error check.
Caution
For the items specific to each positioning instruction, refer to the cautions of each instruction.
For cautions on program creation, refer to Page 555 Cautions for Program Creation.
For cautions on each table operation, refer to the cautions of each control method or the corresponding positioning instruction.
