Description

The Position Error is the difference between the Target Position and Actual Position. If this value exceeds the Position Error Tolerance while controlling in Position PID, the Following Error bit will be set. If the Following Error bit is set, a Halt will occur if the Following Error Auto Stop is configured to do so and the Direct Output Status bit is off.

The Position Error Term is useful for troubleshooting when included in a plot.
