Position error excessive during position control. Eeoelale5035
When the axis reaches the target position or stops, the target position value and the calculated value are the same. When a new axis movement command starts execution, the NC begins calculating command values (RCON) toward the target value, and this calculation continues until the target position is reached. During axis movement, actual position lags behind the commanded position by a certain amount; the difference between them is called ”following error”. An alarm occurs when following error exceeds the set value.

3182 MCS APA speed overflow
The position encoder count value (RAPA) changes as the motor rotates, and the NC periodically checks the change in position encoder count value.

For example, it occurs when an axis feedrate is abnormally higher than the normal rapid traverse rate, or when an abnormal change occurs in the count value due to a position encoder failure.
