Position error during position control is excessively large.
When an 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 the command value (RCON) toward the target value.
This calculation continues until the target position is reached. During axis movement, the actual position lags behind the command position by a certain delay; the difference between them is called "following error". An alarm occurs when the following error exceeds the set value.

4182 MCS APA velocity over
Eeoelale6038
The position encoder count value (RAPA) changes as the motor rotates. The NC periodically checks the change in the position encoder count value.
This alarm occurs when the amount of change per unit time exceeds the set allowable range. For example, it occurs when the feedrate of an axis is abnormally higher than the normal rapid feedrate, or when the count value changes abnormally due to a position encoder failure.
