1179 MCS CON velocity over

Eeoelale3039
In position control, the position deviation is excessive.
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 starts calculation for the target value (RCON), and this calculation continues until the target position is reached. During axis movement, there is a certain delay of the actual position relative to the commanded position. The difference between them is called "following error" (droop). When the following error exceeds the set value, this alarm occurs.
