1181 MCS DIFF overflow
The position error in position control is excessive.
When an axis is at the target value (at rest), its target value and calculated value
match the current position. When a new axis movement command is issued, calculation
of the target value begins to generate the calculated value (RCON). At this time, the current position lags behind
the calculated value by a certain delay. This delay amount ([calculated value] - [current position]) is called following error;
an alarm occurs when the following error exceeds the specified allowable value.
