0879 MCS CON speed over

The increment of position command (SRCON) sent from the NC to the inverter unit exceeded the allowable value.
If this alarm occurs on a positioning axis, the servo data file may be erroneous (because the position command increment is calculated by the inverter unit).

Absolute value of position command increment during acceleration/deceleration [(pr/65536)/Tp]
Here, pr = 1 rev of position encoder; Tp = position control cycle
However, the following codes have specific meanings:
1: Error detected during pre-check because position increment value is too large.
2: Position command value (SRCON) exceeds the absolute value of the encoder measurement range. (Linear axis only).

0881 MCS DIFF overflow
Eeoelale2071
Excessive positioning error caused during axis movement.
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 calculation for the target value, the command value
(RCON). This calculation continues until the target position is reached. During axis movement, there is a delay in the actual position relative to the commanded position; this difference is called the "following
error". When the following error exceeds the set value, this alarm occurs.

The position encoder count (RAPA) changes with motor rotation.
The NC periodically checks the change in position encoder count.
This alarm occurs when the amount of change per unit time exceeds the set allowable range.
For example: This alarm occurs when an axis feedrate is abnormally higher than the normal rapid feedrate, or when the count value changes abnormally due to a position encoder failure.

Amount of change in position detection value per position control cycle (absolute value) [position encoder 1/65536 rev / position control cycle]
The following code values have specific meanings:
1 = Linear axis overtravel.
2 = Rotary axis overtravel (360 degrees), or position data of limited-travel axis is negative.
3 = Limited-travel axis overtravel.
