1153 MCS CON APA deviation
Eeoelale3011
The deviation between CON (command position) and APA (actual position) exceeded the set value.
The deviation (DIFF) between CON and APA is also called "following error". It is equal to the absolute value of the difference between the command position value written to the MCS and the actual position value read from the MCS. The NC control software monitors this deviation during axis movement. This alarm is issued when a serious failure occurs in the inverter unit and this deviation cannot be monitored.

In position control, the position error is excessive.
When an axis reaches the target position or stops, the target position value and the calculated value are identical. 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, actual position lags behind the commanded position with a certain delay. The difference between them is called "following error" (diff). When the following error exceeds the set value, this alarm occurs.

[Probable Fault Cause]
Operation or programming error
Incorrect setting of variable soft-limit position (positive/negative)
(Variable soft-limit position is outside the stroke end limit)
Check the stroke limit switch (Has any foreign matter actuated it?)
[Remedy]
Turn on the overtravel release switch inside the electrical control cabinet in manual mode, then operate the manual pulse generator to move the overtraveled axis away from the stroke limit position.
Then turn off the overtravel release switch, press the reset button to restore the system to normal, and reset the variable soft-limit position.

after cycle start following a reset does not match that of sequence restart.
[Target]
SYSTEM
[Probable Fault Cause]
The program contains a conditional statement that changed the sequence number to be executed.
The conditional statement is evaluated depending on whether the conditional expression is true or whether a local variable is defined.
Program example:
N0018 IF ABCD N0020
N0019 ABCD=1 <- Define local variable.
N0020
At the first program execution, sequence number N0019 is executed because local variable ABCD does not exist. However, after sequence restart, sequence number N0019 is not executed.

1345 Tool change position movement impossible
Eeoelale3097 G21 command to move to the tool change position was issued when execution conditions were not satisfied (G21 is also commanded when executing ATC macros G171 and M321).
[Code]
X
1-> When G21 HP=1, 2, 3 was commanded, the target position is not at the current position but within stroke end limit 1 set in system parameters, or the turret is in the following indexing state:
HP=1 …. Turret is not indexed to the ATC position.

3-> G21 was commanded without opening the door.
5-> When G21 HP=4, 5 was commanded, the target position is not at the current position but within stroke end limit 1 set in system parameters.
[Probable Fault Cause]
The tool change position data or stroke end limit 1 setting data is incorrect, but G21 HP=* was commanded after checking only one of the data.
With HP=1, the L-tool station is indexed to the tool change position. With HP=2, the face tool station is indexed to the tool change position (with MacTurn, the M-tool spindle station is indexed to the tool change position).
With HP=3, the side machining tool station is indexed to the tool change position.
If the station corresponding to the tool type commanded by G21 HP=* is not indexed to the tool change position, an alarm occurs.
An alarm occurs if G21 HP=* is commanded when the turret indexing conditions are not satisfied.
An alarm also occurs if G21 HP=* is commanded when the door is not open.
