Eeoelale3040
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, this alarm 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.

Check the limit switch (actuated by foreign matter?)
[Measures to Take]
Turn ON the overtravel release switch in the control cabinet in manual mode, then operate the manual pulse generator to move the overtravelled axis away from the limit position.
Then turn OFF the overtravel release switch, press the reset button to recover the system, and reset the user parameter stroke limit.

3-> G21 command was issued without opening the door.
5-> When command G21 HP=4, 5 was issued, there was no target position at the current position while the target position within stroke restricted work area 1 was set in system parameters.
[Probable Cause]
Error in tool change position data or restricted work area 1 setting data, and the G21 HP=* command was issued after checking only one of the data.
At HP=1, the L-tool station is indexed to the tool change position. At 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).
At HP=3, the side machining tool station is indexed to the tool change position.
An alarm occurs if the station mounted with the tool type corresponding to the G21 HP=* command is not indexed to the tool change position.

HP=3 …. T1 is not indexed (rotated) to the ATC position on LB15 II / LB35 II -M
ATC-Y and LU45-MATC-Y turrets.
3-> G21 command was issued without opening the door.
5-> When command G21 HP=4, 5 was issued, there was no target position at the current position while the target position within stroke restricted work area 1 was set in system parameters.
[Probable Cause]
Error in tool change position data or restricted work area 1 setting data, and the G21 HP=* command was issued after checking only one of the data.
At HP=1, the L-tool station is indexed to the tool change position. At 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).
At HP=3, the side machining tool station is indexed to the tool change position.
An alarm occurs if the station mounted with the tool type corresponding to the G21 HP=* command is not indexed to the tool change position.
