Example) Code displays 8000
Converted to octal
8000 (hexadecimal) -> 100000 (octal)
Since the E8 unit is 5 bits, the 6th digit is ignored.

With motor rotation, the position encoder value (RAPA) changes, and the amount of change in the position encoder value is checked at regular intervals.
The feedrate of each axis is compared with the normal rapid traverse rate. This alarm occurs if the amount of change per unit time continuously exceeds a specified allowable value due to abnormally high speed or abnormal value changes caused by a defective position encoder.
Index: Axis
String: None
Code: Hexadecimal value of the position encoder change amount [basic unit/speed control time]
However, the following values have special meanings:
FFFFFFFF = Linear axis stroke over.
FFFFFFFE = Rotary axis stroke over (360 deg), or limited axis is negative.
FFFFFFFD = Limited axis stroke over.
Probable Faulty Locations:
1 Encoder for the axis, or encoder connecting cable
2 Motor for the axis
3 D/U for the axis
4 SVP hardware for the axis

When an axis reaches the target value and stops, the target value, calculated value, and actual position match.
However, when a new axis movement command is commanded, calculation of the new target value starts and the calculated value (RCON) is computed. At the same time, the amount of change in the computed calculated value is monitored at regular intervals, and this alarm occurs if the amount of change varies abnormally for some reason and exceeds the specified allowable value.
Index: Axis
String: None
Code: Hexadecimal value of absolute speed command [encoder unit/speed control time]
However, the following values have special meanings:
FFFFFFFF = NC protocol violation (timing specification).
FFFFFFFE = Speed command exceeds overflow alarm level, or exceeds alarm detection level.
FFFFFFFC = SVP internal command position exceeds encoder assigned stroke.
Probable Faulty Locations:
1 Servo parameters for the axis
2 Control software such as NC
3 SVP hardware for the axis

1008 SVP DIFF over
1008 SVP DIFF over

The actual position follows the calculated value with a certain delay. This delay amount (| [Calculated value] - [Actual position] |) is called tracking error. If this error exceeds a specified allowable value, this alarm occurs.
Index: Axis
String: None
Code: Hexadecimal value of the absolute DIFF [encoder unit]

Converted to octal (Upper E8 unit of type F and E encoders carries over in octal)
12351 12251
Detected bit data Calculated data
Since the 3rd digit differs by 1, the cause can be determined to be the 3rd bit or the 2nd bit that outputs the carry bit signal (phase shift in gear connection).
Index: Axis
String: None
Code: YYYYZZZZ

YYYY = Upper hexadecimal digits read from encoder
ZZZZ = Upper hexadecimal digits calculated from lower digits
Probable Faulty Locations:
