Z70 Abs posn param restored 0005 (Axis name)
Details
The data has been restored by inputting the parameters during the alarm No.0002.
Remedy
Turn the power ON again to start the operation.
(Note) To release alarm "Z70 Abs data error", enter the parameter data output when establishing the
absolute position and turn ON the power again. For the rotary axis, however, the alarm cannot
be released by entering the parameter data.
- Zero point initialization: Not required
Z70 Abs data error 0006 (axis name)
Details
Deviation of the servo axis with scale when the power is OFF exceeds the set value in "#2051 check
(Check)".
Remedy
Search for the factor which led the deviation of the servo axis at the power OFF.
- Zero point initialization: Not required
- Alarm reset when power is turned OFF: -
- Servo alarm No.: -
Z70 Abs posn error 0007
Detail
The difference of the machine positions at power OFF/ON exceeds the value set in "#2051 check".
The following are the principle cause of error.
1. The machine position was changed.
2. An error of the encoder was detected.
Remedy
Make sure to always carry out the zero point initialization not to lose the absolute position.
Check if the machine position is not changed by moving to the reference position, etc.
When the machine position is not changed, reinitialize the zero point.
The machine may have moved by turning the power OFF.
If the machine position is changed, there may be a trouble with the encoder. Replace the encoder and
reinitialize the zero point.
Z70 Abs posn data lost 0080 (Axis name)
Details
The absolute position data has been lost. An error of the multi-rotation counter data in the detector and
so on may be the cause.
Remedy
Replace the detector and complete zero point initialization.
(Note) To release alarm "Z70 Abs data error", enter the parameter data output when establishing the
absolute position and turn ON the power again. For the rotary axis, however, the alarm cannot
be released by entering the parameter data.
- Zero point initialization: Required
- Servo alarm No.: (9E)etc.
Z70 Abs posn error(servo alm 25) 0101 (Axis name)
Details
The servo alarm No. 25 was displayed and the power was turned ON again.
Remedy
Perform zero point initialization again.
(Note) To release alarm "Z70 Abs data error", enter the parameter data output when establishing the
absolute position and turn ON the power again. For the rotary axis, however, the alarm cannot
be released by entering the parameter data.
- Zero point initialization: Required
- Servo alarm No.: -25
