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 en-
coder 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 de-
tector 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 estab-
lishing 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 estab-
lishing 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
Z70 Abs posn error(servo alm E3) 0106 (Axis name)
Details
The servo alarm No. E3 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 estab-
lishing 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.: (E3)
Z71 AbsEncoder:Backup voltage drop 0001 (Axis name)
Details
Backup voltage in the absolute position detector dropped.
Remedy
Replace the battery, check the cable connections, and check the detector. Turn the power ON
again and perform zero point initialization.
- Zero point initialization: Required
- Alarm reset when power is turned OFF: -(Z70-0101 is displayed after the power is turned
ON again.)
- Servo alarm No.: 25
Z71 AbsEncoder: Commu error 0003 (Axis name)
Details
Communication with the absolute position detector has been disabled.
Remedy
Check and replace the cables, card or detector. Turn the power ON again and perform zero
point initialization.
- Zero point initialization: (Required) only when the detector has been replaced.
- Alarm reset when power is turned OFF: Reset
- Servo alarm No.: 91
Z71 AbsEncoder: Abs data changed 0004 (Axis name)
Details
Absolute position data has been changed at the absolute position establishment.
Remedy
Check and replace the cables, card or detector. Turn the power ON again and perform zero
point initialization.
- Zero point initialization: (Required) only when the detector has been replaced.
- Alarm reset when power is turned OFF: Reset
- Servo alarm No.: 93
Z71 AbsEncoder: Serial data error 0005 (Axis name)
Details
An error of the serial data was found in the absolute position detector.
Remedy
Check and replace the cables, card or detector. Turn the power ON again and perform zero
point initialization.
- Zero point initialization: (Required) only when the detector has been replaced.
- Alarm reset when power is turned OFF: Reset
- Servo alarm No.: 92
