Troubleshooting:
Alarm information: 1288 Index worktable releasing/clamping detection overtime (A011.0)
Fault reason: Fail to receive the detection signal within the delay time.
Troubleshooting: Check the signal circuit and ensure the releasing/clamping signal input is normal.
Alarm information: 1289 Index worktable releasing/clamping detection abnormality (A011.1)
Fault reason: Input the releasing/clamping signal at the same time.
Troubleshooting: Check the signal circuit and ensure the releasing/clamping signal input is normal.
Alarm information: 1290 Fail to use the index worktable clamping equipment (A011.2)
Fault reason: When the index worktable clamping equipment does not use (that is, K12.4=0), the
index worktable releasing or clamping motion command is performed.
Troubleshooting: Perform the index worktable releasing or clamping motion command after the
K12.4 is set to 1.
Alarm information: 1291 Fail to rotate because the index worktable does not release (A011.3)
Fault reason: The index worktable rotation is performed when it is on releasing state.
Troubleshooting: Perform the index worktable rotation after it is clamped; or adjust the index
worktable to the debugging mode (that is, K12.6 is set to 1), and then perform the
index worktable rotation operation.
Alarm information: 1292 Fail to move because the index worktable does not clamp (A011.4)
Fault reason: When the index worktable is on releasing state, the feed axis is then performed the
movement operation.
Troubleshooting: Perform the feed axis movement operation after the index worktable is clamped; or
adjust the index worktable to the debugging mode (that is, K12.6 is set to 1), and
then the feed axis is performed the movement operation.
Alarm information: 1293 Do not cycle start because the safety door opens (A011.5)
Fault reason: The cycle start button is controlled in the case of the safety door does not close when
the safety door detection equipment is used (that is, K8.3=1).
Troubleshooting: Perform the cycle start after closing the safety door.
Alarm information: 1294 Fail to shift in the rigid tapping, firstly cancel the rigid tapping and then
shift (A011.6)
Fault reason: Use the spindle shift equipment; do not perform M29 tapping command when the
shifting is not in-position.
Troubleshooting: Firstly cancel the rigid tapping and then perform the shift.
Alarm information: 1360 Low lubrication pressure or grease level (A020.0)
Fault reason:
Troubleshooting: Detect the state of X001.7
Precaution:
