Appendix
Fault reason: When the tool magazine is at the infeed position, and the Z axis is not at the origin,
perform the operation of the tool magazine retraction.
Troubleshooting: Make the Z axis returning to the origin and then retract the tool.
Alarm information: 1262 Exceed the safety position (A007.6)
Fault reason: Tool is at the infeed position, when moving the Z axis, which exceeds the tool-change
position.
Troubleshooting: Make the Z axis coordinate is placed at between the tool-change position and
origin by moving the Z axis.
Alarm information: 1264 Abnormal spindle position mode conversion (A008.0)
Fault reason: Fail to receive the spindle position mode completion signal within the setting time of
the T24 when executing the M29 code.
Troubleshooting: Adjust the setting time by T24 or check whether the spindle position mode
completion signal is output.
Alarm information: 1265 Abnormal spindle velocity mode conversion (A008.1)
Fault reason: Fail to receive the spindle velocity mode completion signal within the setting time of
the T28 when executing the M 28 code.
Troubleshooting: Adjust the setting time by T28 or check whether the spindle position mode
completion signal is output.
Alarm information: 1267 Abnormal tool magazine forward/backward detection (A008.3)
Fault reason: System detects the tool magazine forward in-position signal and tool magazine
retraction in-position signal at the same time.
Troubleshooting: Detect whether the signals both X5.1 and X5.2 are normal, and whether the type
selection of the switch is correct.
Alarm information: 1268 Abnormal spindle releasing/clamping detection (A008.4)
Fault reason: System detects the tool releasing signal and tool clamping signal at the same time.
Troubleshooting: Detect whether the signals both X2.5 and X2.6 are normal, and whether the type
selection of the switch is correct.
Alarm information: 1269 Abnormal spindle orientation time-sequence detection (A008.5)
Fault reason: System has been detected the spindle orientation completion signal before the spindle
orientation operation.
Troubleshooting: Detect whether the signal X7.1 is normal, and whether the type selection of the
switch is correct.
Alarm information: 1270 Do not perform the tool-change when Z axis is not returned to the
mechanical zero (A008.6)
Fault reason: The system performs the M06 or M50 code without executing the Z axis mechanical
zero return operation after it is power on or ESP.
Troubleshooting: Firstly perform the Z axis zero return operation, and then perform the tool-change
