 If both the axis direction and encoder direction are incorrect, reverse both the
encoder direction and axis rotation values.
4.4.9 Follow In-position Waiting Timeout
Reason
 The value of INposition Tolerance is too small.
 Calibration data error.
 Influence of external slag discharge during machining.
 Follow overshooting.
Solution
Follow the steps below to help troubleshoot:
 Check the INposition Tolerance value.
The recommended value is 0.1.
 Execute Execute Calibration again.
 Adjust the cutting technic settings.
 Check the follow parameters and drive parameter settings.
Ensure that they are set correctly.
4.4.10 Large Follow Error Alarm
Reason
Within a certain period of time, the follow error is larger than the out-of-edge tolerance
setting.
Solution
Follow the steps below to help troubleshoot:
 If this alarm was reported when the material surface is quite flat, it may have been
caused by follow overshooting. In this case, check the servo drive gain value.
If the value is too small, increase it as needed.
 If this alarm was reported during cutter lifting, the follow gain value may have been
too small.
4.4.11 System Reports Material Collision Alarm when Follow is Enabled in Idle Status or
During Machining
Reason
The current capacitance is equal to or smaller than the Touch Part Capacitance value.
Solution
Follow the steps below to help troubleshoot:
1. Set Touch Part Capacitance to a proper value.
It is recommended that you use the default value (0).
2. If the alarm is reported when enabling the follow function:
a. Ensure that Pulse Equivalent, Feedback Pulse Count, Speed Gain are set
correctly.
b. Ensure that the drive gain parameter is set correctly.
3. If the alarm is reported during machining:
a. Ensure that there is no exception under manual following.
b. Ensure that the capacitance change during blowing is less than 50.
4. If the alarm is still reported, increase the servo drive gain as needed.
