The inertia calculator allows a user to automatically calculate the inertia of a load. Sometimes the initial test settings are not sufficient. Incorrect test settings can cause errors. When an error occurs, the inertia calculator will supply an error value. The problems usually occur when the range of travel is too small, excitation signal is not high enough for the load or the speed is too low.
REMEDIES
1. Speed too low (with reverse operation.)
Increase maximum speed and adapt travel range.*
2. Speed too low (with continuous operation.)
Increase maximum speed.
3. Test movement missing.
A test movement is important for drives with high friction or with mechanical slack points (play).
4. No error detected.
Please note the Boundary conditions.
5. Speed too low and amplitude of the excitation signal too small (with reverse operation.)
Increase amplitude of the excitation signal; increase maximum speed and adapt travel range.*
6. Speed too low and amplitude of the excitation signal too small(with continuous operation.)
Increase amplitude of the excitation signal; increase maximum speed.
7. Test movement missing. The amplitude of the excitation signal too small.
Increase amplitude of the excitation signal and or activate an appropriate test movement.
8. Amplitude of the excitation signal too small.
Increase the amplitude of the excitation signal.
9. Following error occurred.
Increase the parameter "permissible following error" or decrease the amplitude of the excitation signal.
10. Waiting for Trigger.
If using increments or degrees and using oscillating for the type of move, upgrade to 9-70 firmware, available for free download. For EPL & EtherCAT for units of increments, there was a bug in previous firmware that for oscillating move types it'd move from the starting point to one end and then get stuck in Waiting for Trigger. Firmware 9-70 fixes this. It also requires updating the C3ServoManager to 9-70 or higher as well.
*If the travel range is too short, the speed is not increased, as the drive does not reach the maximum speed.
