➢ If the presumed inertia under default parameters runs jitter, indicating that the present load inertia is too
large, please switch to large inertia mode (P2-03.3=1) and operate again. It is also possible to set the
initial inertia to about twice the current one and execute again under larger loads.
➢ Driver inertia ratio recognition upper limit is 200 times (parameter upper limit is 20000). If the
estimated inertia ratio is exactly 20000, it means that the inertia ratio has reached the upper limit and
can not be used, please replace the motor with larger rotor inertia.
Other notes
➢ At present, the inertia switching function is not supported, and the second inertia ratio is invalid.
➢ The inertia ratio upper limit changes to 500 times for the driver firmware 3700 and higher version
(parameter upper limit value is 50000).
5.2.3 Operation tool
The presumptive tools of load moment of inertia are driver panel and XinjeServo software.
Note: driver firmware version can be checked through U2-07.
5.2.4 Operation steps
1. Click auto-tuning on the main interface of XinJeServo
