The increase will slightly improve the
inertia capacity of the belt and has little
impact on the responsiveness. It is used as
an auxiliary parameter
(1) P2-19 different power drivers have different default values.
(2) The default value of P2-05 in drives of 1.5KW and above is 200.

If the load inertia exceeds the recommended value in the table, the gain related parameters need to be modified
as follows:
1. If the inertia is about 20 to 30 times
Appropriately increase P2-07 and reduce P2-05 if necessary; You can also refer to the following super inertia
commissioning method.
2. Commissioning experience of super large inertia (50 ~ 100 times inertia)
Increase P2-12 (40 ~ 50 recommended), decrease P2-08 (40 ~ 50 recommended), decrease P2-05 (100 ~ 300
recommended), and increase P2-07 (10 ~ 100 recommended) to adjust flexibly according to the load inertia.
