6.6.4 Inertia mode and related parameters
The adaptive default parameter is defined as small inertia mode. If the load inertia far exceeds the
allowable load inertia of the motor (such as 60 times inertia of the 60 motor), the adaptive large inertia
mode can be turned on.

Note 1: DS5 series servo 750W and below driver default value is 400; other power section default
value is 200.
Note 2: DS5 series servo 400W and below driver default value is 70; other power section default value
is 50.
6.6.5 Recommended inertia ratio parameters
Under the adaptive default parameters, the load can only run steadily under a certain moment of inertia.
If the load inertia is large, some parameters need to be adjusted. The recommended parameters are as
follows (the parameters are modified under the default parameters).

Parameters
40~90
Within 20 times inertia
Adaptive small inertia mode (default parameters)
20-30 times inertia
Set P2-08=50, P2-12=40
30-40 times inertia
Set P2-08=50, P2-12=40, P2-07=10
40-50 times inertia
Set P2-08=50, P2-12=40, P2-07=30
50-80 times inertia
Switch to adaptive large inertia mode or set P2-08=40,
P2-12=50, P2-07=50
Note: The large inertia parameters can still drive a smaller inertia load. For example, when the
parameters of 50 times inertia are used in the mechanism of 20 times inertia, only the response will
become worse.
