c
Speed Loop Setting
Set the speed loop gain and integral time constant.
If the response of the speed loop is poor, the moment of inertia (mass) ratio cannot be measured accu-
rately.
The speed loop setting to get the required response for the moment of inertia (mass) setting is already
set to the default setting. Normally, this setting does not have to be changed.
If this speed loop gain is too high, and is causing excitation in the machine, lower the setting.
d
Identification Start Level
Set the moment of inertia (mass) identification start level.
With a heavy load or low-rigidity machine, torque limit may be applied and the moment of inertia iden-
tification may fail.
In this case, double the identification start level and execute identification again.
