Autotuning Control (Group P1); Inertia Identifying (Or Automatic Gain) - INVT DA180-S2R8SG0 Operation Manual

DA180 series basic AC servo drive

6.2 Autotuning control (group P1)

6.2.1 Inertia identifying (or automatic gain)

P1.00 Tune inertia online
This parameter specifies whether to automatically tune inertia online and adjust the gain.
Setting

Data size
P1.00
Modbus address
P1.01 Inertia ratio 1
Rotation inertia ratio = Load inertia/Motor rotation inertia x 100%
If P1.01 is set correctly, the setting unit of P2.00 and P2.05 is Hz.
If P1.01 is greater than the actual value, the speed loop gain unit will increase, and if it is smaller
than the actual value, the speed loop gain unit will decrease.
If online automatic tuning is valid, the inertia ratio is updated to P1.01 in real time and written to the
EEPROM every 30 minutes.

P1.02 Inertia ratio 2
The meaning of P1.02 is similar to that of P1.01.
Note: Automatic online gain adjusting is invalid for this parameter.
