5.11 Auto-Tuning

5.11 Auto-Tuning

Auto-Tuning automatically sets and tunes parameters required for motor operation.

Types of Auto-Tuning

u
There are three types of Auto-Tuning.
Type
Rotational Auto-Tuning for V/
f Control
Rotational Auto-Tuning for
OLV Control
Stationary Auto-Tuning for V/
f and OLV Control Line-to-
Line Resistance Only
Note: Auto-Tuning cannot be performed on permanent magnet motors (IPM, SPM, etc.).
