6.2.4.2 Running a rotating auto-tuning for induction motors
Preparation
Before running a rotating auto-tuning, disconnect and remove the machinery
that is connected to the motor axis, and leave the motor unloaded. Unintended
operation of the machinery during tuning may lead to personal injury and/or
mechanical damage. A braking resistor must be connected to the inverter
when running an auto-tuning. Abrupt accelerations and decelerations are
required to find an optimal rotor time constant.
