Disabled / uint16Enables signal injection. A high-frequency alternating
signal is injected into the motor at low speeds to
improve the stability of torque control. Signal injection
can be enabled with different amplitude levels.
Note: This is an expert level parameter and should not
be adjusted without appropriate skill.
Note: Use as low a level as possible that gives
satisfactory performance.
Note: Signal injection cannot be applied to
asynchronous motors.

100 % / real32Rotor time constant tuning.
This parameter can be used to improve torque accuracy
in closed-loop control of an induction motor. Normally,
the motor identification run provides sufficient torque
accuracy, but manual fine-tuning can be applied in
exceptionally demanding applications to achieve
optimal performance.
Note: This is an expert level parameter and should not
be adjusted without appropriate skill.

Disabled / uint16Selects whether the temperature-dependent
parameters (such as stator or rotor resistance) of the
motor model adapt to actual (measured or estimated)
temperature or not.
See parameter group 35 Motor thermal protection for
selection of temperature measurement sources.
