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.
