Description
Control performance optimized for cyclic load
applications.
This setting is to be used by ABB-authorized service
personnel only.
Enables 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.
Signal injection disabled.
Signal injection enabled with an amplitude level of 5%.
Signal injection enabled with an amplitude level of 10%.
Signal injection enabled with an amplitude level of 15%.
Signal injection enabled with an amplitude level of 20%.
Rotor 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.
Rotor time constant tuning.
Selects 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
