Please see H50 to H54 for more detail.
[SVC]: Use sensorless vector control when 1) high starting torque is
required at low speeds 2) the load fluctuates 3) fast torque response times
are needed.
For proper operation, set H42-H46.
Set “Yes” in H41 [Auto tuning] first before using this control.
H41: Auto Tuning
Range: 0 - 1 (Default: 0)
Description: All of the motor parameters can be tuned by setting “YES (1)”. Auto tuning
is deactivated when “No (0)” is selected.
The auto tuning function automatically measures the motor parameters
needed for the control selected in H40 [Control mode] such as stator
resistance, rotor resistance, leakage inductance, no-load current and Encoder
feedback frequency.
z Note: The rated current, voltage, efficiency and slip described in the
motor nameplate should be entered before performing auto tuning. The load
should not be connected when performing an auto tune in H41.. If efficiency
is not indicated on the nameplate, use the default value.
H42: Stator Resistance (Rs)
Range: 0-14W
Description: This is the value of the motor stator resistance.
