TECO A510s - PM SLV Start Current; I;F Mode Start Frequency Switching Point; Armature Resistance of PM Motor

4-310
22-08: PM Encoder Type
After PM encoder type is adjusted, the inverter is required to reconnect to renew the system.
If user does not need the specified encoder types, select item 3 to avoid the error. When item 3 is selected, run
start is the strong magnetic start and the current is about 80% setting value of the rated current (22-02) at start.
Sine Wave card is for Heidenhain ERN 1387 and ECN 1313
22-10: PM SLV Start Current
Set torque current at start and the unit is the percentage of motor rated current.
22-11: I/F Mode Start Frequency Switching Point
This function is for the switching point from open-loop to close-loop in PMSLV mode. The unit is percentage for
rated speed of motor .It recommends that over 5% for 400V and over 10% for 200V.
22-12: KP Value of Speed Estimation; 22-13: KI Value of Speed Estimation
It is used for adjusting speed response performance. The higher the setting value is, the faster the
motor response is. But the higher setting value will cause the controlled object to oscillate and unstable.
If the setting value is lower, speed deviation range will be larger. So adjust appropriate setting value in
accordance with the field devices.
22-14: Armature Resistance of PM Motor
Set resistor for each phase of the motor in unit of 0.001Ω. It is set automatically when the motor auto-tunes
(22-21).
Note: Do not be confused with line-to-line resistance.
22-15: D-axis Inductance of PM Motor
Set motor’s D-axis inductance in unit of 0.001mH. It is set automatically when the motor auto-tunes (22-21).
22-16: Q-axis Inductance of PM Motor
Set motor’s Q-axis Inductance in unit of 0.001mH. It is set automatically when the motor auto-tunes (22-21).
22-18: Flux-Weakening Limit
If the motor’s maximum rotation speed (22-05) is set to be higher than the motor’s rated rotation speed (22-04), it
will automatically start the flux-weakening control. It is set to limit the maximum flux-weakening energy and the
unit is the percentage of motor rated current.
22-20: Offset Angle of the Magnetic Pole and PG Origin
Magnetic pole alignment offset value is stored in this parameter after tuning.
22-21: PM Motor Tuning
WARNING!
Sudden start: The inverter and motor may start unexpectedly during Auto-Tuning, which could result in death or
serious injury. Make sure the area surrounding of the motor and load are clear before proceeding with
Auto-Tuning.
