incorrect motor data calculation. Disconnect the motor and the load and confirm that the motor can freely
run.
1. Before selecting PM motor tuning, enter the motor data (22-00) - (22-06) according to the motor
nameplate.
2.
a) Use parameter 22-21 to select tuning mode.
b) Next press the enter key to go to the PM motor tuning screen. The keypad will display the
message of "IPrdy" (Ready to Tune).
c) Press run to start the PM motor tuning. The keypad will display the “IPtun" message during
auto-tune.
d) If the motor is successfully tuned, the message of "IPEnd " will be displayed. If auto-tune is
aborted with the stop key, the operator will display the message of " IPbrd " (PM motor tuning
aborted).
Notes:
1. Perform a magnetic pole alignment auto-tune before adjusting the speed loop.
2. It is not required to perform a magnetic pole alignment auto-tune each time the inverter is powered up.
Fault History of SLV PM Motor Tuning (22-22)
If PM motor tuning has failed, the “IPErr” message is shown on the keypad (PM motor tuning failure). Refer
to section 10 for the possible error causes and trouble shooting.
PM motor tuning fault history (22-22) only stores the result of the last auto-tune performed .If auto-tuning
was successful or aborted, no error will be displayed.
Detection Mode Selection of Default Magnetic Pole (22-25)
Select the motor activation’s rotor position detection method
Method 0: Do not detect rotor position, start by directly using the angle when the motor was previously
stopped
Method 1: Use input pulse signal to detect rotor position.
Method 2: Use input continuous variable frequency signal to detect rotor position.
Selection of rotor position detection mode when the motor starts:
22-25=0: Angle before Stop
The rotor position is not detected and the motor starts by the angle before Stop
22-25=1: Mode 1
Pulse input signals detect the rotor position and there is jitter in the detection process.
22-25=2, Mode 2
Input continuously variable frequency signals to detect the rotor position.
