10.5. Step 5- Motor Auto-tune.
A Motor Auto-tune must be carried out in order to measure the motor electrical characteristics, brakes will be applied by the drive (unless
controlled by other means) during this test.
Action
 If the motor contactor(s) are controlled by the elevator controller then they should be activated to close so that the motor is electrically
connected to the drive, otherwise the "Auto-tune" cannot be carried out.
 If the motor contactor(s) are controlled by the drive (connected to relay 1) the motor contactor will automatically be energised when the
"Auto-tune" is enabled.
 Check Safe Torque

Enter Current value as shown on the motor nameplate (Amps).
Enter Frequency value as shown on the motor nameplate (Hz).
Enter motor pole value as shown on the motor nameplate, if unknown set P4-05 to 0
where the drive will automatically calculate the value providing P4-04 (Motor rated
frequency) and P4-06 (Motor rated speed) have been entered correctly.
Enter motor rated speed value as shown on the motor nameplate (rpm).
The drive display will now show motor speed in estimated rpm. All speed related
parameters, such as Minimum and Maximum Speed, run Speeds etc. will also be
displayed in Rpm.

Obtained from Motor nameplate.
•
If Motor power factor is unknown leave as default value.
Note: When the motor is running, parameter P0-22 displays the measured power factor
value, and this can then be entered into P4-07.
This is the maximum allowable speed in rpm.
Set P4-08 to a 1
