6 Installation Startup and Autotune Guides
Open-Loop Startup
Open-Loop Operation Set-up
Enter / verify that the drive is set to run in Open Loop Vector in the Drive Mode menu (U8).
Hoistway Parameter Set-up
Enter / verify the hoistway parameters:
• CONTRACT CAR SPD (A1) parameter should be the elevator contract speed in m/s.
• CONTRACT MTR SPD (A1) parameter should be set to an RPM that will make the elevator travel at desired car speed
(measured with hand tachometer).
Note: The above two parameters are utilized by the drive for many purposes regarding speed control of the lift, therefore it is important
these are set correctly.
Input Voltage
Enter the Line Voltage in the A4 menu:
• INPUT VOLTAGE (A4) parameter should be set to the measured incoming phase to phase voltage.
Autotune
The autotune can now be performed by navigating to the U9 menu. The drive has several options for autotuning the
motor, however usually the motor will be roped, and so the ‘Tune-No Rotate1’ (Static) method will be used.
If the ropes are off, and the motor can turn freely, the ‘Standard Tune’ (Rotating) method can be used.
Navigate to the U9 menu and enter the following information:
• ‘Tune-No Rotate1’ (TUNING MODE SEL(U9))
• Rated Motor Power in kW (MTR RATED POWER(U9))
• Rated Motor Voltage in V (RATED VOLTS(U9))
• Rated Motor Current in A (RATED CURRENT(U9))
• Rated Motor Frequency in Hz (RATED FREQUENCY (U9))
• Number of Motor Poles (NUMBER OF POLES(U9))
• Rated Motor Speed*. This is after slip, so NOT synchronous speed. (RATED SPEED (U9))
• Encoder Pulses (PG PULSE/REV (U9))
• No Load Current. If this is not stamped on the motor, leave it as the default value (NO-LOAD CURRENT(U9))
*Note: The rated motor rpm must be full load speed. If synchronous speed is given, the motor rated rpm can be estimated by:
– 97.5% of synchronous speed for Nema type B motor design
– 94% of synchronous speed for Nema type D motor design
Table 17 Synchronous/Asynchronous Motor Speeds and Motor Poles Reference for 50Hz
Once the above information has been input, the bottom of the menu will be reached, and the screen will display ‘Begin
Autotune?’. You can then give and maintain a test/inspection run in the up direction, and the drive will perform the
autotune as long as the run command is issued. If the drive has control of the motor contactors they will now pull in and
the tune will begin.
During this process the drive will display motor speed and motor current for reference.
Once complete the drive will display “END Tune Successful”.
Synchronous Speed Rated Motor Speed (rpm) Number of Motor Poles

1000 998 - 797 6
750 748 - 598 8
600 599 - 478 10
