6 Installation Startup and Autotune Guides
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 pole
estimation 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".
The drive will then automatically populate the following parameters in the A1 and A5 menus:
• Enc Z-Pulse Offs (A5)
Inspection Run
Run the drive in low speed inspection mode and:
• Start with default values for INERTIA (A1).
• Ensure Motor Contactors are closing, Brake is lifting, and the car see that the car moves freely in the shaft.
• Verify encoder polarity. The motor phasing should match the encoder phasing. If you experience ENCODER FAULT/
HIT TRQ LIM alarm the phasing may be incorrect -the most likely cause is incorrect motor phasing. Swap two motor
phases, perform alignment and run again.
• Verify proper hoistway direction. If this is running with correct speed and control, but in the incorrect direction, swap
both Encoder Connect (C1) and Motor Rotation (C1), and repeat alignment procedure.
