WARNING!
Sudden Movement Hazard. Do not release the mechanical brake during Stationary Auto-Tuning. Ensure that the
mechanical brake release circuit is not controlled by the drive multi-function digital outputs exclusively. Failure to comply can
result in death or serious injury.
•
Rotational Auto-Tuning is the preferred tuning method because it gives more accurate results than Stationary
Auto-Tuning. Perform Rotational Auto-Tuning when the motor can be uncoupled from the elevator mechanical
system (remove ropes from traction sheave). Perform Stationary Auto-Tuning when the motor and mechanical
system cannot be uncoupled.
•
Make sure that the mechanical brake remains applied for all Stationary Auto-Tuning methods. Make sure to
release the brake for all Rotational Auto-Tuning methods.
•
When using a motor contactor, make sure it is closed throughout the Auto-Tuning process.
•
The H1 signal must be ON when performing Auto-Tuning.
•
A digital input programmed for Baseblock (H1-xx = 8 or 9) must be set so that the drive is not in a baseblock
condition.
•
Confirm that the motor is mechanically fixed.
•
To cancel Auto-Tuning, press the STOP key on the digital operator.
•
Auto-Tuning requires the user to input data from the motor nameplate or motor test report. Make sure this data
is available before Auto-Tuning the drive.
•
For best performance, the drive input supply voltage must be greater than the motor rated voltage.
Improved performance is possible when using a motor with a base voltage that is 40 V lower than the input supply
voltage. This is particularly important when operating the motor above 90% of base speed, where high torque
precision is required.
WARNING!
Sudden Movement Hazard. Stay clear of the motor during rotational auto-tuning. During automatic starting of
equipment, the machine may start moving suddenly. Clear all personnel from the drive, motor, and machine area before
applying power. Secure covers, couplings, shaft keys, and machine loads before applying power to the drive. Failure to comply
can result in death or serious injury.
The following table describes digital input and output terminal operation while Auto-Tuning is executed.

Auto-Tuning Interruption and Fault Codes
If tuning results are abnormal or the STOP key is pressed before completion, Auto-Tuning will be interrupted and
a fault code will appear on the LED operator.
◆
Auto-Tuning Operation Example
The following example demonstrates Rotational Auto-Tuning when using
OLV [A1-02 = 2]
.
1.
Turn on the power to the drive.
The initial display appears.
2.
Press
or
until the Auto-Tuning display appears.
3.
Press
to start setting parameters.
4.
Press
to display the value for T1-01.
5.
Press
to select the digit to be modified.
6.
Press
to select Rotational Auto-Tuning.
7.
Press
to save the setting.
The display returns to the display shown in step 3.
