Note: W hen using a PM m otor for the first tim e, or when replacing the drive or PM motor, always make sure that m otor param eters are
set properly and the speed detection functions accurately prior to operation. U sing a PM m otor requires that the encoder offset be
set correctly in addition to entering m otor data to corresponding parameters. I f the motor, encoder, or drive are ever replaced, be
sure to perform Encoder Offset Auto-Tuning.
Insufficient torque can cause the elevator car to move in the direction o f the load, or cause the motor to behave erratically
(reverse operation, stand still, sudden accelerations, etc.).
For more information, refer to the instruction manual included with the motor.
♦ Types of Auto-Tuning
The drive offers different types of Auto-Tuning for induction motors and permanent magnet motors. The type o f Auto­
Tuning used differs further based on the control mode and other operating conditions. Refer to the tables below to select
the type o f Auto-Tuning that bests suits the application. Directions for performing Auto-Tuning are listed in Start-Up
Flowcharts on page 88.
Note: The drive will only show A uto-Tuning param eters that are valid for the control mode that has been set in A1-02. I f the control
mode is for an induction motor, the A uto-Tuning param eters for PM motors will not be available. I f the control mode is for a PM
motor, the Auto-Tuning parameters for induction m otors will not be available. Inertia Tuning and A SR G ain Tuning parameters
and setting options will be visible only when the drive is set for operation w ith CLV or CLV/PM.
■ Auto-Tuning for Induction Motors
This feature automatically sets the V /f pattern and motor parameters Б 1-П П and Б 2-П П for an induction motor.
Additionally, the feature also sets some F1-D D parameters for speed feedback detection in Closed Loop Vector.

• Rotational Auto-Tuning gives the m ost accurate results, and is recommended if possible.
• Motor must run freely or with light load (<30%), i.e. ropes have to be removed.

• U sed for V /f Control or in vector control modes when the drive was previously set up properly and now
the motor cable has changed.
• U sed in V /f control i f drive and motor capacities differ.
• Should not be used for any vector control modes unless the motor cable has changed.

• A motor test report is available. Once the no-load current and the rated slip have been entered, the drive
calculates and sets all other motor-related parameters.
• U se i f ropes can not be removed and i f slip and no-load current data are available.
No Yes Yes
Table 4.6 lists the data that must be entered for Auto-Tuning. Make sure this data is available before starting Auto­
Tuning. The necessary information is usually listed on the motor nameplate or in the motor test report provided by the
motor manufacturer. Also refer to
