6.3.3 Motor parameters setting
1) PAR_07(Motor rating setting) / PAR_08(Motor cap. selection of user)
Select the motor rating. Its factory default value is the same as inverter capacity. If this is set, motor parameters are
automatically set. These are designed to fit for LG-OTIS vector motor. When other makers ’ motor is used, program
the motor parameters properly. When using a motor having a rating not specified in this code, select “ User Define ” .
Then, PAR_08 will be displayed. Enter motor rating in this code. Then, enter motor parameters (PAR_17 ~ PAR_22) in
the name plate and perform Auto-tuning to gain proper parameters before use.

2) PAR_09 (Motor cooling method)
Select the cooling method of the motor to use. ‘ Motor cooling method ’ is used to check if the motor is currently
overloaded or not. The self-cooled motor should be set to ‘ Self-Cool ’ and the forced cooled motor to ‘ Forced-Cool ’ .

3) Encoder parameters (PAR_10 ~ 13: Pulse number of encoder, direction, error detection, LPF)
Enter the pulse number of encoder mounted on the motor shaft at the PAR_10 (the pulse number of encoder).
If PAR_12 ( Encoder error check enable) is set to ‘ Yes ’ , Encoder error signal is detected and then triggers fault alarm
in the case of the wire cut or the miswiring. But, for open collector type encoder, it is unable to detect the
encoder error, therefore PAR_12 should be set to ‘ No ’ . In case the wiring for encoder (A, B phase) or inverter
output (U, V, W) is changed, ‘ Enc AB Chgd ’ message is shown during the auto-tuning operation. In this case, PAR_11
(Enc Dir Set) can be changed without changing the wiring of pulse encoder. If encoder signal is mixed with
electromagnetic noise signal, encoder signal may be less affected by the electromagnetic noise signal by adjusting
PAR_13 ( Encoder LPF Time Constant) .
