Chapter 5 Detailed Function Introductions
The parameters setting of motor 2. The detailer settings are the same as motor 1. The settings are valid after the
PA.00 is set to 2.
PA.29 Motor parameter setting
0: No operation
2: Rotation parameter setting
Notes
No operation
1: static parameter setting; it is applicable on occasions where a motor and load cannot be disconnected easily
and rotary setting is disabled. When the function code is set and able to RUN, the frequency converter will set
the function form PA.06~PA.08 / PA.20~PA.22 automatically.
PA.05, PA.09 / PA.19 and PA.23 should be set manually according to the standard motor parameters.
2: Rotary parameter setting; to ensure the dynamic control performance of frequency converter, please select
the rotary parameter setting. At setting, the motor should be disconnected from the load (no load). When the
function code is set and is able to RUN, it means that automatic setting is enabled.
Tips:
1.
Before the parameters setting, please enter the correct nameplate parameter of the controlled motor
(PA.01 ~ PA.04 PA.15 ~ PA.18).
2.
When rotation setting, you should let the motor off from the load. It is banned that setting with the load.
3.
Before parameter setting, please confirm the motor is in stoppingstopping state. Otherwise, it cannot be
normal.
4.
After the parameter setting process is completed (including abnormal end) , it is automatically set to 0.
5. During the process of parameter setting, the operation panel will display "- At-". If the parameter setting is
unsuccessful, the operation panel will display "AtE".
Notes:
At the time of static setting, the motor no-load current calculation method and the motor mutual inductance
calculation method are showed in the following formulae. Among them, L is the motor leakage inductance,
L
the no-load current,
m
the rating voltage of motor, and f is the fundamental frequency of motor.
The specific meanings of the above motor parameters are showed in Figure 5-10-1.
