Chapter 12 Description of Parameter SettingsC2000
If the value does not change (inertia
estimation error), decrease the
frequency command, and re-estimate
the inertia
Continue forward/backward running,
so the inertia estimation can
converge to small changing
differences.
 Basic Motor Parameters Adjustment
1. Parameter reset:
Pr.00-02=9 (50Hz) or 10 (60Hz), reset parameter to the default value.
2. Select IPM motor type:
Pr.05-33=1 (SPM) or 2 (IPM)
3. Motor nameplate parameter setting:
Parameter
Pr.01-01
Pr.01-02
Pr.05-33
Pr.05-34
7.Re-power after Power Off
8.PM Motor Inertia Estimation
1) Pr.00-11=4 FOCPG control
2) Set the running frequency to 2/3 of the motor rated
frequency.
3) Set the accel./decel. time as 1/10 of the default value.
(Adjust the accel./decel time based on the load inertia.
The smaller the inertia is, the shorter the accel./decel.
time will be)
4) Check connection of the load and the motor
5) Pr.11-00=bit1=1 inertia estimation（for FOCPG mode）
Rapid forward/reverse run repeatedly

Trial Run
Different load inertia will have
different converging speed. The
larger the intertia is, the slower
it will converge. Which needs to
estimate for several times.
