Function Parameters
AC10 Inverter
6 (Synchronous motor control mode)
When F106=6, default values of frequency source can not be adjusted automatically.
When F106=6, independent DC brake function is adopted. And F602 and F603
change to percentage of the PMSM rated current;(Default value = 10%)
F800: auto tuning of motor’s parameter, F800=0, No parameter measurement,
input the parameters of PMSM from F870 to F873 by hand. F800=1/2, running
parameter measurement / static parameter measurement.
The running command is given by keypad panel or terminals, then the keypad panel
will display "TEST" till parameter measurement is over. The parameters of PMSM will
be stored in function codes from F870 to F873 automatically.
F800=1, running parameter measurement. In order to ensure dynamic control
performance of the inverter, select “running motor parameter measurement” after
ensuring that the motor is disconnected from the load. At the last stage of parameter
measurement, motor will run at the first or second accel/decel time.
F800=2, Static parameter measurement. It is suitable for the cases where it is
impossible to disconnect the motor from the load. In this process, the value of F870 is
a theoretical value. We suggest you that you can get the exact back electromotive
force value from the manufacture of the motor.
F804 The number of motor poles is automatically generated according to the motor
rated speed and rated frequency, it cannot be set.
Note: after setting the motor parameters, please check the motor number of poles
carefully. If it is different with actual value, when input the value of F810 according to
motor nameplate, add one in the first digit after the decimal and change the second
digit after the decimal to 0.

F870(back electromotive force of PMSM
，
unit = 0.1mV/1rpm, it is back electromotive
force value between lines);
∈
[0.1, 999.9] mV/rpm, it is forbidden to revert to Mfr’s
value by F160.
F871(PMSM D-axis inductance
，
unit = 0.01 mH);
∈
[0.01, 655.35]mH, it is forbidden to
revert to Mfr’s value by F160.
F872(PMSM Q-axis inductance
，
unit = 0.01 mH);
∈
[0.01, 655.35]mH, it is forbidden
to revert to Mfr’s value by F160.
F873(PMSM Stator resistance
，
unit = m-ohm
，
0.001 ohm);
∈
[0.001, 65.535]ohm, it
is forbidden to revert to Mfr’s value by F160.
F876(PM Injection current compensation without load
，
unit = 0.1%);
∈
[0.0, 100.0] the
default value is 20.0%, it can be reverted to Mfr’s value by F160;
F877(PM Injection current compensation without load
，
unit = 0.1%);
∈
[0.0, 50.0] the
default value is 0.0%
，
it can be reverted to Mfr’s value by F160.
F878(PM Cut-off point of injection current compensation without load
，
unit = 0.1%);
∈
[0.0, 50.0] the default value is 10.0%
，
it can be reverted to Mfr’s value by F160;
Caution
：
take an note of the value of F876, F877 and F878:
When F876=20%
，
if F877=10%
，
F878=0%
，
then the value of injection current without
load is always 20(F876)
Example: F876=20% (of rated current)
，
F877=10% (of rated current), F878=10% (of rated
frequency)
–
Rated frequency =50Hz, rated current=10A:
The drive starts at 0 Hz with a no-load current of 3A (20%+10% of 10A), the no-load current
decreases linearly to 2A (20%) until the drive reaches the cut-off point of 5 Hz (10%of 50Hz),
remaining constant for all frequency above 5 Hz.
F880(PM PCE detection time
，
unit = 0.1s);
∈
[0, 10.0]S the default value is 0.2S, it can
be reverted to Mfr’s value by F160.
