48 SUNFAR C300
C300 series of non-sensor current vector-control inverter manual
The inverter will modify output freq. automatically to offset effects that is acting on
rotational speed of motor form
Those parameters are nameplate data of applied motor. And they need input one
by one according to capacity of applied motor, when inverter takes vector method.
Generally, exciting current of applied motor needn’t modify. Because it will
automatically update when rated current of applied motor is modified.
0： It will be invalid.
1： Determine parameters when motor stops
2： Determine parameters when motor runs（Reserved）
Both vector control method
（[F0.0] = 1）and panel control method（[F0.4] = 00#0）are
valid.
When parameter F1.20 is valid, inverter will determine parameters by press .
Parameters will save automatically in inverter’s memory and Parameter F1.20 will
clear automatically.
Before start function of Parameters self-determination, please make sure that
nameplate parameters of motor
（[F1.15] ~ [F1.18]）are input correctly and the motor
has stopped.
Self-determination function of static parameter: motor would always keep silent
when parameter is self-determining.
Self-determination function of dynamic parameter: motor runs to rated speed for a
while then stop automatically in the process of self-determining. Make sure that
