Motor rated current (02-01)
Set the motor rated current according to the motor nameplate.
(1)
The value of 02-01 needs to be greater than the value set in parameter 02-00, otherwise
warning message "SE01" out of range error will be displayed.
(2)
In V/F control mode, slip compensation function will be active whn output current is greater
than motor no load current.
(3)
In V / F control mode, the output current is greater than the no-load current with slip
compensation is enabled.
Rated rotation speed of motor 1 (02-03)
Set the motor rpm according to the motor nameplate.
Motor rated voltage (02-04)
Set the motor rated voltage according to the motor nameplate.
Set the motor rated voltage and it will adjust maximum output voltage of V/F curve.
Motor rated power (02-05)
Set the motor power according to the motor nameplate.
Rated frequency of motor 1 (02-06)
Set the motor rated frequency according to the motor nameplate.
Number of motor poles (02-07)
Set the number of motor pole according to the motor nameplate.
Motor excitation current (02-09)
(1)
The current is obtained from rotational auto-tuning. It is required to perform manual tuning if
the inverter cannot rotational auto-tune.
(2)
When the manual tuning is performed, tune it from 33% and observe no-load voltage (the
output value) of parameter 12-67. If parameter 12-67 is higher than no-load voltage (the
setting value) of parameter 17-08, perform downward revision in parameter 02-09; if it is lower
than that, perform upward revision in parameter 02-09.
(3)
Tuning motor excitation current of parameter 02-09 will change motor leakage inductance of
parameter 02-17 and motor mutual inductance of parameter 02-18.
(4)
It is required to refer to the actual no-load voltage of parameter 12-76 to tune the motor
excitation current of parameter 02-09. Change of the excitation current will also affect the
relative actual no-load voltage fluctuation so it is required to tune to the similar setting value of
no-load voltage (17-08).
Setting of motor core
’
s saturation coefficient 1, 2 and 3 (02-10, 02-11, 02-12)
These parameters are automatically set during auto-tune. No adjustment required. Parameters are
set to 50% for 02-10, 75% for 02-11 and 137.5% for 02-12 to reduce the impact of core saturation.
The motor core’s saturation coefficient is defined as a percentage of the motor excitation current.
When the motor flux reaches 137.5% level, the core’s saturation coefficient shall be greater than
137.5%. When the motor flux is 50% or 75%, the core’s saturation coefficient is required to be less
than 50% and 75%.
