690V: 504~720 V
Motor parameters are automatically set when performing an auto-tune (17-10=1). In most case no adjustment is
required after performing an auto-tune except when using the inverter in special applications (e.g. machine tool,
positioning, etc…).
Please refer to parameter group 22 for permanent magnet motor parameters.
(1) Number of motor poles (02-07)
Set the number of motor pole according to the motor nameplate.
(2) Motor rated power (02-05)
Set the motor power according to the motor nameplate.
(3) Motor rated current (02-01)
Set the motor rated current according to the motor nameplate.
(4) Motor rated voltage (02-04)
Set the motor rated voltage according to the motor nameplate.
(5) Rated frequency of motor 1 (02-06)
Set the motor rated frequency according to the motor nameplate.
(6) Rated rotation speed of motor 1 (02-03)
Set the motor rpm according to the motor nameplate.
(7) No-load motor voltage (02-19)
Parameter determines the rated flux during motor’s rated rotation in SLV or SV control mode. Set the value of this
parameter to the same value as parameter 17-08. A value of 10~50V below the input voltage level ensures that
the motor is capable of providing adequate torque performance when operating at nominal speed (or higher
speed). Setting the value to small can result in a reduction in no-load current, weakened motor flux and an
increase in motor current while the motor is loaded.
(8) Motor excitation current (02-09)
The current is obtained from rotational auto-tuning. It is required to perform manual tuning if the inverter cannot
rotational auto-tune.
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.
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.
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). 1
(9) Setting of motor core’s saturation coefficient 1, 2 and 3 (02-10, 02-11, 02-12)
