. Set the number of motor pole as written on motor nameplate.
(2) Motor rated power (02-05)
. Set the power value on motor nameplate.
(3) Motor rated current (02-01)
. Set the full-load current on motor nameplate.
(4) Motor rated voltage (02-04)
Set the rated voltage on motor nameplate.
(5) Rated frequency of motor 1 (02-06)
Set the frequency on motor nameplate.
(6) Rated rotation speed of motor 1 (02-03)
Set the rotation speed on motor nameplate.
(7) Voltage of motor without load (02-19)
. if parameters 17-08 or 02-19 have been set, this parameter is the same as that of
17-08. This parameter determines the rated flux at motor’s rated rotation in SLV or
SV control mode. Settings below input voltage of 10~50V can ensure that the
motor is capable of providing torque performance when the motor operates at rated
rotation speed (or higher speed).
. The smaller voltage without load can reduce the current without load, weaken flux
and increase current with load; while larger voltage without load is opposite.
(8) Motor excitation current (02-09)
This parameter is automatically set by the auto-tuning function. In general, no need
to tune it.
(9) Setting of motor core’s saturation coefficient 1,2 and3 (02-10,02-11,02-12)
. This parameter is automatically set by the auto-tuning function. In general, no
need to tune it.
. This parameter sets 50% (02-10),75% (02-11),137.5%(02-12) of motor core’s
saturation coefficient in order to reduce the impact from core saturation.
. Motor core’s saturation coefficient is the percentage of the motor excitation current.
When the flux reaches 137.5% level, the core’s saturation coefficient shall greater
than 137.5%. when the flux is 50% or 75%, the core’s saturation coefficient is
required to less than 50% and 75%。
(10) Motor core’s loss setting(02-13)
. Set motor core loss as the percentage of the rated output power of motor.
3 × motor core loss (watt)
Rated output power of motor (watt , 02-05)
. in V/F control mode，the setting of motor core loss (02-13) is used to compensate
the torque accuracy.
(11) Resistence R1between wires of motor (02-15).
(12) Leakage inductance of motor Llkg (02-17).
(13) Mutual inductance of motor Lm (02-18).
(14) Motor rotor’s equivalent resistance R2 (02-16).
(15) Current of motor without load (02-00).
. This set value is calculated according to the motro rated frequency (17-05) and
the motor rated
current (17-03)
. In V / F control mode, the output current is greater than the motor current without
load, slip
compensation is enabled.
. 02-01must be greater than 02-00，otherwise a warning message "SE01" of range
error will be
displayed.
. Refer to Y-equivalent model of the induction motor shown in Figure 4.3.15.
