suitable for the unit.
Note 6) Power supply capacit y
Make sure that capacit y of the tr ansformer used as the inverter' s power supply is within the
following range. ( For 4% impedance transform er)
Constant torque: 500kVA or less
Variable torque: Capacity that is 10-times or less inverter capacity
If the above values are exc eeded, install an AC Reactor on the inv erter ' s i nput side or a DC
Reactor in the DC stage. ( Refer to chapter 7-5).
Note 7) Noise measures
The inverter will generate high harmonic electrom agnetic noise, so using the following noise
measures is recomm ended. This must be followed for EMC (CE compliance)
a) I nsert a noise filter on the input side of the inver ter. Refer to Table 7-2 and select t he noise
filter.
b) Keep the wiring length bet ween the noise filter and inverter to 30cm or less f or the N00K4 to
N22K0, X00K4 to X30K0, and 50cm or less f or the N30K0 to N37K0, X37K0 to X45K0.
c) Use a shield cabl e for the inverter and motor wiring, and connec t the screen to the inverter ' s
terminal and motor gr ounding terminal.
d) When both control circuit wir ing and main circuit are wired in parallel, keep distance of 30cm
or more, or pass each of the wiring through metal conduits. If the c ontrol c ir c uit wiring and
main circuit wiring intersect, make sure that they intersect at a right angle.
Note 8) Inverter output
a) Do not insert a power factor improvement capacitor on the output side of the inv er ter.
b) When inserting a magnetic c ontactor on the output side of the invert er , prepar e a sequence
control circuit so that the magnetic contactor will open and c lose after the invert er stops.
Note 9) G r ounding
Always wire the inverter’s ground terminal. T he gr ound m ust be according to the regulations of
the Country where the i nv erter is bei ng used .
Note 10) Inverter outpu t surg e vol t age (Fo r 400V Seri es)
The surge voltage applied on the motor side increases depending the output cable lengt h, If this
wiring between mot or and drive exceeds in 30mts, connect a surge absorber exc lusive for the
inverter output .
Note 11) DCL
Always short cir c uit acr oss L+1 and L+ 2 when not using the DCL. (Factory setting stat e)

1) Preparation
Separate the mot or and l oad, mac hine, etc., and confirm the safety on the load side.
2) Selection of control method
• Set A05-2 to 1. (enables parameter display)
• By par am eter (C30-0), select V/f control according the load conditions
IM speed sensor-less vec tor control (C30-0 = 3), ( Default value)
IM vector control with speed sensor (C30-0 = 4)
* The default value is V/f control ( c onstant torque) (C30-0 = 1).
3) Initialisation of motor constants
Input the motor rating nameplate value parameters. Automatic tuning will automatically change the
parameters, so it is re co mmended to write down the values se t in tab le 3-6-4 or table 3-6-5.

* When the motor works under constant power operat ion, the excitation induct ance fluctuation
must be compensated.
Assign the operation r ange to the table reference speed in B 33- 0 to 7.
Note that the motor will rotate to the max. speed in this case, so take special c ar e to safety.
* The max. speed cannot be set below the base speed, and the base speed cannot be set
above the max. speed.
(Note 1)
During IM speed sensor-less vector control (C30-0 = 3), it is recommended to set the
carrier frequency to 10KHz to improve the current detection accuracy.
(Note 2)
Always enter encoder pulse numbers when using the speed sensor.
4) Selection of automatic tuning function
• Set A05-0 to 1. (enables parameter display)
• By par am eter (B19-0), select the automatic tuning mode according working conditions. Ref er to
section 3-6-1 for details.
• T he automatic tuning will star when the
key is pressed.
• During the automatic t uning state, the LCL LED will blink.
• T o abor t the automatic tuning standby state, press the
key.

5) Starting automatic tuning
Automatic tuni ng will start when the
key or key is pressed according t o the required
rotation dir ection. A message indicating star ting will appear on the operation panel.
To stop, press the
key or input the emergency stop signal (EMS) from the terminal block.
* Keys other than
and are disabled during automatic tuning.
6) Duri ng automatic tuning execution
The progression state can be conf irmed with D22-0.
Refer to section 3-6-4 for details.
7) Normal completion of automatic tuning
The "LCL" LED will end blinki ng, lighting stable, and a message indic ating the end will be
displayed. Ref er to section 3-6-2 for the adjustment items.
8) Abnormal completion of automatic tuning
If the automatic tuning ends abnormally , a message will appear. Investigate and check according
to the error codes. Refer to section 3-6-3 for detail s on the error c odes.
9) Additional settings and adjustments
There are some parameter r elated to load condition or requir ed r esponse control which shoul d be
adjusted manually. The main parameters are shown below.
• A10- 0: ASR response : Set the speed control response in [r ad/s] unit.
If the speed tracki ng is slow, i nc r ease this value.
Note that if this val ue is too high, hunting may occur.
• A10- 1: Machine time constant 1 : Set the time required t o accelerate from zero to the base
speed with the rated torque.

• A10- 2: Integral tim e constant c om pensation coefficient:

• A10- 3: ASR drive torque limit : Increase if a higher driv e torque is required.
• A10- 4: ASR regenerative torque lim it : Increase if a higher r egener ative torque is
required.
9) Adjustment for Induction Motor, sensorless vector control
Adjust the following items, to improve accuracy
•
Fine adjustment of primary resistance
With motor unloaded, run the motor at the minimum speed to be used, and finely adjust the
primary resistance (B02-0,1). For Forward run, adjust so that D11-4 (ASR output) is near zero
on the positiv e side. ( Note that B02-0 can be set during run but B20-1 can not)
Make sure that the D11-4 does not reach t he negative side during forward run.
•
Adjustm e nt of es t im a t e d s pe e d integral gain
Confirm that D00-3 (motor speed on % units) is stable (±1% or less) during trial operation. If not
decrease (approx. half) the speed estimated pr opor tional gain (B31-1)
