If the above values are exceeded, install an AC Reactor on the inverter's input side or a DC
Reactor in the DC stage. (Refer to chapter 7-5).
Note 7) Noise measures
The inverter will generate high harmonic electromagnetic noise, so using the following noise
measures is recommended. This must be followed for EMC (CE compliance)
a) Insert a noise filter on the input side of the inverter. Refer to Table 7-2 and select the noise
filter.
b) Keep the wiring length between the noise filter and inverter to 30cm or less for the N00K4 to
N22K0, X00K4 to X30K0, and 50cm or less for the N30K0 to N37K0, X37K0 to X45K0.
c) Use a shield cable for the inverter and motor wiring, and connect the screen to the inverter's
terminal and motor grounding terminal.
d) When both control circuit wiring and main circuit are wired in parallel, keep distance of 30cm
or more, or pass each of the wiring through metal conduits. If the control circuit 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 inverter.
b) When inserting a magnetic contactor on the output side of the inverter, prepare a sequence
control circuit so that the magnetic contactor will open and close after the inverter stops.
Note 9) Grounding
Always wire the inverter’s ground terminal. The ground must be according to the regulations of
the Country where the inverter is being used .
Note 10) Inverter output surge voltage (For 400V Series)
The surge voltage applied on the motor side increases depending the output cable length, If this
wiring between motor and drive exceeds in 30mts, connect a surge absorber exclusive for the
inverter output.
Note 11) DCL
Always short circuit across L+1 and L+2 when not using the DCL. (Factory setting state)
When connecting the optional DCL, connect it to L+1 and L+2.
Twist the wiring to the DCL, and keep the wiring length to 5m or less.
Note 12) DBR unit
When connecting the optional DBR unit, follow Fig. 2-4 (2) and connect the L+2 and L– for 011L,
011H and larger.
The DBR unit and inverter unit will both be damaged if the connection is incorrect.

2-4 Precautions for Wiring to the Control Signal
1) Separate the main circuit wiring (to terminals L1, L2, L3, L+1, L+2, L–, B, U, V, W) from the other
drive wires and power wires.
2) Use a 0.25 to 0.75mm² wire for wiring to the control circuit. The tightening torque must be 0.6Nm.
3) Use a twisted pair wire or twisted pair shield wire for wiring the analog signals (as the setters and meter).
(Fig. 2-6.) Connect the shield wire to the TB2 COM terminal of the VAT2000.
The wire length must be 30m or less.
4) The analog output is dedicated for metering only, such as the speed-meter and ammeter.
It cannot be used for control signals such as the feedback control.
5) The length of the sequence input/output contact wire must be 50m or less.
6) The sequence input (digital I/Os), can be selected either sink logic or source logic method by the
short pin (W1). Refer to Table 5-2.
7) Observe the precautions listed in "Table 5-2 Control input/output circuit".
8) An example of the control circuit wiring is given in Fig. 2-6.
9) The layout of the control circuit terminal block is shown in Fig. 2-7; functions are in Table 5-1.
Terminals with the same terminal symbol are internally connected.
10) After wiring, always check the wiring. Do not test control wirings using a megger or buzzer

3. Test Operation and Adjustment
3-1
Chapter 3 Test Operation and Adjustment
DANGER
• Always install the front cover before turning the input power ON. Never remove the cover while the
power is ON. There are sections in the front PCB that are charged with high voltages.
Failure to observe this could lead to electrical shocks.
• Never touch the switches with wet hands.
Failure to observe this could lead to electrical shocks.
• Never touch the inverter’s terminals while the inverter power is ON even if the operation is stopped.
Failure to observe this could lead to electrical shocks.
• Selection of the retry function could lead to unexpected restarting when a fault occurs. The machine
may start suddenly if the power is turned ON when the automatic start function is selected. Do not go
near the machine.
(Design the machine so that physical safety can be ensured even if the machine restarts.)
Failure to do so could lead to injuries.
• The machine may not stop when a stop command is issued if the deceleration stop function is selected
and the overvoltage / overcurrent limit function is activated. Prepare a separate emergency stop
switch.
Failure to do so could lead to injuries.
• Resetting of a fault while the run signal is input could lead to unexpected restarting. Always confirm that
the run signal is OFF before resetting the alarm.
Failure to do so could lead to injuries.
CAUTION
• The heat sink and resistor are heated to high temperatures, so never touch them.
Failure to observe this could lead to burns.
• Do not block the inverter’s ventilation holes.
Failure to observe this could lead to fires.
• The inverter operation can easily be set from low speeds to high speeds, so confirm that the
operation is within the tolerable range for the motor or machine before making settings.
Failure to do so could lead to injuries.
• Prepare holding brakes when necessary. Holding is not possible with the inverter’s brake functions.
Failure to do so could lead to injuries.
• Confirm the operation of the motor as a single unit before operating the machine.
Failure to do so could lead to injuries or machine damage due to unforeseen movements.
Always prepare a safety backup device so that the machine is not placed in a hazardous situation
when an error occurs in the inverter.
Failure to do so could lead to injuries or machine damage or fires.

3. Test Operation and Adjustment
3-2
The VAT2000 has several modes of control. Some of these include settings that must be made according
to the power supply and motor constants before actually starting operation.
The method to set VAT2000 basic operation is explained in this section.
3-1 Control selection
The VAT2000 has five modes of control, which can be selected with the parameter (C30-0).
Refer to Appendix 1 Control Specifications Table for details.
(1) V/f control (constant torque) (C30-0 = 1) : (Note 1)
V/f control (voltage – frequency control in constant ratio)
(2) V/f control (variable torque) (C30-0 = 2) : (Note 1)
V/f control (voltage-frequency control in quadratic ratio respect to a variable torque load, such as a
fan or pump)
(3) Speed sensor-less vector control for standard Induction Motors (C30-0 = 3)
Speed or torque vector control of the IM is achieved without sensor
(4) Speed sensor vector control for standard Induction Motors (C30-0 = 4) : (Note 2)
Speed or torque vector control of the IM is achieved without sensor.
This is used when a high speed accuracy or fast torque response is required.
(5) Permanent Magnet drive control (C30-5 = 5) : (Note 3)
Speed vector control for permanent magnet motors (brush-less type motors).
The PM motors allow high-efficiency operation in respect to the standard Induction Motors
(Note 1) The operation panel only displays the parameters required for each type control. For example,
when the V/f control is enabled (C30-0 = 1 or 2) the drive will not display the dedicated
parameters for vector control
(Note 2) An optional PCB (U2KV23DN1 or DN2) for IM speed detection is necessary. (Table 7-1.)
(Note 3) An optional PCB (U2KV23DN3) for PM speed detection is necessary. (Refer to Table 7-1.)
3-2 Selection of operation mode
The VAT2000 operates in both “Local” (from the operation panel) and “Remote” (from I/O terminals)
modes. These modes can be changed with the + keys while the motor is stopped. The
selected mode is confirmed by the LCL LED on the operation panel. Refer to Section 4-1 for details.
For Local Mode : LCL LED ON
Operation is carried out from the operation panel.
For Remote Mode : LCL LED OFF
Operation is carried out with the terminal block TB1 input terminals.
CAUTION
Make sure that there is no abnormal noise, smoke or odours at this time.
If any abnormality is found, turn the power OFF immediately.
