CAUTION

1.

Otherwise, a disaster such as burning could occur.

2-3 Connection

Remove the surface cover to connect the terminal blocks. Correctly connect them according to the fol­lowing procedures.

2-3-1 Basic connection

¬ Always connect the power to the main power supply input terminal of the drive. If it is connected to

another terminal, the drive will be damaged (see Figure 2-3-1).

- Always ground the ground terminal to prevent disasters such as fire and electric shock and to mini­mize noise.

® Use a reliable crimp terminal for connection between a terminal and wire.
¯ After terminating the connection (wiring), check the following items:

a. Whether the connection is correct
b. Whether all necessary connections have been made
c. Whether there is a short-circuit or ground fault between terminals and wires

° Connection modification after power-on

The smoothing capacitor in the direct current part of the main circuit cannot be discharged quickly
after the power is turned off. Use a multimeter to check that the voltage of the direct current (DC) is
reduced to the safety range (25V dc or less) after the charge lamp goes off to avoid danger. Check
that the voltage is zero before short-circuiting a circuit because the residual voltage (electric charge)
may cause sparks.

1. Always connect the ground wire,

WARNING

otherwise electric shock and fire could occur.

2. Ensure that a licensed specialist performs the wiring work.

3. Check before starting the wiring that the power is off,

otherwise electric shock could occur.

U, V, W Drive output Connects 3-phase motor.
P1, P(+) For connection of DC

P(+), N(-) For DC intermediate circuit Connected to DC link circuit terminal

G For drive grounding Ground terminal for drive chassis (case).

(1) Main power supply input terminal

1 Connect the main power supply input terminals to the

power supply via a molded case circuit breaker for circuit
protection or earth leakage circuit breaker. An earth­leakage circuit breaker which can also detect DC current
is recommended. Phase -sequence matching is unneces­sary.

2 It is recommended that a magnetic co ntactor is connected

to prevent any failure or accident from becoming serious
by disconnecting the drive from the power supply when
the drive protective function operates.

3 Do not turn on or off the main power supply to start or stop

the drive; instead, use the control circuit terminal
FWD/REV or the RUN/STOP key on the keypad panel. If
it is unavoidable to turn the main power supply on or off to
start or stop the drive, it must not exceed once per hour.

(2) Drive output terminal [U, V, W]

1 Connect these terminals to the 3-phase motor with the correct phase -sequence. If a motor rota-

tion direction does not correspond to the correct rotation direction, exchange any two of the U, V,
and W phases.

2 Do not connect a phase -advance capacitor or surge absorber to the drive output.
3 A very long wiring length between the drive and the motor causes a high frequency current to

flow due to floating capacity between cables, making the drive trip, increasing the leakage
current and deteriorating the accuracy in the current display. To prevent such trouble, the wi r-

ing length to the motor should not exceed 165 feet (50 m).
When the drive is operated in the low noise mode (carrier frequency: 8 to 15 kHz) and the wi r­ing length is long, add an optional output circuit filter.

Use diagonal cutting pliers to cut the surface cover barriers
from P1, P(+) terminals before connection.
If no DC reactor is used, do not remove the jumper.

(4) Drive grounding terminal[ G]

Always ground the drive grounding terminal [ G]
for safety and noise reduction. Grounding of the
metal frames of electric equipment has to be done
in accordance with the national and local safety
specifications in force.

1 Connect a thick and short wire to the grounding terminal

of the drive for connection with a ground electrode pre­pared exclusively for the drive sy stem.

1. Check that the number of phases and the rated voltage of this product
correspond to the number of phases and voltage of the AC power supply,

FWD terminal is short-circuit to CM terminal in the factory. Pressing the RUN key on the keypad
panel can start forward operation. If function F02 is 0, short-circuit FWD and CM and press the
RUN key for forward operation, or short-circuit REV and CM for reverse operation. If function F02 is
1, then short-circuit FWD and CM for forward operation, or REV and CM for reverse operation.
Regardless of whether function F02 is set to 0 or 1, short-circuiting both FWD – CM and REV – CM
brings the drive to a deceleration-stop. Refer to F02 “Operation method” for details.

(3) Analog input terminal (13, 12, 11, C1)

Use these terminals to connect external input analog voltage and analog current and frequency
setting device (POT). For connecting a contact to this circuit, use a twin contact for fine current si g­nal. Do not use a contact for terminal 11.

WARNING

1. The STOP key is valid only when the function has been set. Prepare an­other switch for emergency stop. When the data of F02 is selecte “2” or “4”,
the operation cannot be stopped using the STOP key on the keypad panel,

otherwise accidents could occur.

*Note the following when wiring:

(1) Surge absorber connection

When the exciting coil of the magnetic contactor or relay in
the control circuit or drive peripheral circuit is opened or
closed, a surge voltage (noise) is generated with a sudden
current change. Due to this surge voltage, the drive control
circuit or peripheral equipment may malfunction. If so, directly
connect a surge absorber to both ends of the coil. (See Fig­ure 2-3-4).)

(2) Co ntrol circuit wiring

1 Wires connected to control circuit terminals must be AWG

20 (0.5mm2) shielded wire or twisted vinyl wire. Remove
the sheath as shown in Figure 2-3-5 and then connect it.

2 Keep the wiring of the main circuit, external relay se-

quence circuit and control circuit as far away from each
other as possible. If they must be adjace nt, cross
them at right angles.

3 Use a twisted-pair shielded wire for long wiring

distances.

(3) Shielding sheath connection

Connect one end of the shielding sheath of a shielded
or twisted-pair shielded wire to the ground terminal as
shown in Figure 2-3-6. Do not connect the other end.

2-4-1 Harmonic component

A harmonic component which may influence the phase -advance capacitor and generator is included
in the drive input current. If necessary , connect a power-factor correcting DC reactor (DCR) (option)
for the drive.

2-4-2 Noise

When noise generated from the drive may affect peripheral equipment, and noise generated from pe­ripheral equipment may malfunction the drive, the following basic countermeasures should be taken.

1. When noise affects other devices via power and ground wires

· Separate the ground of the drive and that of the affected device.

· Connect a noise filter to the drive power wire.

· Use an isolation transformer to separate the power supply of the drive and that of the affected
device.

2) When another device is affected by induction or radiation

· Separate the main circuit wiring of the drive from the control wiring and wiring of the affected de­vice.

· Encase the drive main circuit wiring in a metal tube and ground the metal tube near the drive.

· Encase the drive in a metal rack and ground the rack.

· Connect a noise filter to the drive power wire.

3) When noise generated from peripheral equipment affects the drive

· Use twisted or twisted-pair shielded wires for the drive control wiring. Ground the shields.

· Connect a surge absorber in parallel to the coil of the magnetic contactor and solenoid .

· If the power supply includes much distortion of the waveform or surge, connect an impedance
matching AC reactor for coordination of power supply.

2-4-3 Leakage current

Leakage current flows through the drive I-O wiring and motor stray capacitance when the drive
transistor is turned on and off. Table 2-3-3 lists the countermeasures for the problems caused by the
leakage current.

Table 2-3-3 Countermeasures for leakage current

(2) Check for short-circuits and ground faults between terminals and between live parts.
(3) Check for loose terminals, connectors, and screws.
(4) Check whether the motor is separated from mechanical equipment.
(5) Set switches to OFF before turning on the power so that the drive will not start or operate abnor-

mally at power-on.

(6) Check the following after power-on:

a) Check for alarms displayed on the keypad panel.

1. Always install the surface cover before turning on the power.

WARNING

Do not remove the surface cover during conduction,

2. otherwise electric shock could occur.

3. Do not operate a switch with wet hands,
