•This manual may be modified when necessary because of improvements to the product, modifications, or changes in specifications.

Such modifications are indicated by revising the manual number.

•To order a copy of this manual, or if your copy has been damaged or lost, contact your OMRON representative.

•OMRON YASKAWA is not responsible for any modification of the product made by the user, since that will void the guarantee.

NOTATION FOR SAFETY PRECAUTIONS

Read this instruction manual thoroughly before installation, operation, maintenance, or inspection of the V7AZ. In this manual, safety precautions are classified as either warnings or cautions and are indicated as shown below.

WARNING

Indicates a potentially hazardous situation which, if not avoided, may result in death or serious injury.

CAUTION

Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or damage to equipment.

It may also be used to alert against unsafe practices.

Even items classified as cautions may result in serious accidents in some situations. Always follow these important precautions.

NOTE : Indicates information to insure proper operation.

PRECAUTIONS FOR UL/cUL MARKING

•Do not connect or disconnect wiring, or perform signal checks while the power supply is turned ON.

•The Inverter internal capacitor is still charged even after the power supply is turned OFF. To prevent electric shock, disconnect all power before servicing the Inverter, and then wait at least one minute after the power supply is disconnected. Confirm that all indicators are OFF before proceeding.

•Do not perform a withstand voltage test on any part of the Inverter. The Inverter is an electronic device that uses semiconductors, and is thus vulnerable to high voltage.

•Do not remove the Digital Operator or the blank cover unless the power supply is turned OFF. Never touch the printed circuit board (PCB) while the power supply is turned ON.

•This Inverter is not suitable for use on a circuit capable of delivering more than 18,000 RMS symmetrical amperes, 250 V maximum (200 V Class Inverters) or 18,000 RMS symmetrical amperes, 480 V maximum (400 V Class Inverters).

CAUTION

• Use 75°C copper wire or the equivalent.

PRECAUTIONS FOR CE MARKINGS

•Only basic insulation to meet the requirements of protection class 1 and overvoltage category II is provided with control circuit terminals. Additional insulation may be necessary in the end product to conform to CE requirements.

•For 400 V Class Inverters, make sure to ground the supply neutral to conform to CE requirements.

•For conformance to EMC directives, refer to the relevant manuals for the requirements.

Wiring Instructions

NOTE 1. Always connect the power supply for the main circuit

inputs to the power input terminals R/L1, S/L2, and T/L3 (R/L1, S/L2 for single-phase power) via a molded-case circuit breaker (MCCB) or a fuse. Never connect the power supply to terminals U/T1, V/T2, W/T3, B1, B2, −, +1, or +2. The Inverter may be damaged.

For single-phase Inverters, always use terminals R/L1 and S/L2. Never connect terminal T/L3. Fuses must be of ULclass RK5 fuse or an equivalent.

Refer to page 231 for recommended peripheral devices.

Inverter Power Supply Connection Terminals

2.If the wiring distance between Inverter and motor is long, reduce the Inverter carrier frequency. For details, refer to

Carrier Frequency Selection (n080)14kHz max on page 94.

3.Control wiring must be less than 50 m (164 ft) in length and must be separated from power wiring. Use shielded twisted-pair cable when inputting the frequency signal externally.

4.Only basic insulation to meet the requirements of protection class 1 and overvoltage category II is provided with control circuit terminals. Additional insulation may be necessary in the end product to conform to CE requirements.

5.Closed-loop connectors should be used when wiring to the main circuit terminals.

6.Voltage drop should be considered when determining the wire size.

Voltage drop can be calculated using the following equation:

Phase-to-phase voltage drop (V)

= 3 × Wire resistance (Ω/km) × Wiring distance (m) × Current

(A) × 10-3

Select a wire size so that voltage drop will be less than 2% of the normal rated voltage.

7.If the Inverter is connected to a power transformer exceeding 600 kVA, excessive peak current may flow into the input power supply circuit, and break the converter section. In this case, attach an AC reactor (optional) to the Inverter input side, or a DC reactor (optional) to the DC reactor connection terminal.
