TOSHIBA

CHAPTER 2 Proper Environment for Installation

2-1

2-2

The VF-SX inverter Is a solid state device. Use caution to install the device in the proper environment, as instructed in the general recommendations shown below. See Chapter 14 for detailed specifications of the proper operating environment.

1. Confirm that the input power supply is within +/- 10% of the nominal voltage. The protective circuit will activate and trip if the permissible input voltage range is exceeded. Extreme voltage conditions may damage the inverter.

2. Do not install the inverter in places where high temperature or humidity are present. Do not install in dusty environments, or environments contaminated with metal particles or metallic powder.

3. Do not mount the inverter on any device subject to intense vibration.

4. Operate the inverter only in an environment between -10 deg C to 40 deg C. The inverter generates heat when operating. When it is installed on a subpanel or backplate be sure there is adequate ventilation on all sides of the inverter, including the back of the inverter where the heat sinks are located. In high ambient temperatures it may be necessary to remove the stick-on seal on the top of the inverter to allow more ventilation through the Inverter.

Certain electrical equipment, if installed too near the inverter, may

cause malfunctions. Examples of this type of equipment can include:

If a magnetic contactor is installed near the inverter install a

urge suppression device across the coil of the contactor to prevent surging magnetic fields from interfering with the operation of the inverter.

Do not install the inverter near fluorescent lighting.

Keep other heat generating electrical equipment, such as resistors

or heaters, away from the inverter.

Always properly ground the inverter chassis to prevent electrical noise

and nuisance tripping. Proper earth ground should not exceed 100 ohms.

Install the inverter ONLY on incombustible subpanels, such as a metal

7. subpanel. If the inverter is installed on a heat insulating subpanel then mount the inverter on a metal subpanel first, and attach this assembly to the insulated subpanel.

Always have at least 10 centimeters free space above and below the

inverter. Always have at least 5 centimeters free space on EACH side of the inverter. If more than one inverter is mounted in a row, leave at least 10 centimeters between each drive, from side to side. If fans are installed in the enclosure or near the drives this space requirement may be reduced. Consult the Toshiba factory for details.

CHAPTER 4 Application Precautions

4-1

4-2

1. If the drive is very lightly loaded (approximately 5*) or if the inertia of the driven load is very small, the drive may become unstable. The result could be abnormal vibration or overcurrent trip. If this condition

persists lower the PWM carrier frequency (parameter [C F]). See Chapter 12 for instructions.

2. Unstable results may occur if:

A. The output rating of the drive is less than the output rating of the

motor.

B. The drive is used with a motor with special ratings, such as an

explosion proof motor, or a motor specially built for high inertia

applications.

C. The drive is used with a pulsing load, such as a load requiring

repeated piston type operation.

3. The motor will coast to stop if the power is lost. If an immediate stop or very quick deceleration of the motor is required use an auxiliary brake device. Select the appropriate stopping method as described in Chapter 11 for an emergency stop.

4. GROUNDING

The inverter should be grounded in accordance with Article 250 of the National Electrical Code or Section 10 of the Canadian Electrical Code, Part I. The grounding conductor should be sized in accordance with NEC

Table 250-95 or CEC, Part I, Table 16.

TOSHIBA

CHAPTER 5 Wiring Guidelines and Precautions

5-1

5-2

This chapter of the manual discusses some of the basic wiring configurations and external devices commonly associated with the installation and application of variable speed drives. Local codes, specifications, requirements, and operating conditions may require the addition of other devices or modifications to the following basic recommendations.

TOSHIBA

5.1 Inverter Wiring

(Refer to Figure 5.1 and 5.2)

1. It can be difficult to remove the upper cover after wiring, so change the jumper selectors J1 or J2 on the internal PC board for "external signal selection" before wiring the inverter. See Chapter 6 for the approximate location of jumpers J1 and J2 inside the drive.

When a signal between 0 to 5V is used as frequency signal, switching the jumper is necessary. Refer to Chapter 10, Table 10-9 for details.

2. Always turn the main line power OFF and confirm that there is no voltage present with a testing tool before connecting power, motor leads, or

control wires.

3. WTOJIN^ Wait until the "CHARGE" lamp has turned off before working on the drive. An internal capacitor stores electrical charge in the inverter and electrocution may result due to inadvertent contact with this

capacitor. Do not touch the terminals or remove the cover while the

"CHARGE" lamp is on. This indicator is located in the lower right-hand

side of the drive near the terminal blocks, and it is a brightly lit red LED when the drive is fully charged.

4. WARNING: Do not wire input power to the output terminals (U, V, W) of the

drive, this will damage the drive. Before energizing, confirm that motor leads are attached to terminals U, V, and W and that the main power leads are attached to terminals R, S, and T.

5. Exercise caution when wiring the control signals, as shown.

A. Install a surge suppressor on any electromagnetic coil on any

contactor wired to the drive. This includes line and load side contactors.

B. Use shielded wire or twisted pair wire for control circuit wiring.

Keep this wire isolated from power wire.

C. Always isolate the input control signals from the main power wiring.

This restriction applies to all control terminals except FLA, FLB, and FLC.

6. Wire sizes:

A. For wire to an ammeter, wire to a frequency meter, and wire carrying

input speed reference signals, use at least 16 gauge shielded wire.

B. For all other control wiring, use at least 12 gauge PVC coated wire.

Figure 5.2 Simplified Power and Control Wiring

Run/Stop

5.2 Installation of a Molded Case Circuit Breaker (MCCB)

1. Install a molded case circuit breaker (HCCB) on the line side of the drive for protection of the incoming power wiring only.

2. Turn the drive ON and OFF via control devices or the touchpad whenever

possible, and not by manual operation of the HCCB or MC. Use the control terminals F. R, and CC to receive control signals from the appropriate remote control devices.

TOSHIBA

5-5

5.3 Installation of a Primary Magnetic Contactor (MC)

1. Install a magnetic contactor (HC) on the line side of the inverter to prevent restart after either a loss of power, a trip of an external overload relay, or an operation of the internal drive protective device.

2. The VF-SX has an internal fault detection relay. The HC can be opened when the inverter protective circuit operates by connecting this contact point to the primary MC operation circuit.

3. The inverter can be used without an HC. In this case use a shunt trip style main breaker (MCCB) and open the main circuit by tripping the breaker when the inverter protective circuitry operates.

4. When using a braking resistor with an overload relay, install an HC or an MCCB with shunt trip on the line side of the inverter. Connect these devices so that the power circuit will open when the internal fault detection relay (Ft) or externally installed overload relay operates. Emergency stop is also possible by connecting the overload relay contact point between the terminals of SS3 (EX) and CC of the inverter. See Chapter 11 for details of the Emergency Stop parameter.

5. Use control signals on terminals F, R, and CC for frequent starting and stopping. Avoid turning the inverter on and off with the primary HC.

6. Always install a surge suppressor across any contactor coil.

5.4 Installation of an Output Magnetic Contactor (MC)

1. Avoid starting and stopping the motor with an output contactor (HC) installed between the inverter and the motor. Excessive surge currents could damage the output devices of the drive. Use control signals on terminals F, R, and CC instead.

2. For Bypass Operation; Be sure the motor has stopped and the drive is OFF before turning on the bypass contactor to run the motor directly from line power. Use an external timer, PLC, or similar device as required. Always make sure that the bypass contactor does not allow voltage to backfeed into the inverter output terminals.

5-6

TOSHIBA

5.5 Installation of an External Overload Relay

1. An electronic overload relay is standard on the VF-SX drive. However, for the following applications Toshiba recomtnends Installing an overload relay that coordinates with the internal solid state relay and the motor connected to the drive. Connect the external relay between the drive and the motor.

A. When using a motor with non-standard current ratings, or the motor

ratings are not comparable to standard duty motors. B. When operating a single motor smaller than the rating of the drive. C. When operating several motors simultaneously from the drive. In this

case Install an overload relay on EACH motor.

2. When applying the VF-SX drive to a constant torque load, change the electronic overload characteristics, or Install a separate overload relay. See

Chapter 11, Parameter [ bHrj.

3. When a motor continuously runs at low speeds it is recommended to use a motor

with an Internal overload relay, for additional protection.

5.6 Installation of an input Reactor

An input reactor Is used to suppress high frequency elements and sudden changes

In power fluctuations. Install an Input reactor when the Inverter Is connected

to electrical systems with the any of the following characteristics:

1. When the power capacity Is 200 KVA or more and the power capacity is

10 times or more than the Inverter capacity.

2. When the Inverter Is connected to the same system as a thyristor commutation type controller.

3. When the inverter Is wired to an electrical system which also contains a distortion source such as an arc furnace or a large capacity inverter.

5.7 Incorrect Wiring and Incorrect External Components

WARHINS: DO NOT INSTALL A POWER FACTOR IHPROVEHENT CAPACITOR ON THE INVERTER INPUT OR OUTPUT. Current and voltage surges associated with the use of power factor capacitors can damage the drive components.

If power factor correction is required add an optional input line reactor to

correct power factor.

TOSHIBA

Radio Freouencv Interference

During operation of the drive there may be noise generated by the drive in the frequency range associated with radio transmission signals. This noise may adversely affect sensitive electronic equipment near the drive. If this condition persists install a RF/EMI (Radio Frequency or Electromagnetic Interference) filter on the input to the drive. Shield the motor leads in metallic conduit. These steps will reduce radio frequency interference. Contact Toshiba for details, or see Chapter 15.

WARWIH6: Do not operate or energize the inverter before checking between the motor and the inverter for mis-wiring or short circuits in the motor. Do not operate the drive if the motor is shorted. Do not ground the neutral point of the motor star

winding.
