Safety Precautions

Motor Selection

WARNING

•Use only a Yaskawa permanent magnet motor in combination with this Inverter, specifically SSE4 -F 21. Running any other permanent magnet motor with this Inverter may cause the Inverter to operate abnormally. Consult with Yaskawa before attempting to use a motor other than the model specified.

Confirmations upon Delivery

CAUTION

•Never install an Inverter that is damaged or missing components.

Doing so can result in injury.

Installation

CAUTION

•Always hold the case when carrying the Inverter.

If the Inverter is held by the front cover, the main body of the Inverter may fall, possibly resulting in injury.

•Attach the Inverter to a metal or other noncombustible material.

Fire can result if the Inverter is attached to a combustible material.

•Install a cooling fan or other cooling device when installing more than one Inverter in the same enclosure so that the temperature of the air entering the Inverters is below 45×C.

Overheating can result in fires or other accidents.

Wiring

WARNING

•Always turn OFF the input power supply before wiring terminals.

Otherwise, an electric shock or fire can occur.

•Wiring must be performed by an authorized person qualified in electrical work.

Otherwise, an electric shock or fire can occur.

•Be sure to ground the ground terminal. (200 V Class: Ground to 100 Ω or less, 400 V Class: Ground to 10 Ω or less)

Otherwise, an electric shock or fire can occur.

•Always check the operation of any fast stop circuits after they are wired.

Otherwise, there is the possibility of injury. (Wiring is the responsibility of the user.)

•Never touch the output terminals directly with your hands or allow the output lines to come into contact with the Inverter case. Never short the output circuits.

Otherwise, an electric shock or ground short can occur.

•Do not use the Inverter for any load other than a three-phase AC motor.

•A permanent magnet motor is a type of permanent magnet motor with a rotor in which a magnet is integrated. Unlike an induction motor, the permanent magnet motor terminal generates high voltage when the motor is running, even when the Inverter power is shut off. Be sure to completely stop the motor before wiring, maintenance and inspection.

Failure to do so may result in electric shock.

III

WARNING

•Wire the Inverter so that the Run command switches off when a Stop command (or Fast stop command) is input to terminal BB or terminal BB1.

If the Run command is not removed, then the motor will begin running as soon as the Stop command (or Fast stop command) is cleared.

This can result in personal injury.

CAUTION

•Check to be sure that the voltage of the main AC power supply satisfies the rated voltage of the Inverter.

Injury or fire can occur if the voltage is not correct.

•Do not perform voltage withstand tests on the Inverter.

Otherwise, semiconductor elements and other devices can be damaged.

•Connect braking resistors, Braking Resistor Units, and Braking Units as shown in the I/O wiring examples.

Otherwise, a fire can occur and the Inverter, braking resistors, Braking Resistor Units, and Braking Units can be damaged.

•Tighten all terminal screws to the specified tightening torque.

Otherwise, a fire may occur.

•Do not connect AC power to output terminals U, V, and W.

The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.

•Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits.

The Inverter can be damaged or interior parts burnt if these devices are connected.

•When a magnetic contactor is connected to the output circuits, do not switch it ON and OFF while the Inverter is running.

Surge current will cause the overcurrent protection circuit inside the Inverter to operate.

•This Inverter can drive an induction motor or a permanent magnet motor. Select a suitable control method (parameter A1-02) for the motor you drive.

Failure to do so will cause damage to the motor.

Setting User Parameters

WARNING

•Do not change the factory setting (0) in b1-03 (Run Command source selection).

Doing so can cause the elevator to drop.

•Do not change the factory setting (1) in L8-05 (Input open-phase protection selection).

You can change it to 0, but only after confirming that there are no factors that cause input open phase.

Doing so may damage the Inverter main circuits.

IV

CAUTION

•Disconnect the load (machine, device) from the motor before performing rotational autotuning or pole tuning.

The motor may turn, possibly resulting in injury or damage to equipment. Also, motor parameters cannot be correctly set with the motor attached to a load.

•Stay clear of the motor until rotational autotuning or pole tuning has been successfully completed.

The motor could stop and then start again unexpectedly and this could result in injury.

•Always confirm the following before rotational autotuning or pole tuning:

•The lock key has been removed from the motor shaft.

•There are neither people nor objects around the motor shaft.

•The motor is at a complete stop.

Failure to do so may result in injury.

•Be careful when handling the shaft and coupling.

Failure to do so may result in injury.

•Be careful not to injure yourself with the key groove when turning the motor shaft by hand.

Failure to do so may result in injury.

•When operating a permanent magnet motor for the first time, or after exchanging a permanent magnet motor or an Inverter, set a correct motor parameter to the Inverter before the operation, and be sure to check the motor speed detection.

Shortage of torque may be the cause when the motor is pulled in the load direction or when the motor does not run as directed, such as reverses, doesn't work, or over-accelerates.

Refer to Chapter 4 Trial Operation for details.

•Do not change the parameter settings unnecessarily.

Doing so may impede motor operation.

•When running a permanent magnet motor, be sure to set the following parameters.

•Motor related parameters (E1- , E5- )

•Parameters for PG open-circuit detection function (F1- )

•Parameters for excessive speed deviation detection function (F1- )

•Parameters for over-acceleration detection function (S3- )

Failure to do so will cause damage to the equipment.

•If running a permanent magnet motor with any option cards other than the PG-F2 card, and not using the braking sequence recommended by this Inverter, set the following braking sequences externally.

• After inputting the operational order, or closing the pole detection complete signal, release the braking.

A basket will be pulled by a counter weight. Be careful of this, as it can cause injury.

•If running a permanent magnet motor with any option cards other than the PG-F2 card, note that the Inverter has not been adapted for use with batteries. If so, do not select the battery as the power source for an operation.

Shortage of torque may be the cause when the motor is pulled in the load direction or when the motor does not run as directed, such as reverses, doesn't work, or over-accelerates.

Trial Operation

WARNING

•Check to be sure that the front cover is attached before turning ON the power supply.

An electric shock may occur.

•Provide a separate fast stop switch; the Digital Operator STOP Key is valid only when its function is set.

Injury may occur.

•Reset alarms only after confirming that the RUN signal is OFF.

Injury may occur.

V

CAUTION

•Do not touch the radiation fins (heatsink), braking resistor, or Braking Resistor Unit. These can become very hot.

Otherwise, a burn injury may occur.

•Be sure that the motor and machine is within the applicable ranges before starting operation.

Otherwise, an injury may occur.

•Provide a separate holding brake if necessary.

Always construct the external sequence to confirm that the holding brake is activated in the event of an emergency, a power failure, or an abnormality in the Inverter.

Failure to observe this caution can result in injury.

•If using an Inverter with a elevator, take safety measures on the elevator to prevent the elevator from dropping.

Failure to observe this caution can result in injury.

•Do not check signals while the Inverter is running.

Otherwise, the equipment may be damaged.

•Be careful when changing Inverter settings. The Inverter is factory set to suitable settings.

Otherwise, the equipment may be damaged.

Maintenance and Inspection

WARNING

•Do not touch the Inverter terminals. Some of the terminals carry high voltages and are extremely dangerous.

Doing so can result in electric shock.

•Always have the protective cover in place when power is being supplied to the Inverter. When attaching the cover, always turn OFF power to the Inverter through the MCCB.

Doing so can result in electric shock.

•After turning OFF the main circuit power supply, wait for the time indicated on the front cover, and make sure the CHARGE indicator light has gone out, and then perform maintenance and inspection.

The capacitor will remain charged and is dangerous.

•Maintenance, inspection, and replacement of parts must be performed only by authorized personnel.

Remove all metal objects, such as watches and rings, before starting work. Always use grounded tools.

Failure to heed these warning can result in electric shock.

•Be sure to completely stop the permanent magnet motor before maintenance and inspection.

Failure to do so may result in electric shock.

CAUTION

•A CMOS IC is used in the control board. Handle the control board and CMOS IC carefully.

The CMOS IC can be destroyed by static electricity if touched directly.

•Do not change the wiring, or remove connectors or the Digital Operator, during operation.

Doing so can result in personal injury.

VI

Checking and Controlling the Installation Site

Install the Inverter in the installation site described below and maintain optimum conditions.

Installation Site

1		Install the Inverter under the following conditions in a pollution degree 2 environment.
			Table 1.4 Installation Site
		Type	Ambient Operating Temperature	Humidity
		Enclosed wall-mounted	-10 to + 40 °C	95% RH or less (no condensation)
		(NEMA1)
		Open chassis and IEC IP20	-10 to + 45 °C	95% RH or less (no condensation)

Protection covers are attached to the top and bottom of the Inverter. Be sure to remove the protection covers before installing a 200 or 400 V Class Inverter with an output of 18.5 kW or less in a panel.

Observe the following precautions when mounting the Inverter.

•Install the Inverter in a clean location which is free from oil mist and dust. It can be installed in a totally enclosed panel that is completely shielded from floating dust.

•When installing or operating the Inverter, always take special care so that metal powder, oil, water, or other foreign matter does not get into the Inverter.

•Do not install the Inverter on combustible material, such as wood.

•Install the Inverter in a location free from radioactive materials and combustible materials.

•Install the Inverter in a location free from harmful gasses and liquids.

•Install the Inverter in a location without excessive oscillation.

•Install the Inverter in a location free from chlorides.

•Install the Inverter in a location not in direct sunlight.

Controlling the Ambient Temperature

To enhance the reliability of operation, the Inverter should be installed in an environment free from extreme temperature increases. If the Inverter is installed in an enclosed environment, such as a cabinet, use a cooling fan or air conditioner to maintain the internal air temperature below 45°C.

Protecting the Inverter from Foreign Matter

Place a cover over the Inverter during installation to shield it from metal power produced by drilling.

Always remove the cover from the Inverter after the completion of the installation. Otherwise, ventilation will be reduced, causing the Inverter to overheat.
