lndicates, a potentially hazardous situation which,if not avoided, could

result in death or serious injury to personnel.

Indicates a potentially hazardous situation which, if not avoided,may result

in minor or moderate injury to personnel and d;amage to equipment.

It may also be used to alert against unsafe practices.

Even items described in _ may result in a vital accident in some

situations. In either case,follow these important notes.

O : These are steps to be taken to insure proper operation.

RECEIVING

/_ CAUTION

(Ref. page)

•" Do not install or operate any inverter which is damaged or

has missing parts.

Failure to observe this caution may result in personal injury or

equipment damage.- ....................................... 12

MOUNTING

/_ CAUTION

(Ref. page)

• Life the cabinet by the cooling fin. When moving the

unit, never lift by the plastic case or the terminal covers.|

Otherwise, the main unit may be dropped causing damage

to the unit.. ............................................. 14

• Mount the inverter on nonflammable material (i.e. metal).

Failure to observe this caution can result in a fire.. .............. 14

• When mounting units in an enclosure, install a fan or

other cooling device to keep the intake air temperature

below 122"F (50°C).

Overheating may cause a fire or damage to the unit.. ............ 15

• The VS mini generates heat. For effective cooling,

mount it vertically.

Refer to the figure in "Mounting Dimensions" on page15.

WIRING

Z_x WARNING

(Ref. page)

• Only commence wiring after verifying that the power

supply is turned OFF.

Failure to observe this warning can result in an electrical shock

or a fire.- ................................................ 16

• Wiring should be performed only by qualified personnel.

Failure to observe this warning can result in an electrical shock

or a fire.- ................................................ 16

• When wiring the emergency stop circuit, check the wiring

thoroughly before operation.

Failure to observe this warning can result in personal injury. • ..... 16

(Ref. page)

•Make sure to ground the ground terminal Q.

(Ground resistance : 100_ or less)

Failure to observe this warning can result in an electrical shock

or a fire., ................................................ 17

A'k CAUTION

(Ref.page)

• Verify that the inverter rated voltage coincides with the

AC power supply voltage..

Failure toobservethiscautioncan resultin personalinjury

or a fire.

• Do not perform a withstand voltage test of the inverter.

It may cause semi-conductor elements to be damaged.

• To connect a braking resistor, braking resistor unit or

braking unit, follow the procedures described in

this manual.

Improperconnectionmay causeafire.- ........................ 17

• Make sure to tighten terminal screws of the main circuit

and the control circuit.

Failure to observe this caution can result in a malfunction,

damage or a fire.- ......................................... 16

• Never connect the AC main circuit power supply to

output terminals U, V and W.

The inverter will be damaged and invalidate the

guarantee.. ................................. .............. 16

• Do not connect or disconnect wires or connectors

while power is applied to the circuit.

Failure to observe this caution c_/nresult in personal injury.

• Do not change signals during operation.

The machine or the inverter may be damaged.

OPERATION

/_ WARNING

(Ref. page)

• Only turn ON the input power supply after replacing

the digital operator/blank cover (optional) and switching

the dip switch.Do not remove the digital operator or

the covers while current is flowing.

Failure to observe this warning can result in an electrical shock.. - ••20

• Never operate the digital operator or the switches

when your hand is wet.

Failure to observe this warning can result in an electrical shock.

• Never touch the terminals while current is flowing,even

during stopping.

Failure to observe this warning can result in an electrical shock.

•When the fault retry function is selected, stand clear of

the inverter or the load, since it may restart suddenly

after being stopped.

(Construct machine system, so as to assure safety for personnel,

even if the inverter should restart.) Failure to observe this

warning can result in personal injury.. ........................ 38

• When continuous operation after power recovery is

selected, stand clear of the inverter or the load, since

it may restart suddenly after being stopped.

(Construct machine system, so as to assure safety for personnel,

even if the inverter should restart.) Failure to observe this

warning can result in personal injury.- ........................ 34

• Since the digital operator stop button can be disabled

by a function setting, install a separate emergency

stop switch.

Failure to observe this warning can result in personal injury.

• If an alarm is reset with the operation signal ON, the inverter

restarts automatically.Only reset the alarm after verifying

that the operation signal is OFF.

Failure to observe this warning can result in personal injury.. ...... 20

Z_ CAUTION "

(Ref. page)

• Never touch the heatsink or'braking resistor since

the temperature is very high.

Failure to observe this caution can result in harmful burns

to the body.

• Since it is easy to change operation speed from low to

high speed, verify the safe working range Of the motor

and machine before operation.

Failure toobserve this caution can result in personal injury

and machine damage.

• Install a holding brake separately if necessary.

Failure to observe this caution can result in personal injury.

• Do not change signals during operation.

The machine or the inverter may be damaged.

• All the constants of the inverter have been preset

at the factory. Do not change the settings unnecessarily.

The inverter may bedamaged..• -."........................... 20

MAINTENANCE AND INSPECTION

/_ WARNING

(Ref. page_

Never touch high-voltage terminals in the inverter.

Failure to observe this warning can result in an electrical shock ...... 59

Disconnect all power before performing maintenance

or inspection. Then wait at least one minute after

the power supply is disconnected and all LED's are

extinguished.

The capacitors are still chargecl and can be dangerous." ............ 59

WARNING

(Ref. page)

Do not perform withstand voltage test on any part

of the VS mini.

This electronic equipment uses semiconductors and is

vulnerable to high voltage.. ................................. 59

Only authorized personnel should be permitted to perform

maintenance, inspections or parts replacement.

[Removeall metalobjects (watches,bracelets,etc.)

before operation.[

(Usetoolswhich areinsulatedagainstelectrical shock.)

Failure to observe this warning can result in an electrical shock,. .... 59

/_ CAUTION

(Ref. page)

• The control PC board employs CMOS ICs.

Do not touch the CMOS elements.

They are easily damaged by static electricity.. .................. 59

• Do not connect or disconnect wires or connectors

while power is applied to the circuit.

Failure to observethiscaution canresult in personalinjury.. ....... 59

Others

wAaNING I
