PREFACE

YASKAWA's VS mini is such a small and simple

inverter; as easy as using a contactor. This instruction
manual describes installation, maintenance and

inspection, troubleshooting, and specifications of the
VS mini. Read this instruction manual thoroughly

before operation.

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 to observe 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.

(2) Connect the motor wiring to terminals U, V and W on the main circuit

output side (bottom of the inverter).

(3) Separate the inverter wiring from the motor wiring - 328ft (100m) max.

If the wiring distance between inverter and motor is long, reduce the
inverter carrier frequency. For details, refer to "Reducing motor noise

or leakage current (n37)" on page 42.

(4) Control wiring must be less than 164fl(5om) in length and separate from

the power wiring. Use twisted-pair shielded wire when inputting the
frequency signal externally.

After completing wiring, check the following :
[] Wiring is proper.
[] Wire clippings or screws are not left in the unit.

[] Screws are securely tightened.
[] Bare wire in the terminal does not contact other terminals.

If the FWD (REV) run command is given during the operation mode
(MODE = 1, 3 or 5) from the control circuit terminal, the motor will starl

automatically after the main circuit input power supply is turned ON.

5. OPERATING THE INVERTER

• Test Run

The inverter operates by setting the frequency (speed).
There are two types of operation modes for the VS mini :

(_) Run command from the digital operator.
(_) Run command from the control circuit terminal.

Prior to shipping, the drive is set up to receive run command and frequency
reference from the operator. Below are instructions for running the VS mini

using the digital operator. For instructions on using the control circuit
terminals, refer to MODE description on page 26,
