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.

• 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, Vand 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,
