Introduction
Thank you for your purchase of Drivecon Corporation's VF61 series inverter.
Please read through this instruction manual carefully prior to using it and get familiar ith proper
installation, iring and operations to ensure optimum and trouble-free operation.
This instruction manual describes the basic and standard operation procedures. See the catalog for
the specifications, capacity, outer dimensions, environmental conditions and so forth.
The VF61 series is to be used for a custom designed product or system, use the values ritten in the
dra ings or test report of them, not the values sho n in this manual.
Precautions for Safe Operation
1. Supply the specified voltage to the input terminals of the inverter. (If 400V po er supplied to
the 200V type inverter, the inverter ill be broken.)
2. Provide the input side of the inverter ith an MCB of the proper capacity.
3. Be sure to connect the inverter to the ground to prevent accidents.
4. Do not connect the supply line to the output of the inverter. Other ise, the inverter ill be
broken.
5. Do not connect a phase advancing capacitor to the output terminals of the inverter.
Other ise, the inverter ill be broken.
6. Before maintenance ork or inspection, turn the inverter po er off to avoid electric shock.
Wait until the "CHG" LED goes out. Note that the heatsink may be hot in some operating
conditions.
7. Do not change the parts or make reckless alterations.
8. The inverter has no noise suppression device. Please contact us if such a device is necessary.
Memory protection
We recommend that set data be protected against re riting in order to prevent misuse of the console.

1. Before starting operation
1.1 Checking supplied components and parts.
When you receive the VF61, check it carefully.
(1) Make sure that the specifications of VF61, accessories and spare parts are properly in
accordance ith your order. Check the logo mark on the cover to see if the unit type is as
you ordered.
Example: 2R2: 2.2
3R7: 3.7 200V type: 22
5R5: 5.5 400V type: 44
7R5: 7.5 Voltage (V)
Inverter capacity (kW)
Applicable po er source INPUT: 380 to 460V, 3-phase, 50/60 Hz
OUTPUT: 2.2kW, 5.5A
(2) Make sure that the supplied VF61 hasn't been damaged during transportation.
(3) Make sure that no scre s, bolts, etc. are loose or dislocated.
If you find some problems, contact the dealer you purchased the VF61 from.

1.2.2 Opening of front cover
If you are going to inspect the VF61 or carry out automatic measuring (described in section 3
belo ), open the front cover as sho n belo .
(1) Remove the fixing scre s from the bottom of the front cover.
(2) Dra the front cover to the front.
(3) When the front cover is fully opened, push it. The cover is fixed in the Up position.
1.3 Installation
1.3.1 The installation condition has great influences upon the service life and reliability of the
inverter. Do not use the inverter in the places sho n belo . Be sure to run the inverter in the op-
erating conditions sho n in the catalog.
(1) A moist or dusty place. A place exposed to ater or oil drips.
If the inverter is used in such a place, the circuit insulation is deteriorated, resulting in shorter
service life of the parts.
(2) Extreme heat or cold out of the specified temperature range.
If the service temperature is too high, bad influences are caused upon capacitors, and parts of
cooling fan or motor, etc.
(3) A place exposed to corrosive gas
Corrosive gas deteriorates the reliability of the parts and/or connecting part.
(4) A place ith much vibrations.
Vibrations cause poor contact of the connectors, disconnection of ires, damage to parts,
etc.
1.3.2 Installation direction
If the VF61 is used separately or built into a control panel, follo the instructions belo .
(1) Installation direction
Install the VF61 vertically ith its marking "VF61" up ard as sho n belo .

-3-
(2) Securing cooling spaces
Provide the VF61 ith proper cool-
ing spaces as sho n on the right.
The cooling fan takes air from the
bottom and exhausts it to the top.
Secure enough spaces so that a ire
duct, etc. do not hinder proper
ventilation.
Install peripheral devices so that heat
generated by them does not reduce
the cooling efficiency of the VF61.
1.4 Circuit construction and riting terminal
1.4.1 Circuit construction
The follo ing sho s the standard circuit construction of the VF61.
Safety Precautions
1. Supply the specified voltage to the inverter. If 400V po er is applied to the 200V type
inverter, damage ill occur. (Note 1)
2. Be sure to provide the inverter ith an MCB of the proper capacity. See 1.5 belo .
(Note 2)
3. Be sure to connect the inverter and motor to the ground to prevent accidents.
(Note 3)
4. Connect a motor to the inverter output terminals. Do not connect the supply line to them.
Other ise, the inverter ill be damaged.
(Note 4)
Options
1. Connect a dynamic brake resistor. (Note 5)
2. Connect a DC reactor DCL. (Note 6)

Safety Precaution
Terminals 10 and 34 carry 0V of the control circuit. Never connect these terminals to GND.
1.4.2 Terminal blocks
(1) Main circuit terminal block
R, S and T Connect AC po er to these terminals. (Do not supply 400V to the
200V type inverter.)
Terminal 1 and 2 Connect the ires of the optional DC reactor DCL to these terminals.
These terminals are short circuited before shipment.
Terminal 2 and B Connect the optional dynamic braking (DB) resistor to these terminals.
Terminal 2 and 0 Connect the optional DB unit and resistor to these terminals.
(2) Control terminal block
