Wiring Instructions
(1) Always connect the power input terminals R/L1, S/L2, and T/L3 (R/L1,
S/L2 for single-phase) and power supply via a molded-case circuit
braker (MCCB) or a fuse. Never connect them to terminals
U/T1,V/T2,W/T3, –, +1 or +2.
Refer to page 108 for recommended peripheral devices. For singlephase inverters, always use terminals R/L1 and S/L2. Never connect to
terminal T/L3.

(2) Connect the motor wiring to terminals U/T1, V/T2 and W/T3 on the
main circuit output side (bottom of the inverter).
(3) 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 (n46)” on page 57.
(4) Control wiring must be less than 50m (164ft) in length and separate from
the power wiring. Use twisted-pair shielded wire when inputting the
frequency signal externally.
(5) Tighten the screws on the main circuit and control circuit terminals.
(6) Do not connect or disconnect wiring, or perform signal check while the
power supply is turned ON.
(7) For 400V class inverters, make sure to ground the supply neutral to conform to CE requirements.
(8) Only basic insulation to meet the requirements of protection class 1 and
overvoltage category II is provided with control circuit terminals.
Additional insulation may be necessary in the end product to conform to
CE requirements.
(9) A closed-loop connector should be used when wiring to the main circuit
terminal.
(10) Voltage drop should be considered when determining wire size.
Voltage drop can be calculated using the following equation:
Phase-to phase voltage drop (V)
= √3 × wire resistance (Ω/km) × wiring distance (m) × current (A) × 10-3
Select a wire size so that voltage drop will be less than 2% of the normal
rated voltage.

Wiring the Main Circuit
L1L2 L3
[Example of 3-phase,
200V class, 1.5kW
inverters]
• Main circuit input power supply
Always connect the power supply line to
input terminals R/L1, S/L2, and T/L3
[R/L1, S/L2 for single-phase inverters].
Never connect them to terminal
U/T1,V/T2,W/T3, B1, B2, –, +1, or +2.
Otherwise the inverter may be damaged.
NOTE
For single-phase inverters, always
use terminals R/L1 and S/L2. Never
connect to terminal T/L3.
• Grounding (Use ground terminal
.)
Make sure to ground the ground terminal
according to the local grounding code.
Never ground the VS mini in common
with welding machines, motors, or other
electrical equipment.
When several VS mini units are used
side by side, ground each unit as shown
in examples. Do not loop the ground
wires.
GOOD
GOOD
• Braking resistor connection (optional)
To connect the braking resistor, cut the
protector on terminals B1 and B2.
To protect the braking resistor from
overheating, install a thermal overload
relay between the braking resistor and
the inverter. This provides a sequence
which shuts off the power supply, by a
thermal relay trip contact.
Use this same procedure when
connecting a braking resistor unit.
• Inverter output
Connect the motor terminals to U/T1,
V/T2, W/T3.
Wiring the main circuit terminals
Pass the cables through wiring hole and
connect. Be sure to mount the cover in
its original position.
POOR
Connect with a Phillips (plus) screwdriver.
24
Wiring the Control Circuit
Only basic insulation is provided for the control circuit terminals.
Additional insulation may be necessary in the end product.

5. OPERATING THE INVERTER
Test Run
The inverter operates by setting the frequency (speed).
There are three types of operation modes for the VS mini :
1 Run command from the digital operator (potentiometer/digital setting).
2 Run command from the control circuit terminal.
3 Run command from communications (MEMOBUS communications)
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 (with potentiometer). For instructions on
operation, refer to page 35.
Operation reference or frequency reference constants can be selected
separately as shown below.

• Full-range automatic torque boost
Motor torque requirement changes according to load conditions. Fullrange automatic torque boost adjusts voltage of V/f pattern according to
the requirement. The VS mini automatically adjusts the voltage during
constant-speed operation as well as during acceleration.
The required torque is calculated by the inverter.
This ensures tripless operation and energy-saving effects.

Normally, no adjustment is necessary for torque compensation gain (n63

motor is long, or when the motor generates vibration, change the automatic
torque compensation gain. In these cases, set the V/f pattern (n09 to n15).

Preventing Motor from Stalling (Current Limit)
Automatically adjusts the output frequency and output current according to
the load to continue operation without stalling the motor.
• Stall prevention (current limit) level during acceleration (n56)
Sets the stall prevention (current limit) level during acceleration in units of
1% (Inverter rated current = 100%).
Factory setting: 170%
A setting of 200% disables the stall prevention (current limit) during
acceleration. During acceleration, if the output current exceeds the value set
for n56, acceleration stops and frequency is maintained. When the output
current goes down to the value set for n56, acceleration starts.

The electronic thermal overload function monitors motor temperature, based
on inverter output current and time, to protect the motor from overheating.
When electronic thermal overload relay is enabled, an “OL1” error
occurs, shutting OFF the inverter output and preventing excessive
overheating in the motor. When operating with one inverter connected to
one motor, an external thermal relay is not needed. When operating several
motors with one inverter, install a thermal relay on each motor.

• General-purpose motor and inverter motor
Induction motors are classified as general-purpose motors or inverter
motors, based on their cooling capabilities. Therefore, the motor overload
function operates differently between these two motor types.

Using MEMOBUS (MODBUS) Communications
Serial communication is available with VS mini using programmable
controller (MEMOCON series) and MEMOBUS. In order to perform serial
communications, RS-485/422 interface card (optional) must be installed.
Refer to MEMOBUS Instruction Manual (Manual No.: TOEZ-C736-70.1)
for details of communications.
MEMOBUS (MODBUS) communications
MEMOBUS system is composed of a single master (PLC) and slaves (1
to 31 VS-mini units).
Communication between master and slave (serial communication) is
controlled according to the master program with the master initiating
communication and the slave responding.
The master sends a signal to one slave at a time. Each slave has a preregistered address No., and the master specifies the number and conduct
signal communications. The slave receives the communication to carry
out designated functions and reply to the master.

Using Constant Copy Function
Constant copy function
The digital operator for remote operation (Model JVOP-146, Optional) can
store constants for one inverter. A backup power supply is not necessary
since EEPROM is used.
Note: When using a digital operator for remote operation, use with a remote
interface unit for remote operation (optional) and the cable for remote
operation (optional). Refer to the VS mini J7 catalog (Literature No.
KAE-S606-12) for details.
Constant copy function is possible only for the inverters with same product
series and power supply specifications. However, some constants may not
be copied. It is also impossible to copy constants between VS mini and VS606V7 inverters.
The prohibition of the reading of constants from the inverter can be set at
n77. The constant data cannot be changed when this constant is set.
If any alarm occurs during constant copy, the PRGM will blink and copying
will continue.
• Constant copy function selection (n76)
Depending on the setting of n76 for constant copy function selection, the
following functions are available:
(1)
Read all the constants from the inverter (READ) and store them in
EEPROM in the digital operator.
(2)
Copies the constants stored in the digital operator to the inverter (COPY).
(3)
Verify that the constants in the digital operator and the constants in
the inverter are the same (VERIFY).

A 3-wire sequence is in effect.
The multi-function input method
(n37) is set to 3-wire sequence, and
the S2 control terminal is not
closed.
To use a 3-wire sequence, make
the wiring so that the S2 control
terminal is closed. To use a
2-wire sequence, set the multifunction input (n37) to a value
other than 3-wire sequence.
The frequency reference is too

For analog input, make sure that
the frequency reference (n03)
and SW settings are correct.
The stall prevention level during
acceleration is too low.
Because the stall prevention level
during acceleration (n56) is set too
low, the output current reaches the
set level, the output frequency is
stopped, and the acceleration time
is lengthened.
Check if the stall prevention level
during acceleration (n56) is set to
an appropriate value.
The stall prevention level during
running is too low.
Because the stall prevention level
during running (n57) is set too low,
the output current reaches the set
level, and the speed drops.
Check if the stall prevention level
during running (n57) is set to an
appropriate value.
The load is too heavy.
If the load is too heavy, stall
prevention is activated, the output
frequency is stopped, and the
acceleration time is lengthened.
Lengthen the set acceleration

• Ground fault interrupter:
Select a ground fault interrupter not affected by high frequencies. To
prevent malfunctions, the current should be 200mA or more and the
operating time 0.1 sec. or more.
Example : • NV series by Mitsubishi Electric Co., Ltd. (manufactured in
1988 and after)
• EGSG series by Fuji Electric Co., Ltd. (manufactured in 1984
and after)
• AC and DC reactor :
Install an AC reactor to connect to a power supply transformer of large
capacity (600kVA or more) or to improve power factor on the power
supply side.
• Noise filter:
Use a noise filter exclusively for inverter if radio noise generated from the
inverter causes other control devices to malfunction.
NOTE
1. Never connect a general LC/RC noise filter to the inverter output circuit.
2. Do not connect a phase advancing capacitor to the I/O sides and/or a
surge suppressor to the output side.
3. When a magnetic contactor is installed between the inverter and the
motor, do not turn it ON/OFF during operation.
For the details of the peripheral devices, refer to the catalog.
