Increasing voltage of V/f pattern increases motor torque, but an excessive
increase may cause motor overexcitation, motor overheat or vibration.

Note : n25 is to be set to motorrated voltage.

• Full-range automatic torque boost

Motor torque requirement changes according to load conditions. Full-

range autoniatic 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 automatic torque boost gain (n38
factory setting : 1.0). When the wiring distance between the inverter and the

motor is long, or when the motor generates vibration, change the automatic
torque boost gain. In these cases, set the V/f pattern (n24to n30).

• Decreasing Motor Speed Fluctuation

Slip compensation I

As the load becomes larger, the motor speed is reduced and motor slip value
is increased, The slip compensating function controls the motor speed at a

constant value even if the load varies.
When inverter output current is equal to the electronic thermal reference

current (motor rated current), the compensation frequency is added to the
output frequency.

Compensation frequency = Motor rated slip value

4 Electronic thermaloverload protection not provided

The electronic thermal overload function monitors motor temperature,
based on inverter output ciarrent and time, to protect the motor from
overheating. When electronic thermal overload relay is enabled, an

"oL.' l" 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, instal! 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

• 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 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.

O

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

O surge suppressor to the output side.

F

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.
