Introduction Chapter 1

H Energy-saving Operation
• The rotation speed of a three-phase induction motor does not decrease when the supply voltage
drops
if the motor has a light load. The 3G3HV Inverter in energy-saving operation automatically de
-
tects
the current consumption of the motor connected to the Inverter
, estimates its load, and drops the
output voltage, thus saving the power consumption of the motor efficiently.
• Use
the auto-tuning function of the Inverter in energy-saving mode to reduce the power consumption
of the motor most efficiently if the ratings of the motor are unknown.
• The Inverter in energy-saving mode is ideal for the following applications.
S Rotation control of fans and blowers
S Flow control of pumps
S Control of machines with variable loads, such as metal-working machines, wood-working ma-
chines, and food-processing machines
S Control of machines that mainly operate with light loads
H PID Control
• The Inverter has a PID control function, thus performing follow-up control with ease.
• Follow-up control is a control method in which the Inverter uses a sensor and senses the rotation
speed of the motor and changes the output frequency to control the rotation speed of the motor.
• Follow-up control can be applied to a variety of control operations.
• PID control is ideal for the following applications.
S Speed control: With a speed sensor, such as a tachometric generator, the Inverter regu-
lates
the rotation speed of the motor regardless of the load of the motor or
synchronizes the rotation speed of the motor with that of another motor.
S Pressure control: With a pressure sensor, the Inverter performs constant pressure control.
S Current control: With a current sensor, the Inverter performs precise current control.
S Temperature control: With
a temperature sensor and fan,
the Inverter performs temperature con
-
trol.
H Frequency Reference
• The
following three types of frequency references
are possible to control the output frequency of the
Inverter.
S Numeric input from the Digital Operator of the Inverter
S Voltage input within a range from 0 to 10 V
S Current input within a range from 4 to 20 mA
The Inverter can use one of the above if it is designated with parameters.
• A
maximum of four frequency references can be registered with the Inverter
. With remote multi-step
input, the Inverter can be in multi-step speed operation with a maximum of four speed steps.
H Frequency Jump
• The
frequency jump function prevents the Inverter from generating any frequency that causes the ma
-
chine to resonate.
Introduction Chapter 1
1-4
H Acceleration/Deceleration Time Settings
• The
acceleration time and deceleration time of the Inverter can be set independently within a range of
0.0 to 3,600 s.
• Two
acceleration times and two deceleration times can be
set with the Inverter
, any of which can be
selected with remote output.
H V/f Settings
• Select a V/f pattern out of the 15 V/f patterns preset with the Inverter according to the application.
• An optional V/f pattern can be set with the Inverter.
H Monitor Function
• The following items can be monitored with the Digital Operator.
Frequency
reference, output frequency
, output current, output voltage, DC voltage, output power
,
status of input terminals, inverter status, power interruption error, PROM number, total operating
time, and PID feedback value
H Low Noise (3.7- to 160-kW Models)
• The
output transistor of the Inverter is an IGBT (insulated gate bipolar transistor). Using a sine-wave
PWM method with a high-frequency carrier, the motor does not generate metallic noise.
H High Torque at Low Output Frequency Range
• A
torque rate of 150% can be achieved even in a low
speed range where output frequency is only 3 Hz.
H Automatic Torque Boost
• The
Inverter automatically adjusts the output according to the required torque of the motor that is
rotat
-
ing at constant or accelerative speed, thus ensuring the powerful rotation of the motor.
H Harmonic Countermeasures (3.7- to 160-kW Models)
• DC reactors (optional) can be connected to 3.7- to 15-kW models.
• Models of 18.5- to 160-kW have a built-in DC reactor and also employ 12-pulse rectification, which
suppresses harmonics better than a reactor.

1-3 Additional Functions
New functions have been added to the following versions, for which production was
started in April 1997.
3.7 to 15-kW models: Software version S2011 (VSP102011) or later
18.5 to 55-kW models: Software version S3012 (VSP103012) or later
Note:
The software version can be confirmed by viewing the 4-digit PROM number with
the monitor function. This number is set to the number of the software version.
The
functions that have been added with these versions and outlines of these functions
are given below. For details of the functions, refer to
Section 4 Operation
.
H Independent Initialization for Motor Rotation Direction
Although
the functionality of the forward/reverse rotation selection parameter (n005) itself has not been
changed,
with new models it will not be initialized when the parameter write prohibit selection/parame
-
ter initialization parameter (n001) is set to 6 or 7.
H V/f Default Settings Changed (Inverters of 55 kW or More)
The
default settings for V/f patterns have been changed for
the Inverters of 55 kW or more as shown
below.
Model Intermediate output frequency
voltage (n016)
Minimum output frequency
voltage (n018)
3G3HV-A2550 12.0 V 6.0 V
3G3HV-A4550 24.0 V 12.0 V
H Output Frequency Upper Limit Changed
The upper limit of the setting range for the output frequency upper limit parameter (n030) has been
changed.
The addition of a slip compensation function means that frequencies greater than the maxi
mum frequency (n012) may occur (because the frequency reference is added to the compensation
value).
For this reason, the upper limit of the setting range of the output frequency upper limit parameter
(n030) has been increased from 100% to 109%.
H PID Input Characteristic Selection Function (n039)
A
PID input characteristic selection input (set value: 27) function has been added to the multi-function
input 5 parameter (n039) that determines the function of terminal S6.
H Carrier Frequency Settings Increased (n050)
The setting 7.0 Hz (set value: 10) has been added to the available carrier frequency settings.
H Minimum Baseblock Time Setting Range Increased (n053)
The
setting range for the minimum baseblock time has been increased from the range 0.5 to 5.0 s to the
range 0.5 to10.0 s for increased motor responsiveness.
H Slip Compensation Function (n109 to n111)
A
function that compensates for motor slip, a characteristic of induction motors, has been added. Using
this
function, the amount of slip is estimated
from the output current of the Inverter
, and the output fre
-
Introduction Chapter 1

quency
is compensated accordingly
. By using the slip compensation function, speed fluctuations of the
load can be reduced more effectively than with previous models.
H Changing Parameters while Inverter is Running
It
is now possible to change some
parameters and, related to this, monitor and set the items in the bot
tom
two lines of
easy-setting indicators while the Inverter is running. Using this feature, set values for
some
parameters can be adjusted while monitoring operation. For details of which parameters can be
changed while the Inverter is running, refer to the parameter lists.
H Operation Selection at Digital Operator Interruption Function (n112)
A
function that detects communications errors between the Digital Operator and the Inverter itself, and
interrupts Inverter outputs has been added.
H Settable Detection Width (n113)
The
detection width of the optional frequency agreement and
the optical frequency detection can be set
with parameters. With previous models this setting was fixed.
H Operation Selection at Operation Mode Switching (Local/Remote
Switching) (n114)
Using
the Operation Mode Selection Key on the Digital Operator or operation mode selection input set
using the multi-function input parameters (set value: 5), it is possible to switch between operation from
the
Digital Operator and operation according
to the setting of the operation mode selection parameter
(n002). A function that selects whether run signals input while the operation mode is switching are
enabled or disabled after the mode has changed, has been added.
Note If
this setting is set to enable run commands, when the operation mode changes the Inverter will
start running immediately. Take steps to ensure safety for such operation.
