■ Sound Basic Functions
● With keypad and the frequency setting potentiometer on the
front panel, you can start
operation easily and immediately.
● Every model has a regenerative braking circuit built-in, so only
an optional braking resistor needs to be connected if required.
● All three-phase and single-phase 200V models with a
capacity of 0.75kW or less are capable of self-cooling without
needing fans.
■ Completely
Noise-Proof
● An optional EMC plate can also be attached with a built-in
noise filter. This facilitates the wiring of shielded cables to
ground, and to the machine ground.
● If leakage current is a problem, disconnecting the grounding
capacitor can reduce it by simply pulling up a jumper switch
(Single-phase 200V and three-phase 400V models).
■
A Wide Variety of Input Terminal Functions
● Two analog input terminals can be used as logic input
terminals by changing parameter settings.
● If the two analog input terminals are switched over to logic
input terminals, up to eight contact input terminals can be
used at a same time.
● A function can be selected from among 65 functions and
assigned to each individual contact input terminal.
● With a slide switch, you can easily switch between sink logic
and source logic configurations.
● Power can be supplied from either the internal power supply
(24V) but also an external power supply (optional). In the
latter case, power is supplied through the PCS terminals.
■ A
Great Variety of Output Terminals
● Three output terminals are provided: a relay contact output
terminal (1c), a relay contact terminal (1a) and an open
collector output terminal.
● The open collector output terminal (DRV-OM) completely
insulated from other terminals, which can also be used as a
pulse train output terminal.
● A function can be selected from 58 functions and assigned to
each individual output terminal.It is also possible to assign
two different functions to a single output terminal,
economizing on the use of terminals and cables.
● Analog output terminals can be be set for 0-10V, 0-1mA or 4-
20mA.
■ Easy
Selection and Installation
● Compact inverters with a wide range of capacities (0.2kW to
15kW) are available.
● Supporting a wide range of supply voltages:
240V class: 200V to 240V
500V class: 380V to 500V
Allowable fluctuations in voltage: +10%, -15%
● Operative in a wide range of ambient temperatures: -10°C to
+60°C (When the ambient temperature is 50°C and over, the
current needs to be reduced.)
■ Dynamic Functions
● A dynamic energy saving mode specially designed for fan
motors provides substantial energy saving compared to
conventional modes.
● The energy saving effect can be checked easily by monitoring
integrated input and output kWh, in addition instantaneous
power.
● A dynamic quick deceleration control mode was added to
conventional deceleration modes achieving faster stopping
without using a braking resistor.
■ A
Wide Choice of Monitor Menu Items
● A list of p to 20 parameters, including load current and torque
current, can be monitored during normal operation.
● Even if the inverter is tripped, monitoring of up to parameters
can continue until power is turned off.When power is turned
off, the last 10 parameters monitored at the occurrence of the
last four trips are retained.
● Up to 16 kinds of monitor menu items and up to 4 kinds of
outputs for adjustments can be assigned to the analog
terminals and the pulse train output terminals. Also,
adjustments can be made easily.
● A free-unit scaling function is provided so that various items,
such as the rotational speed and the line speed, can also be
displayed in addition to the operation frequency. Also, a bias
can be specified.
■ Making
Complicated Settings Easily
● With the automatic torque boost function, the motor can be
tuned easily for vector control. (The rated current, no-load
current and rated rotational speed of the motor need to be set
manually.)
● With the automatic acceleration/deceleration function, the
time can be set easily.
● With the automatic setting function, can be assigned easily to
input terminals on the terminal board.
● With the history function, a parameter that is used repeatedly
can be invoked and changed in one operation.
● Every HF-320Dinverter allows you to specify steps in which a
value changes each time a button on the operation panel is
pressed. For example, if you want to set the freguency by
steps of 10 Hz, this feature comes in very handy.
■ Complete
with Protective Functions
● All possible protective functions are provided to protect the
inverter and its peripheral devices.
● More than 30 kinds of information about causes of tripping and
more than 20 kinds of alarm information can be displayed.
● Every HF-320Dinverter has the function of protecting from
input/output open-phases detecting the breakage of analog
signal cables, and protecting from overcurrent, overvoltage
and overload.
■
Programmable for a Variety of Operations
● A PID control function is provided for every HF-320Dseries,
control devices are not required for PID control. It is also
possible to specify a control waiting time and to put out
command matching signals.
● Up to three different acceleration/deceleration times can be
set, so that the HF-320Dcan be put to a wide range of uses.
● A motor setting can be selected between two. It is possible to
select a base frequency, a voltage, an amount of torque
boost, a thermal protection level, a stall operation level, a V/F
pattern, and so on.
● The output frequency can be set within a range of up to 500Hz.
■
Complete with Communications Functions
● Terminal circuit boards are detachable and replaceable with a
large variety of optional circuit boards.
● An RS485 communications circuit board is optionally
available. It also suports Modbus RTU protocol.
● Optional software program enables you to set parameters
using a personal computer, you can easily check, read, edit,
write and save parameter settings.
● Using the block reading/writing function that was newly added to
communications functions, you can issue a command or
monitor the operating conditions more easily and more quickly.
● Communications circuit boards supporting DeviceNET,
LonWorks, and so on are on the drawing board.
