I
nverter noises have been reduced with the adoption of new technologies.
¥
Because of the built-in capacitive filter and zero-phase reactor (55K or less),
connecting the optional DC reactor to the inverter will comply with the
electric installation work common specification and machine installation
work common specification (2001) written under the general editorship of
the Japanese Ministry of land, infrastructure and transportation.
¥Because of the built-in EMC filter, the inverter itself can
comply with the EMC Directive (2nd environment*
1
) by
setting the connector to "with filter"(*
2,
*
3
).
(1)
Reduction of electromagnetic noises
•
Because of the built-in inrush current limit circuit, the current
at power on is restricted.
(3)
Equipped with inrush current limit circuit
¥
AC reactor and DC reactor options for the control of
harmonics current output has been miniaturized.
(DC reactor is supplied with the 75K or more as standard.)
(2)
Countermeasures for harmonic current output
EF
•Newly developed noise filter (EMC filter)
(1)
Equipped with operation panel with the popular setting dial
•
From start up to maintenance of the inverter is simple.
•
Possible to save and print parameter setting file making
parameter management simple
(Possible to use communications connecting to any of PU connector and RS-485 terminals)
(2) FR Configurator (setup software)
AGH
•Operation is easy with the popular setting dial.
¥Frequency and parameters can be set without frustrations.
¥
Settings can be made quickly or slowly depending on fast
the dial is being turned.
¥
Settings are certain due to the "clicking" sensation and notch on dial.
•RS-485 terminals are available in addition to the PU.
connector. RS-485 communication can be performed using
the operation panel or parameter unit. Since terminals for
input and output are provided separately, multi-drop
connection is easily done.
•Modbus-RTU (Binary) protocol has been added for
communications in addition to computer link.
(1)
RS-485 terminal is standard equipped
(1)
Complies with UL, cUL, EN (LVD) standards
(1) Remote output function
(2)
Possible to switch sink/source with one-touch
•Possible to connect with LONWORKS, CC-Link Ver.1.1 and Ver.2.0,
DeviceNet
TM
and Profibus-DP when used with communication
options
•You can utilize the on/off of the inverter's output signals
instead of the remote output function of the programmable
logic controller.
•
Possible to switch the logic of I/O terminals. Possible to use in
all regions
(3) Wide voltage range
•
Accommodate both 240V power supply (55K or less) and
480V power supply as standard
(2) Enhanced I/O is standard
•12 contact inputs, 3 analog inputs, 5 open collector outputs, 2
relay outputs, analog output and pulse output are all standard.
•Possible to assign variety of functions to contact inputs, open
collector outputs and relay outputs
•
Possible to switch between voltage and current for the analog input.
•Possible to display the ON/OFF status of the I/O terminals on
the operation panel
(2)
Possible to correspond with major networks
•High torque in low speed region is possible with simple
magnetic flux vector control
(120% torque is possible at 3Hz with slip compensation)
(3)
Simple magnetic flux vector control is possible

*1:
Refer to the EMC instruction manual for compliance conditions.
*2: Leakage current will increase when the EMC filter is selected.
*3: Since the leakage current when using the EMC filter for the 200V class 0.75K and
1.5K is small, the filter is always valid (a setting connector is not provided).
