Ease of Maintenance Easy Operation
Field replacement of cooling fan(s) and DC bus capacitors
can be accomplished in a fraction of the time.
Using Logic terminal move to SJ700 without wiring change.
Read SJ300 Parameter by SRW remote operator and write
them in to SJ700
Allows display of only parameters changed from default.
Conformity to global standards
CE, UL, c-UL, C-Tick approvals.
Micro Surge Voltage
suppress function
Wide Input power voltage range
Input voltage 240V for 200V class and 480V
for 400V class as standard.
Logic input & output Terminal
apply sink & source logic
A serial RS-485 Modbus-RTU port is standard.
The SJ700 can communicate with DeviceNet,
PROFIBUS-DP, and other networks with communication
options.

Long life time components &
Life time warning function
Long life time components
Design lifetime 10 Years or more for DC bus capacitors &
Cooling Fan.
Cooling Fan ON/OFF control function for longer fan life.
*Ambient temperature: Average 40 deg C (SJ700B: 30 deg C)
(no corrosive gases, oil mist or dust)
Design lifetime is calculated, and not guaranteed.
Life time warning function
Perform preventive maintenance before a failure occurs
using the Lifetime Warning function.
DC bus capacitor, cooling fan, heat sink temperature and
motor temperature can be monitored in order to replace
components prior to failure.

Data comparison function
-The direct input of function code selection is possible rather
than scrolling through the list.
-Holding down the function key for 3 seconds, causes the
display to jump to output frequency monitor (d001) mode
from any menu location.

EU RoHS compliant
EU RoHS compliant (except solder in power module)
Improvement of environment
Varnish coating of internal PC board & plating of main circuit
copper bus bar are standard.
Versatile Functions
Instantaneous Power Failure
Disregard Function
The SJ700 ignores instantaneous power failure when power
fluctuation happens frequently, as long as DC bus voltage
remains higher than under-voltage trip level.
Emergency stop
Shuts down the inverter by hardware, bypassing
the CPU, to achieve a reliable, emergency stop function.
Intelligent input terminal and output
terminal ON/OFF delay function
Helps simplify external circuits.
Active frequency matching function
Motor frequency match restart function operates
effectively even without motor residual voltage.
Controlled deceleration and stop
on power loss
Analog Input Disconnection
Detection Function
The SJ700 (SJ700B) outputs a disconnection signal when
frequency command through analog input is lost.
Acceleration/Deceleration curve
functions
The curve shape (five kinds, such as S-curve, etc.) can be
chosen according to the application requirements.
Analog Command Holding
Function (AHD)
Output frequency can be changed with UP/DOWN Function,
or with an analog signal as reference value. The set
frequency at power shutdown can be saved, too.
Pulse train input function
Pulse train input for Frequency reference or PID
feed back signal, with SJ-FB (speed feed back card option).
Integrated Input Electric Power
monitor
Input electric power (kW) and Integrated input electric
power for monitoring energy saving.
Automatic Carrier Frequency
Adjustment Function
The SJ700 detects motor current and automatically reduces
carrier frequency according to the current.
The resolution of analog outputs
(voltage, current) is improved to 10 bits.
Hitachi original PWM control method limits motor terminal
voltage to less than two of inverter DC bus voltage.
Lower than Hitachi motor Max. insulation voltage (1,250V)
(During regeneration, the motor terminal voltage may exceed the motor
maximum insulation voltage(1,250V))
