Hitachi SJ700 Series - Safety Precautions

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 SJ700D/SJ700 without wiring
change.
Read SJ300 Parameter by WOP remote operator and write
them in to SJ700D/SJ700
Displays only parameters changed from factory default
The Modbus-RTU communication is embedded as standard
along with a dedicated terminal.
Other fieldbus communications such DeviceNet and
PROFIBUS-DP are supported with optional fieldbus modules.

Long lifetime components &
Lifetime warning function
Long lifetime components
Design lifetime 10 Years or more for DC bus capacitors & Cooling
Fan.Cooling Fan ON/OFF control function for longer fan life.
*Condition for lifetime calculation -
Ambient temperature: 40 deg C (SJ700B: 30 deg C)
Ambient condition: No corrosive gas, oil mist nor dust
10 years is a design lifetime base on calculation, and not guaranteed
Lifetime warning function
Lifetime warning function helps to perform preventive
maintenance before a failure occurrence.
DC bus capacitor, cooling fan, heat sink temperature and
motor temperature can be monitored in order to replace
components prior to failure.
