SJ700-022 HFEF2 - Frequency converter - HITACHI
This HITACHI brand SJ700-022 HFEF2 variable frequency drive is a drive from the SJ700 range.
Variable frequency drive: Input: three-phase 400V, 5.8A; Output: 2.2kW, 5.3A.
This HITACHI drive is at your disposal to replace your defective equipment and has a guarantee adapted to your needs.
High performance, powerful functions, user friendly.
A powerful drive with high starting torque and easy configuration
Improved Sensorless Vector Control and Auto Tuning allow for the easy setup of motor constants and enable a high starting torque of 150% or more at 0.5Hz. The SJ700 inverter is a general purpose inverter which can also be applied to high torque applications
Trip avoidance functions
Over current suppression
Higher internal calculation speed improves Current control performance.Over-current suppression helps to avoid an inverter trip during acceleration, deceleration and impact loads.
Over voltage suppression
Using the DC bus AVR Function the deceleration time is controlled in order to avoid exceeding the over-voltage trip level. This enables trip-less operation.
EMC Filter & Brake Circuit integrated as standard
Built-in EMC Filter
Cost and space can be reduced when compared to use of an external EMC Filter.
Brake Circuit up to 30kW
Cost and Space reduction compared with external Braking Controller.
Easy Maintenance
Easy-removable components
Cooling fan(s) and DC bus capacitors can be easily removed for cleaning or replacement.
The removable Logic terminal block of SJ300/L300P are compatible with SJ700. Re-wiring is not necessary
Network compatibility
Various Fieldbus options available
The SJ700 inverters are fitted with a serial RS-485 Modbus-RTU port as standard. The inverters can be connected to the following fieldbus networks, using separately available option boards:
■ PROFIBUS-DB
■ CanOPEN
■ DeviceNet
■ and other networks
Easy Operation
User defined display parameters
The user can select from a number of parameter display modes.
• Data comparison function Displays only those parameters, which have been changed from the default.
• User selected function Displays up to 12 user defined parameters (U001-U012)
• Basic mode (default) Displays commonly used parameters
Long Life time
Life time warning function
Through monitoring of the lifetime warning and other functions, preemptive component maintenance can be carried out to avoid unexpected system failures.
Long life time components
The advanced design of the cooling fan(s) and the DC bus capacitors results in a calculated life time of 10 years*. The ON/OFF control function can extend the life time of the fan(s) even further. *Ambient temperature: SJ700B: 30° C (no corrosive gases, oil mist or dust
Hitachi was founded in 1910 by electrical engineer Namihei Odaira. The same year, the Japanese company designed its very first product: a 5 horsepower induction electric motor. Over the years, the brand has developed technologies adapted to the constant changes in society and consumers.
