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.
