Ease of Maintenance Easy Operation Easy-removable construction User selection of Parameter for maintenance functions Data comparison function Field replacement of cooling fan(s) and DC bus capacitor can be accomplished in a fraction of the time. Allows display of only parameters changed from default. Using Logic terminal move to SJ700 without wiring change.
Voltage less than 2 times of INV DC voltage E. Output frequency can be changed with UP/DOWN Function Lower than Hitachi motor Max. insulation voltage (1,250V) with analog signal as reference value. The frequency at (during regenerating operation increase the DC bus voltage may over power shutdown can be saved, too.

SJ300 series into the SJ700 series. Copying the parameter settings (that you cannot copy the parameter settings from the SJ700 series to the SJ300 series because the SJ700 series has many new functions and additional parameters.) No display mode selection.
A max. 400Hz can be selected on the SJ700 Series. However, a two-pole motor can attain up to approx. 24,000 rpm, which is extremely dangerous.
When an electromagnetic contactor is installed between the inverter and the motor, do not perform on-off switching during contactor running operation. When used with standard applicable output motors (standard three-phase squirrel-cage four-pole motors), the SJ700 Series Wiring does not need a thermal relay for motor protection due to the internal electronic protective circuit. A thermal relay, however,...
