  • Page 22: For Correct Operation

    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.
  • Page 23 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,...
