  • Page 2 Thank you for choosing this Mitsubishi Transistorized inverter. This instruction manual (detailed) provides instructions for advanced use of the FR-S500 series inverters. Incorrect handling might cause an unexpected fault. Before using the inverter, always read this instruction manual and the instruction manual (basic) [IB-0600026] packed with the product carefully to use the equipment to its optimum.
  • Page 3 2. Fire Prevention Mount the inverter to incombustible material. Mounting it to or near combustible material can cause a fire. If the inverter has become faulty, switch off the inverter power. A continuous flow of large current could cause a fire. Do not connect a resistor directly to the DC terminals P( ), N( ).
  • Page 4 (2) Wiring Do not fit capacitive equipment such as power factor correction capacitor, radio noise filter or surge suppressor to the output of the inverter. The connection orientation of the output cables U, V, W to the motor will affect the direction of rotation of the motor.
  • Page 5 (6) Maintenance, inspection and parts replacement Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. (7) Disposing of the inverter Treat as industrial waste. (8) General instructions Many of the diagrams and drawings in this instruction manual show the inverter without a cover, or partially open.

The torque characteristic is generally smaller than at a start made by the commercial power supply. When large starting torque is necessary, choose automatic torque boost control (set the motor capacity in Pr.

    Terminals P<+> and P1 are designed to connect a dedicated option. Do not connect any equipment other than the dedicated option. In addition, do not short the frequency setting power supply terminal 10 and common terminal 5, and terminals PC-SD.

    .4 Inverter-driven 400V class motor In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is driven by the inverter, consider the following measures: # Measures It is recommended to take either of the following measures:...
