    ● A person who took a proper engineering training. Such training may be available at your local Mitsubishi Electric office. Contact your local sales office for schedules and locations. ● A person who can access operating manuals for the protective devices (e.g. light curtain) connect- ed to the safety control system.
  • Page 6 Electric Shock Prevention WARNING: ● While power is on or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock. ● Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high-voltage terminals or the charging part of the circuitry and get an electric shock.
  • Page 7 Fire Prevention CAUTION: ● Mount the inverter to incombustible material. Install the inverter on a nonflammable wall without holes (so that nobody can touch the inverter heatsink on the rear side, etc.). Mount- ing it to or near combustible material can cause a fire. ●...
  • Page 8 Electric product, the product will be damaged. Halogen-based materials are often in- cluded in fumigant, which is used to sterilize or disinfect wooden packages. When packaging, prevent residual fumigant components from being infiltrated into Mitsubishi Electric prod- ucts, or use an alternative sterilization or disinfection method (heat disinfection, etc.) for packaging.
  • Page 9 CAUTION: ● Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved from Mitsubishi Electric. These devices on the inverter output side may be overheated or burn out. ● The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence (U, V, W) is maintained.
  • Page 10 CAUTION: ● The electronic thermal relay function does not guarantee protection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection. ● Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.
  • Page 11 Test operation and adjustment CAUTION: ● Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected motions. Emergency stop CAUTION: ● Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails.

When the load operating condition deviates from the normal range, the protective function is activated or the warning is output to protect the inverter or the motor.
  • Page 362 (H) Protective function parameter Parameters Load characteristics setting (Pr. 1481 to Pr. 1487) ● Use Pr. 1481 to Pr. 1485 to set the reference value of load characteristics. ● Use Pr. 1486 "Load characteristics maximum frequency" and Pr. 1487 "Load characteristics mini- mum frequency"...
  • Page 363 Parameters (H) Protective function parameter Read value of Pr. 1480 Status Tens place Ones place — During measurement from Point 4 to Point 5 — Normal completion Termination of measurement by an activation of a protective function, inverter reset, 1 to 5 turning ON of MRS signal, turning OFF of the start command, or timeout.
  • Page 364 (H) Protective function parameter Parameters Load fault detection setting (Pr. 1488 to Pr. 1491) ● When the load is deviated from the detection width set in Pr. 1488 "Upper limit warning detection width", Upper limit warning detection signal (LUP) is output. When the load is deviated from the detection width set in Pr.
  • Page 365 Parameters (H) Protective function parameter Setting example ● The load characteristics are calculated from the parameter setting and the output frequency. ● A setting example is shown below. The reference value is linearly interpolated from the parameter settings. For example, the reference when the output frequency is 30 Hz is 26%, which is linearly interpolated from values of the reference 2 and the reference 3.

    (H) Protective function parameter Parameters 5.7.13 Motor overspeeding detection The Overspeed occurrence (E.OS) is activated when the motor speed exceeds the overspeed detec- tion level. This function prevents the motor from accidentally speeding over the specified value, due to an error in parameter setting, etc. Initial Setting Name...
