  • Page 5 Proper use of the products The inverters of the FR-A800 series are only intended for the specific applications explicitly described in this manual. All parameters and settings specified in this manual must be observed. The products described have all been designed, manufactured, tested and documented in strict compliance with the relevant safety standards.
  • Page 6 Safety warnings in this manual Do not use the inverter until you have a full knowledge of the equipment, safety information and in- structions. In this manual, the safety instruction levels are classified into "WARNING" and "CAUTION". WARNING: Assumes that incorrect handling may cause hazardous conditions, resulting in death or severe injury.
  • Page 7 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 8 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 9 Additional instructions Also note the following points to prevent an accidental failure, injury, electric shock, etc. Transportation and installation CAUTION: ● Any person who is opening a package using a sharp object, such as a knife and cutter, must wear gloves to prevent injuries caused by the edge of the sharp object. ●...
  • Page 10 Wiring CAUTION: ● Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved from Mitsubishi. 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 11 Operation WARNING: ● When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop. ● Since pressing the key may not stop output depending on the function setting status, provide a circuit and switch separately to make an emergency stop (power off, mechanical brake operation for emergency stop, etc).
  • Page 12 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 13 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 breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter, etc.
  • Page 14 IP55 compatible models: Waterproof and dustproof performances CAUTION: ● The inverter is rated with an IPX5 waterproof rating and an IP5X dustproof rating when the parameter unit (FR-DU08-01), the front cover, the wiring cover, and the cable glands are securely fixed with screws. ●...

    Introduction Terminology Terminology The terms and concepts below are important for frequency inverters and are used frequently in this guide. Direction of rotation of electric motors The direction (or sense) of rotation of electric motors is defined looking at the end of the motor shaft. If the motor has two shaft ends the direction is defined looking at the main drive shaft end, which is defined as the shaft end away from the end where the cooling fan or the brake are installed.

  • Page 57: Parameter

    Parameter Simple mode parameters Parameter For optimum operation you need to configure your frequency inverter for the specific requirements and specifications of the connected drive system and your application. All the necessary settings are stored in numbered parameters in the inverter‘s memory – you only have to set them once because this memory is not cleared when the power is switched off.

  • Page 58: The Simple Mode Parameters In Detail

    The simple mode parameters in detail Parameter The simple mode parameters in detail 6.2.1 Torque Boost (Pr. 0) Parameter 0 enables you to increase the output voltage at low output frequencies, which increases the motor‘s torque. This function is useful in applications when you need high start-up torque at low speeds.

  • Page 59: Base Frequency (Pr. 3)

    Parameter The simple mode parameters in detail 6.2.3 Base frequency (Pr. 3) The setting of parameter 3 is very important because it matches the frequency inverter‘s output to the requirements of the motor. Parameter 3 specifies the output frequency at which the output voltage is set to its maximum value. This is normally set to the rated frequency of the motor, which can be found on the motor‘s rating plate.
  • Page 60 The simple mode parameters in detail Parameter As the graphic below shows, you can select up to seven frequency setpoint values by applying com- binations of signals to terminals RH, RM and RL.
