*1. The output frequency range depend on the control and motor used. When running the inverter exceeding 60 Hz, check
      the maximum allowable frequency with the manufacturer of the motor.
*2. When the control mode is changed, unless the motor constant is appropriately configured, you cannot obtain the desired
      starting torque or the inverter may trip.
*3. The variable range of motor speed may vary depending on your system or the environment where the motor is used.
      Please contact us for details.
*4. Both the input power and output power are reference values, which are not appropriate for use in calculation of efficiency
      values, etc. To obtain an accurate value, use an external device.
*5. The IGBT error [E030] is generated by the protective function not only for short circuit protection but also when IGBT is
      damaged. Depending on the operating conditions of the inverter, the overcurrent error [E001] may occur, instead of the
      IGBT error.
*6. At the factory default setting, when voltage and current on Ai1/Ai2 terminal is changed using a switch, with input of
      voltage at 9.8 V and current at 19.8 mA, the maximum frequency is commanded. To change characteristics, make
      adjustments using the analog start/end function.
*7. The threshold for signal output varies depending on the motor to be combined with the inverter, parameter adjustment,
      etc.
*8. The output data of analog voltage monitor and analog current monitor are reference values for connecting an analog
      meter. Due to the meter to be connected and variation in analog output circuit, the maximum output value may slightly
      vary from 10 V or 20 mA. To change characteristics, make adjustments using the Ao1 adjustment and Ao2 adjustment
      functions. Some monitor data cannot be output.
*9. To enable the EMC filter, connect with a power supply grounded at a neutral point. Otherwise, the leakage current may
      increase.
*10. Use the 400 V class inverter at an input voltage of 500 VAC or below. If input voltage exceeds 500 VAC due to
        fluctuation of power, use the inverter at 40°C or lower ambient temperature.
*11. The storage temperature is the temperature during transport.
*12. To be in accordance with the testing method specified in JIS C 60068-2-6: 2010 (IEC 60068-2-6:2007)
*13. When the inverter is used in a location at 1000 m or higher altitude, air pressure reduces approximately 1% every 100
        m elevation. Perform 1% current der- ating and conduct evaluation for every 100 m elevation.
*14. For insulation distance, comply with UL and CE standards
*15. When a clock function is used, the optional battery (CR2032, 3 V) is required. When you purchase, this LCD operator
       does not come with the battery.

*1. In FreeRun mode, slaves perform I/O processing, i.e., refresh I/O data asynchronously with the communications cycle of
      the master. The communications cycle is determined by the cycle time of the master. For the communications response
      time of the EtherCAT Communication Unit, refer to the EtherCAT Communication Unit User’s Manual (Cat.No. I663) for
      details.
Note that FreeRun mode in the synchronization mode has a different meaning from free-run stop of an Inverter.
