7.2 Common specifications
*1) Output frequency range will depend on the motor control method and the motor used. Consult the motor manufacturer for the maximum
allowable frequency of the motor when operating beyond 60Hz.
*2) In case of the control mode is changed and the motor constant is not set appropriately, the desired starting torque cannot be obtained and also
exists the possibility of tripping.
*3) Regarding the speed range regulation of motor, the variable range depends on the client system and the environment in which the motor is used.
Please contact Hitachi inverter distributers for more information.
*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) If the IGBT error [E030] occurs by the protective function, it may have happened by the short-circuit protection, but also can occur if the IGBT is
damaged. Depending on the operation status of the inverter, instead of the IGBT error, the overcurrent error [E001] may also occur.
*6) At factory setting, the maximum output frequency for analog input signal Ai1/Ai2 is adjusted to 9.8V for voltage input and 19.6mA for current input.
In order to adjust the specification use analog start/end function.
