*1
To operate the motor beyond 50/60Hz, please consult with the motor manufacturer about the maximum allowable rotation speed.
*2
As for the range of the speed change, the variation range is different according to the installation situation and the characteristic and the usage condition of the motor. Please inquire about details.
*3
The frequency command will equal the maximum frequency at 9.8V for input voltage 0 to 10VDC, or at 19.8mA for input current 4 to 20mA.If this characteristic is not satisfactory for your application, contact your Hitachi sales representative.
*4
Storage temperature refers to the temperature in transportation.
*5
The density of air decreases by 1% whenever rising by 100m when the altitude exceeds 1000m. Therefore, it is necessary to decrease the calorific value. The calorific value of the main circuit semiconductor such as IGBT is proportional to the current and the voltage. Therefore, please decrease by 1% and use the current rating every time it rises by 100m.Please inquires about use in the high ground of 2500m or more.
*6
Function "64(EMR)"cannot be assigned to input terminal 3 by an operation from the operator. The function is automatically assigned to the terminal when slide switch SW1 is set to ON.
*7
The analog voltage monitor and the analog current monitor are rough output values for analog meter connection. The maximum output value might shift a little by the difference of the analog output circuit than 10V or 20mA. Please inquire when there is a possibility that the inconvenience is caused.
*8
When Sensor-less vector control is selected (A044=03), you may not obtain an intended starting torque or motor may trip depending on the applied motor.
*9
The inverter detects IGBT error (E30) as a protection function. However IGBT error (E30) is not a protection for an output short circuit, therefore there is a possibility that IGBT will get damaged. Moreover overcurrent error (E01 to E04) may be detected instead of IGBT error depending on the operational condition of an inverter.
*10
The option can access same as SJ700-2 parameters, cannot access newly added parameters in SJ700D-3.
*11
In case of driving light load application, be able to choose a low capacity inverter. CT and VT is the abbreviation of constant torque mode and variable torque mode.
