Option board connector
One unit can be mounted (existing communication options for WJ200 can be mounted)
Other optional components
Noise Filter, DC link choke, AC reactor, Braking resistor, Regenerative braking unit, Remote operator
(OPE-SR/OPE-SBK/OPE-SR mini/WOP), Inverter configuration software ProDriveNext, etc.
*1) The output frequency range depends on the control mode and the motor used. Consult the motor manufacturer
for the maximum allowable frequency of the motor when operating beyond 60Hz.
*2) In case that the control mode is changed and the motor constant settings are not appropriate, the desired starting
torque cannot be obtained and also exists the possibility of tripping.
*3) Contact your supplier or local Hitachi sales office when driving SM/PMM.
*4) Input power monitor and output power monitor are reference values. They are not suitable for calculation of
efficiency values, etc. To obtain an accurate value, use an external device.
*5) When a driver error [E30] 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 operating conditions of the inverter, an overcurrent
error may occur instead of a driver error.
*6) At factory setting, the maximum output frequency for analog input signal [Ai1] is adjusted to 9.8 VDC for voltage
input and [Ai2] is adjusted to 19.8 mA for current input. To change the characteristics, refer to the analog
start/end function.
*7) Analog monitor output is a reference output for analog meter connection. The maximum output value may deviate
slightly due to variations in the connected meters and analog output circuits. To change the characteristics, use
[Ao1] adjust function.
*8) The storage temperature is the temperature during transportation.
*9) In case of installing at an altitude of 1000m or more, the atmospheric pressure decreases by approximately 1% for
every 100 m altitude increase. Apply 1% current derating from the rated current by increasing every 100 m, and
conduct an evaluation test. When using at an altitude of 2500 m, please contact your supplier or local Hitachi
sales office.
*10) Insulation distance conforms to UL and CE standards.
