    NOTE : POLLUTION DEGREE 2 The inverter must be used in environment of the degree 2. Typical constructions that reduce the possibility of conductive pollution are; 1) The use of an un-ventilated enclosure 2) The use of a filtered ventilated enclosure when the ventilation is fan forced that is, ventilation is accomplished by one or more blowers within the enclosure that provide a positive intake and exhaust.

Type Purchased date Production No. (MFG. No.) Malfunction symptoms If the contents are unclear due to an old nameplate, give only the clear items. To reduce the non- operation time, it is recommended to stock a spare inverter.

    1 Hz can generate a torque of 150%. An Hitachi general purpose motor is given a constant which is a default value. Therefore, in every case, the characteristics will be obtained without trouble. When the characteristics cannot be obtained, measure the motor circuit constant by the autotuning function.

    Operation conditions Quickly varying load Load Revolution The motor revolution varies when the load varies. NOTE: When sensor-less vector is selected, driving of motor at low speed whose constant is different from the factory settings may cause reverse run. In this case, measure the motor constant using the automatic tuning mode or reduce the setting value of primary resistor (R1) of the motor.
