Page 2 SAFETY For the Best Results with J300 Series inverter, read this manual and all of the warning sign attached to the inverter carefully before installing and operating it, and follow the instructions exactly. Keep this manual handy for your quick reference.
Page 3 Hitachi, Ltd. CAUTION: Be sure to connect a motor thermal switch or overload device to the J300 series controller to assure that the inverter will shut down in the event of an overload or an overheated motor.
Page 4 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.

13. SERVICE When inquiring about inverter trouble, please be ready to inform the distributor where you purchased your unit or the nearest service station the following . 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.

Page 123 Fuzzy most suitable acceleration and deceleration [Outline of the function] The fuzzy most suitable acceleration and deceleration function realizes acceleration and decelera- tion characteristics using the inverter capability at its maximum under fuzzy control to eliminate troublesome setting of the acceleration and deceleration time. The acceleration time is a time for acceleration at the current specified by the overload restriction constant.
Page 124 [Principle] The acceleration and deceleration ratio or acceleration and deceleration are set in accordance with the fuzzy rule from the distance to the overload restriction level and the start slopes of current and voltage. Overload restriction level Restriction angle Setting process The current grows.

Page 128 WARNING If the retry mode is selected, do not approach the inverter unnecessarily. It will be restarted suddenly after it trips/stops. (Design the inverter so that the safety can be assured even in such a restart.) Otherwise, bodily injury will result. NOTE: Since the retry mode is selected, the equipment restarts for trips of overcurrent, overvoltage, or undervoltage.
