PLC long-term supply a full range of Hitachi PLC: EH-150, MICRO-EH series and parts, following a drive, PLC repair operations and energy-saving-conversion project! ? SJ700 series of high starting torque and the efficient functioning of debugging simple, convenient debugging complex motor fixed number to achieve the above 0.3Hz200% high starting torque. 1. Use a lift, even if 0Hz command also ensures torque - even if the speed command to 0Hz also ensures 150% torque, ideal for when you start from a low starting torque required momentary lift cranes. 2. overcurrent suppressing function (high-speed current control), overvoltage suppression function greatly accelerate the speed of the drive internal calculus? - Significantly improve the performance of current control, overcurrent suppression function, overvoltage suppression function, load need not be adjusted according to the necessary acceleration deceleration time, reduce the incidence of tripping 3. A button can be achieved not by an emergency stop inverter output frequency of the CPU, hardware circuit disables the output - can achieve safe and reliable operation of the emergency shutdown 4. Micro-surge voltage suppression (filed Japan, the United States, South Korea and other countries Patent) 5. regenerative braking circuit (BRD) is built models expand (22kW or less) 6. equipped with EMC noise filter 7. Built zero-phase reactor installation DCL meet the requirements of the National Transport Shape 8 . With long-life parts, fans, capacitors and other components product life more than 10 years, the life diagnostic function will issue a life warning signal. Before receiving the signal failure for repair 9. Analog input disconnection detection function 10. Intelligent input terminal response time setting 11. intelligent input terminals pulse read 12. PLC programmable function --1024 step 13. The terminal block is omitted costs SJ300 series with interchangeable. ? WJ200 series of excellent control performance and more convenient operation of small inverter * superior speed sensorless vector control to achieve high start-up torque than 0.5Hz / 200% of * significantly reduces the volatility at low speeds than conventional models * reduced 1/2 * Trip Suppression Overexcitation function overcurrent suppression function * equipped with simple position control function * to drive the induction motor / PM motors * Implemented user specifically to run user programmable function * equipped with an emergency stop function for easier corresponding to European machinery instruction, low-cost compliance with safety standards * Long life design equipped with life diagnostic function * Micro-surge voltage suppression function expansion * * bus network wiring and external port corresponds to a simple screwless terminal blocks zero distance space-saving installation * Built-in filter equipped with a variety of functional specification 2-fold amount of the cumulative power monitor function fulfilling the full range of external output monitoring system equipped with a built-in brake circuit "between the inverter communication function (EzCOM)" rich display global certification CE, UL, C- UL, C-TICK, ISO-9001, ISO14001
