Detailed Description: |
Payment Method: T/T Hoist electric control equipment system input supply voltageAC660V frequency 50 hz Voltage allowed range - 15% ~ + 15% Frequency allowed range + / - 2.5% 1、Control system: consists of PLC1, complete hoist control and protection functions。 A) complete ascension machinist, maintenance and operation mode control. B) complete hoist logic control and atresia. C) to complete the operation of the drive system control and speed is given. D) and the promotion of the control of signal system and blocking each other. 2、Monitoring system: consists of PLC2, its position detection with shaft encoder USES a separate one A) for the trip as the independent variable speed drive system is given, to complete the position control. B) automatic generation of position, velocity envelope curve, complete hoist speed monitoring. C) required by the complete hoist two-wire system volume, speed, speed, reduction and protection functions. D) and the location of the main control system PLC1 output signal and speed signal comparison respectively, two sets of the operation of the PLC system monitoring function. E) to form a circuit software security, and with other security circuit redundancy and atresia. f) in the main control systemPLC1 failure, can be done to improve control. Technical parameters: 1, AC660V input supply voltage, frequency 50 hz; Voltage allowed range - 15% ~ + 15%; Frequency allowed range + / - 2.5%; 2, the output frequency range of 0 ~ 50 hz continuous adjustable; 3, the rated output power: 400 kw 4, overload capacity IN two minutes, 1.5 2 IN a minute. 5, have higher power factor COS Φ > 0.98; 6, the vector control, the low frequency operation, can guarantee the output torque of 200%; 7, inverter with overvoltage, undervoltage, over current, overload, power device motor overheating and lack of equal protection, there is the function of fault memory, can retain recent 10 fault and the last time the function of the number of parameters; 8, the total harmonic content < 5%. |
