Delta converter built-in PLC function application principle – inverter, plc, Delta – Electrical indu by hi joiney
Abstract: This article discusses the inverter’s epoch-making products?? PLC embedded inverter. By introducing the Delta VFD-E Series inverter, display inverter cutting-edge technology. Keywords: converter built-in PLC embedded integrated 1 Introduction In the vast majority of Frequency Control engineering applications, require external auxiliary electromechanical transducer together to achieve the automatic control system Of operation. External mechanical and electrical control system associated with the different requirements of the ever-changing target speed, and sometimes can be quite complex, cases As the most common mechatronic motion systems, the project will have on the inverter and PLC integration of joint control of the regular run. Delta VFD-E (Figure 1) series inverter integrated in the internal embedded programmable controller. VFD-E for the mechanical and electrical integration Complex speed control system to create a compact total solution time. Figure 1 Delta VFD-E Series Inverter 2VFD-E converter built-in PLC Introduction ? PLC progressive scan standard operating mode. Rich programming language: instruction statement; ladder; SFC. Rich command statement: Directive 45 categories, including 28 basic instructions, application instructions 17. 350 step program capacity. ? US-level basic instruction processing speed. ? End of the regeneration of the input / output control method (when END command execution when the input and output are immediately refresh command). 8 basic points I / O Configuration: 6 input points (X), 2 output points (Y). I / O module extensions: The I / O cards can be configured nine input, 4 output points. Common auxiliary relay M: 160 points. (M0-M159, a total of 32 special with the relay M1000-M1031) Timer: 16. T0 ~ T15 (100ms). ? Counter: 8 16-bit (C0 ~ C7); 1 32 (C235). General internal register D: 30 points (D0 ~ D29) Special registers D: 45 points. (D1000 ~ D1044). Mainly as a storage system status, error messages, monitoring. Through the RS485 programming. 3VFD-E Inverter PLC program execution PLC program upload and download programming through PLC2 page execution. First press MODE button to “PLC0″ page, then click on the button to switch to “PLC2″, then press “ENTER”, success will display “END”, then jump back to the “PLC2″. In the absence of download to the inverter which Before, if you can ignore the warning. Note that in the upload and download process is stopped before the inverter state. Implementation of the VFD-E converter internal PLC program in three ways: First approach: program page in PLC1, the automatic implementation of the PLC program; Second way: in PLC2 programming page, and through WPL PLC by the communication control program run (run / stop); Third way: terminal operation mode. When multi-function input terminal for external (MI3-MI9) is set to “RUN / STOPPLC (99)”, the terminal contacts conduction (close) when the page is displayed in the PLC PLC1, implementation of the PLC program. Terminal junction circuit (open) when the PLC page will show the PLC0, stop the PLC program. 4 built-in PLC special function device configuration instructions To space limitations, this article just used the special relays and registers, explain, in detail can be seen in up to Dentsu Inc. web site to download VFD-E series of instructions. 4.1 Special Relay Description M1000 running monitor normally open contacts (a contact). RUN often when On, a contact point. RUN the state, the contacts On M1001 surveillance operation normally closed contacts (b contact). RUN often when Off, b contacts. RUN the state, the junction Off M1005 inverter fault indication M1006 output frequency to zero M1007 inverter operation direction FWD (0) / REV (1) M1025 Inverter RUN (ON) / STOP (OFF) M1026 inverter operation direction FWD (OFF) / REV (ON) M1028 high-speed counting function is activated (ON) / closed (OFF) 4.2 Special Function Registers D1025 high-speed counter present value (low) D1025 high-speed counter present value (high) 4.3 inverter special instructions 1DHSCS high-speed counting function: DHSCSS1S2S3 (S1: comparison value; S2: High-speed counter number; S3: Comparison of the results.) High-speed pulse counting with PG card required to achieve external pulse input. DHSCS instructions from the set target value needed, and the M1028 (special function relays, high-speed counting function is to open the inverter ON / OFF) to open, will automatically be counted. If you want to clear the counter value, you need to M1029 (special function relay function is to clear the high-speed count) is set to ON. High-speed counter with three kinds of motion control mode, you can set special register D1044. First model is the “AB phase pulse” mode. Use can enter the A phase and B-phase pulse input counter to do, needs, and GND connection. The second model is “pulse + sign” model. Users can use the input pulse and by the number of symbols to do on or with a few. A similar impulse to do the definition, B, do sign, needs, and GND shorted. Third model is the “pulse + flag” mode. In counting mode, you can flag M1030 to judge by the number or lower number, so users need to know can be a connection A phase, needs, and GND shorted. 2FPID Inverter PID control. FPIDS1S2S3S4 Including: S1: PID reference target selection input terminal (0 to 4); S2: PID proportional gain P (0 ~ 100); S3: PID integral time I (0 ~ 10000); S4: PID differential time D (0 ~ 10000). 3FREQ inverter operation control. FREQS1S2S3 Including: S1: set the frequency; S2: acceleration time; S3: deceleration time. Example: FREQK5000K200K100 Is: set a target frequency is 50HZ, acceleration time is 20S, 10S deceleration time is 4RPR inverter parameters read. RPRS1S2 One: S
