3VFD-E inverter PLC law implementation compilation

The upload and download of the PLC Fadu is implemented through the PLC2 programming page. Press the MODE key to the "PLC0" page, then press the up button to switch to "PLC2", then press "ENTER", the success will show "END", and then it will jump back to "PLC2". Note that the inverter is in a deterrent shape before uploading and downloading the Fadu.

There are three types of PLC methods for the implementation of VFD-E inverter:

The first preparation: under the PLC1 programming page, actively implement the PLC method;

The second type of preparation: under the PLC2 programming page, the WPL is worked by the communication PLC law (implementation/containment);

The third type of preparation: terminal work preparation. When the external multi-function input terminals (MI3-MI9) are set to "RUN/STOPPLC(99)", PLC1 is displayed on the PLC screen when the terminal contacts are turned on (close), and the PLC law is implemented. When the terminal contact is open (open), PLC0 will be displayed on the PLC page to stop the PLC law.

4. The special function of the built-in PLC is installed and set up, and it is equipped with a paving statement

Limited space, this article is only a statement of commonly used special relays and registers, etc., and you can see the imitation list of VFD-E series downloaded from the website of Zhongda Dentsu Co., Ltd. in detail.

4.1 Special Relay Statement

M1000 works normally open contact (A contact). In RUN, there is always On, a contact. RUN, this contact is On

M1001 works with normally closed contact (B contact). RUN is always off, b contact. In the shape of RUN, this contact is off

M1005 inverter fault

The M1006 has zero output frequency

M1007 Inverter Working Target Intent FWD(0)/REV(1)

M1025 Inverter RUN(ON)/STOP(OFF)

M1026 Inverter Working Object Intent FWD(OFF)/REV(ON)

M1028 High-Speed Counting Function (ON) / Closed (OFF)

4.2 Special Register Function Statement

D1025 High-Speed Counter (Low)

D1025 High-Speed Counter (High Position)

4.3 Inverter special instructions

1DHSCS High-Speed Counting Function Statement:

DHSCSS1S2S3 (S1: specific force value; S2: high-speed counter number; S3: Specific force effect. )

The function of high-speed pulse counting requires the PG card to complete the external pulse input.

By setting the policy value required by the DHSCS directive and turning on the M1028 (special function relay, the function is the inverter high-speed counting function ON/OFF), the count will be actively performed. If you want to have a root break counter, you need to set M1029 (a special function relay with a high-speed root break count value) to ON.

The high-speed counter has 3 types of motion control and can be set by the special register D1044.

The first form is the form of "A-B phase pulse". The input of the counter is made using pulses that can pass through the input A phase and B phase, and the demand is adjacent to the GND.

The second form is the form of "pulse + symbol". The user can manipulate the input of the pulse and the symbols to make the upper or lower counts. It is said that phase A is used for pulses, phase B is used for symbols, and the demand and GND are shorted.

The third form is the "pulse + sign bit" form. In the counting compilation, the upper or lower number can be judged by the sign bit M1030, so the user knows that the demand is adjacent to phase A, and the demand and GND are shorted.

2FPID inverter PID control.

　　FPIDS1S2S3S4

Where: S1

ID refers to the input terminal selection of the policy (0-4);

　　S2

ID share gain P(0-100);

　　S3

ID points moment I (0 - 10000);

　　S4

ID Differential Time D (0 - 10000).

3FREQ inverter working control.

　　FREQS1S2S3

Where: S1: set the frequency; S2: acceleration moment; S3: Slowdown time.

For example: FREQK5000K200K100

THEN: SET THE POLICY FREQUENCY TO 50HZ, THE ACCELERATION TIME IS 20S, AND THE DECELERATION TIME IS 10S

4RPR inverter parameter reading.

　　RPRS1S2

Here: S1: reference numerical address; S2: Keeps the read parameters in S2.

5WPR inverter parameter write.

　　WPRS1S2

In this case, S2 is the address of the parameter, and the parameter value S1 is written to the parameter S2.
