Basic parametrization for Delta VFD-E Series Inverters for Modbus communications. This inverter was factory reseted and configured to receive commands and frequency adjustments through the RS-485 port available in the front panel (RJ-45 connector).
---
Summary of basic parameters:
00:02 Reset Inverter - 10 (factory reset - was used only for this test, not necessary)
02:00 Master frequency command - 3 (RS-485 communication)
02:01 Source of first operation command - 3 (RS-485 communication)
09:00 Communication Address - 4 (Modbus slave address 4)
09:01 Communication Speed - 2 (19200 bps)
09:04 Communication Protocol - 3 (Modbus RTU 8-N-2)

Can I change the amplitude of output by rs485 ? I need decrease the amplitude of output with my PLC.

[@ProfGustavoKikee]

Hi! If I remember correctly, you can actually change the frequency (rotating speed) by setting the register 0x2001 value of the VFD Inverter. If you set the register value as 3000 (decimal), you will have 30 Hz. If you set register the register value to 6000 (decimal), you will have 60 Hz.
You can also set different ramps in the IHM of the inverter and set the 0x2000 command register properly.
I recommend reading the manual for more information.
Cheers

​@@ProfGustavoKikeebuongiorno le chiedo gentilmente se mi può dire come impostare i parametri che il mio motore funziona al massimo degli giri con inverter Delta vdf ,i dati del motore sono 267hz 4000 giri ,grazie in anticipo

Do you know how to change the address on manual (ex: 2102, 2103) to some usable address on modscan?

[@ProfGustavoKikee]

Hey Daniel! I'm not sure this can be done in the VFD parameters.
But remember to check in Modscan if the addresses must be inserted in decimal or hexadecimal mode (ex 2102 is in hex = 8450 in decimal).
Cheers

@@ProfGustavoKikee I already checked in the modscan, I can read the frequency but I can't write the freq.

Hi! I conducted some experiments lately in my classes. Check this information:
- The register to set the vfd frequency is (Holding Register) 0x2001 (8193 in decimal);
- The function 0x06 (Write Single Register) should be used to set the frequency;
- The value written in the holding register represents the desired frequency*100. For example:
- To set the frequency to 30 Hz, you should write the value 3000 (in decimal) to the holding register 0x2001;
- To set the frequency to 60 Hz, you should write the value 6000 (in decimal) to the holding register 0x2001;
Modbus RTU example:
If the slave address configured in the vfd is 01 and you want to set the frequency to 60 Hz (6000 decimal or 0x1770), the bytes sent to set frequency should be
0x01 0x06 0x20 0x01 0x17 0x70 CRC-L CRC-H
