Hello friends! Continuing the series of articles using HMI Mitsubishi GT2505-VTBD using Modbus RTU protocol to control different devices, today plc247.com will guide you to use it to control Hitachi inverters.
The model used is the Hitachi NE-S1 inverter (with a built-in RS485 port). I will guide you to use HMI GT2505-VTBD to control it in the simplest and easiest way.

Below are the communication parameters that need to be installed for the inverter so that we can control Hitachi NE-S1 with Modbus RTU.

Note: Mitsubishi GOT2000 Holding Registers Address =
“VFD Address (Dec) + 400001“
Coil Address =
“VFD Address (Dec) + 000001“
+ Frequency Setting Address = 1 + 400001 = 400002
+ VFD Start/Stop Address = 0 + 000001 = 000001
VFD Direction Address = 1 + 000001 = 000002
VFD Error Reset Address = 3 + 000001 = 000004
+ VFD “Ready” Status Address = 16 + 000001 = 000017
VFD “Running” Status Address = 18 + 000001 = 000019
VFD “Alarm” Status Address = 23 + 000001 = 000024
+ Output Frequency Address = 4097 + 400001 = 404098
Output Current Address = 4098 + 400001 = 404099
Output Voltage Address = 4112 + 400001 = 404113

Hello,
I really appreciate your work! Handy tutorial! In my case, I have two controllers, Mitsubishi FX3u and NE-S1 VFD. This Hitachi unit replaced the damaged FR 800 Mitsubishi VFD. So, there were additional problems with the specification of the variables. (For FR VFD, there was a dedicated driver, so the specifications of the variable were different.) Probably, the tutorial with the two controllers will also be helpful.
Best regards
Boleslaw
Look on my website for instructions on connecting the FX3U to the FR-E700 Series
