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.

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

Hitachi NES1 Registers Address Mapping
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
