ATV312 Inverter is designed powerfully, optimally with frequency range from 0 to 500Hz, capacity 0.18 to 15Kw, applied in many fields: conveyor, packing machine, mixer, water pump, ventilation system, machine crushing, lifting system…ATV312 Altivar with high reliability, meets the operating requirements of simple and complex machines, thereby saving time and improving operational efficiency.
Today plc247.com will guide you to use HMI Mitsubishi GT2505-VTBD to control Schneider ATV312 inverter through Modbus RTU (RS485) communication protocol.
GT2505-VTBD & Schneider ATV312 “Wiring Diagram”
Below is a diagram of Modbus-RTU communication connection between HMI GT2505-VTBD and Schneider ATV312 Inverter
Schneider ATV312 “Modbus RTU” Parameters Setting
To be able to control the Schneider ATV312 inverter, we need to install the following parameters for the inverter
- “CON” – Menu
+ Add = 1 (Slave Address = 1)
+ tbr = 9.6 (Baudrate = 9600bps)
+ tF0 = 8E1 (8bit/even/1bit)
+ tt0 = 3.0 (Comm. timer check Error)
- “CtL” – Menu
+ LAC = L3
+ Fr1 = Mdb (Modbus)
+ Fr2 = Mbd
+ CHCF = SEP
+ Cd1 = Mbd
+ Cd2 = Mbd
Registers Address Mapping
Note: Mitsubishi GOT2000 Holding Registers Address =
“VFD Address (Dec) + 400001“
>>> VFD Control Address = 8501 + 400001 = 408502 (dec)
- Set Word 408502 = 128 : VFD Fault Reset
= 6 : VFD System Start
= 15 : Forward Run
= 2063 : Reverse Run
= 4111 : Stop
>>> Frequency Setting Address = 8502 + 400001 = 408503 (dec)
+ Output Frequency Address = 3202 + 400001 = 403203 (dec)
+ Output Current Address = 3204 + 400001 = 403205 (dec)
+ Output Torque Address = 3205 + 400001 = 403206 (dec)
Mitsubishi HMI “Modbus RTU” Configuration
We need to set the Modbus communication parameters for the HMI to be the same as those set for the VFD
HMI Programming
+ Main Control Panel
+ VFD “Alarm” Status
+ VFD Reset Command
+ VFD “Ready” Status
+ VFD System Start
+ Frequency Setting
+ Forward Run Command
+ Reverse Run Command
+ VFD Stop Command
+ Read Output Frequency
+ Read Output Current
+ Read Output Torque
