Schneider Altivar 312 inverter (ATV312) is a family of inverters developed by Schneider Electric with powerful features, with a frequency range of 0 – 500Hz, with a capacity of 0.18 – 15Kw.
Compatible with various communication standards: CANopen Daisy Chain, DeviceNet, Profibus DP, Modbus RTU. Today plc247.com will guide you to use Kinco HMI to control ATV312 inverter using Modbus RTU protocol.
HMI Kinco & Schneider ATV312 “Wiring Diagram”
+ The HMI model I use is Kinco MT4414TE, using COM.0 port (RS485-2 wire) other models have RS485 port, you have the same connection.
Schneider ATV312 Modbus Parameters Setting
In addition to the basic parameters of the inverter installed according to the motor (frequency, voltage, current …) then to be able to control and monitor the inverter by Modbus-RTU we need to install additional following parameters.
+ “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
Schneider ATV312 Registers Address
Note: HMI Kinco Holding Registers Address =
“VFD Address (Dec) + 1“
+ VFD Control Address = 8501 + 1 = 8502 (dec)
- Set Word “8502” = 128 : VFD Fault Reset
= 6 : VFD System Start
= 15 : Forward Run
= 2063 : Reverse Run
= 4111 : Stop
+ Frequency Setting Address = 8502 + 1 = 8503 (dec)
+ Output Frequency Address = 3202 + 1 = 3203 (dec)
+ Output Current Address = 3204 + 1 = 3205 (dec)
+ Output Torque Address = 3205 + 1 = 3206 (dec)
HMI Kinco “Modbus RTU” Configuration
We need to set the communication parameters for the Kinco HMI to be the same as those of the Schneider ATV312 inverter.
