Schneider Altivar 312 Inverter, ATV312 is a family of inverters developed by electric-schneider with powerful features with frequency range from 0 to 500Hz, capacity 0.18 to 15Kw with many functions such as: Motor thermal protection, auto-start function, load-speed auto-start function, reversing function, braking function, remote control connection function.
Today plc247.com will write a tutorial for you to use HMI Proface GP4402WW to control Schneider ATV312 through Modbus RTU RS485 Communication.

Schneider ATV312 VFD Communication Setting
In order for the inverter to be controlled by Modbus RTU, we need to set the communication parameters as follows:
- “CON” Menu
+ Add: 1 (Slave Address= 1)
+ tbr: 9.6 (Baudrate = 9600bps)
+ tF0: 8E1
+ tt0: 3.0 (Comm. timer check Error)
- “CtL” Menu
+ LAC: L3
+ Fr1: Mdb (Modbus)
+ Fr2: Mbd
+ CHCF: SEP
+ Cd1: Mbd
+Cd2: Mbd
Register Address Table
Note: GP4402WW HMI Address = “400001 (dec) + Device Address”
>>> Motor Control Address = 400001+ 8501 = 408502
+ Set Word 408502 = 128 : VFD Fault Reset
= 6 : VFD System Start
= 15 : Motor Forward Run
= 2063 : Motor Reverse Run
= 4111 : Stop
>>> Frequency Reference Address = 400001 + 8502 = 408053
>>> Output Frequency Address = 400001 + 3202 = 403203
>>> Output Current Address = 400001 + 3204 = 403205
Proface HMI Modbus RTU Configuration
We need to set the communication parameters the same as those set in the Schneider ATV312
