For MT8071iE Modbus RTU: HMI Address = “VFD Address + 1”
>>> Control Address = 8501 + 1 = 8502
- Set 8502(hex) = 6 >>> Enable Operation
- Set 8502(hex) = 128 >>> Reset Fault
- Set 8502(hex) = 15 >>> Forward Run
- Set 8502(hex) = 2063 >>> Reverse Run
- Set 8502(hex) = 4111 >>> Stop
>>> Frequency Reference Address = 8502 + 1 = 8503
ATV312 Register Monitoring
- System Ready = 3201 + 1 = 3202 (bit00), Alarm Present (bit07)
- Output Frequency = 3202 + 1 = 3203
