How can I read the mains voltage of an ATV212 drive over Modbus?
Resolution:
The mains voltage can be monitored using parameter FE04, which is available at Modbus address 65028.
The value returned by FE04 represents the mains voltage as a percentage of the drive's rated voltage.
To calculate the actual mains voltage:
Mains Voltage = (FE04 value ÷ 10,000) × Drive Rated Voltage
For example, on an ATV212...N4 drive rated for 400 V:
- FE04 = 10570
- This corresponds to 105.7% of the rated voltage.
- Mains voltage = 1.057 × 400 V = 422.8 V, or approximately 423 V.
Therefore, an FE04 reading of 10570 on a 400 V ATV212 indicates a mains voltage of approximately 423 V.
