Frequency misalignment at current input
16.8 mA is output from DCS (16.8 mA is also measured at the inverter terminal) and input to the inverter.
At this time, the inverter's running frequency should be 48 Hz but 50 Hz is displayed.
What can be the cause of this? Let me know the countermeasure.

Answer
It seems that calibration of the current input is slightly incorrect.
By using Pr.904 (Frequency setting current bias) and Pr.905 (Gain), you can calibrate the current input exactly with the actual current.
Perform calibration (setting) using Pr.905 while the actual current is flowing.
