It is associated with the power-frequency fan current
detection and overload protection functions. It is valid
only when the value is not 0, and it is invalid when the
value is 0.
Setting range: 0–40.0
Setting range: 1.0–4000.0
When ratio of the maximum current to the minimum
current among the fan three-phase currents is greater
than this value, the VFD reports the fan current
unbalance fault.
Setting range: 1.00–3.00
Actual current = Displayed current * Current coefficient
