Range Off, 5 – 40 % (Default 15%)

Description The Current Imbalance Trip Level parameter sets the imbalance that is allowed before the starter shuts down.

The current imbalance must exist for 10 seconds before a fault occurs.

Current is less than the FLA setting

The equation for the current imbalance is:

( )

%imbalance

Iave I

FLA

max

100

Iave = average current

FLA = value programmed into P1

Current is greater than the FLA setting

The equation for the current imbalance is:

( )

%imbalance

Iave ax

100

Iave = average current

FLA = value programmed into P1

If the highest calculated current imbalance is greater than the current imbalance level for 10 seconds, the

starter shuts down the motor and declares a Fault 37 (Current Imbalance).

See Also Auto Reset Limit (P42 / PFN 11) parameter on page 104.

Controlled Fault Stop Enable (P43 / PFN 12) parameter on page 105.
