This parameter can drift by as much as 0.8% over the lifetime of this product.
This parameter can drift by as much as 1% over the lifetime of this product.
See page 8 on how to set overcurrent fault switchpoint.
Switchpoint can be lower at the expense of switchpoint accuracy.
This error specification does not include the effect of noise. See the I
Fault Enable Delay is designed to avoid false tripping of an Overcurrent (OC) fault at power-up. A 15 μs (typical) delay will always be needed, every
