The different characteristics are described in Technical manual.

Pickupx: Operate phase current level for step x given in % of IBase.

tx: Definite time delay for step x. The definite time tx is added to the inverse time when inverse

time characteristic is selected.

TDn: Time multiplier for inverse time delay for step n.

IMinn: Minimum operate current for step n in % of IBase. Set IMinn below Pickupx for every step to

achieve ANSI reset characteristic according to standard. If

IMinn is set above Pickupx for any step

the ANSI reset works as if current is zero when current drops below

IMinn.

tnMin: Minimum operate time for all inverse time characteristics. At high currents the inverse time

characteristic might give a very short operation time. By setting this parameter the operation time

of the step can never be shorter than the setting. Setting range: 0.000 - 60.000s in steps of

0.001s.
