Only if the ratio Is/Id is higher than the response threshold of the motor protection
function (dr38 SM prot. min. Is/Id) the tripping time (ta) expires.
The tripping time at minimum threshold current is dr35 SM prot.time min. Is/Id and
at maximum current (dr12) dr36 SM prot.time Imax.
A counter is increased. If the counter reaches 100%, the error "14 : ERROR mo-
torprotection“ is triggered.
If the ratio Is/Id < dr38, the counter is decreased with a factor defined by the recov-
ery time (dr37SM prot. recovery time). The prot.recovery time is the time, which the
counter needs to count from 100% to 0%.
The triggered error by the motor protection function can be reset at 98%.
