FALSE - CONSTANT: Inverse time allows
150% overload for 60s, then ramps back the
current limit to 105% over a 10s period. At a
lower load, the overload area remains the
same, e.g. at 127.5% load for 120s - after
120s has expired, the output of the inverse
time function is ramped back over a 10s
period from 150% as before.
TRUE - QUADRATIC: current limit is set to
110% motor current, inverse time delay is set
to 30s
