FALSE - HEAVY DUTY: Inverse time allows 150%
overload for 30s, 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 60s - after 60s has expired, the output of
the inverse time function is ramped back over a
10s period from 150% as before.
TRUE - NORMAL DUTY: current limit is set to
110% motor current, inverse time delay is set to
30s
When
P
11 is changed from FAN LAW to LINEAR
LAW,
P
12 is set to 0 (HEAVY DUTY)
When
P
11 is changed from LINEAR LAW to FAN
LAW,
P
12 is set to 1 (NORMAL DUTY)
P
12 can be changed independently

FIXED BOOST
M
VF
Used to correctly flux the motor at low speeds. This
allows the drive to produce greater starting torque
for high friction loads. It increases the motor volts
above the selected V/F characteristic at the lower
end of the speed range
