V/F SHAPE LINEAR : This gives a constant flux characteristic
up to the BASE FREQUENCY
FAN : This gives a quadratic flux characteristic up
to the BASE FREQUENCY. This matches the load
requirement for fan and most pump applications

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.
NORMAL DUTY: the current limit is set to 110%
motor current, inverse time delay is set to 10s
When
P
11 is changed from FAN to LINEAR,
P

set to 0 (HEAVY)
When
P

set to 1 (NORMAL)
P

FIXED BOOST 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
