MAX SPEED
M
The frequency at which the 650V will run when
maximum setpoint is applied. The default is

MIN SPEED
The minimum frequency at which the 650V will
run, as a percentage of the MAX SPEED parameter

FREQUENCY
M
The output frequency at which maximum voltage is
reached. The default is Product Code dependent
7.5 to 240Hz

RUN STOP MODE RAMPED : The motor speed is reduced to zero at a
rate set by DECEL TIME (
P
5). A 2 second DC pulse
is applied at end of ramp
COAST : The motor is allowed to freewheel to a
standstill
DC INJECTION : On a stop command, the motor
volts are rapidly reduced at constant frequency to
deflux the motor. A low frequency braking current
is then applied until the motor speed is almost
zero. This is followed by a timed DC pulse to hold
the motor shaft.

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