Default
FLY-CATCH
ENABLE
VF
Enables flycatching in Volts/Hz control mode when
TRUE. Allows the drive to catch a spinning load.

FLY-CATCH
ENABLE
SV
Enables flycatching in Sensorless Vector control
mode when TRUE. Allows the drive to catch a
spinning load.

SLIP COMP
ENABLE
VF
Slip compensation is operational when TRUE.
Eliminates motor speed variations under load
conditions in V/F Fluxing Mode when the correct
value for MAG CURRENT is entered into

STABILISATION
ENABLE
VF
Enables the stabilisation function when TRUE.
Eliminates light load speed variations in V/F

VOLTAGE
CONTROL MODE
VF
NONE : no attempt is made to control the PWM
modulation depth for variations in dc link voltage
FIXED : the drive's output volts are maintained,
regardless of variations in the dc link voltage. The
drive's product code sets the default value for
demanded maximum output voltage (see MOTOR
VOLTAGE below)
AUTOMATIC : the drive performs controlled over-
fluxing during motor deceleration
0=NONE
1=FIXED
2=AUTOMATIC
0
BOOST MODE
F VF
Determines the relationship between fixed boost
and terminal volts. There are two settings:
FALSE produces the terminal volts profile shown
below (with Auto Boost set to 0.0 %). In this mode
AUTO BOOST (CL08) should also be set to
provide optimum low speed performance.
TRUE emulates the terminal volts profile provided
by the 601 product. This allows drop in
replacement of the 601 by the 650V. AUTO
BOOST (CL08) has no effect in this
mode.

AUTO BOOST
F M VF
This parameter allows for load dependent, stator
resistance voltage-drop compensation. This
correctly fluxes the motor (under load conditions)
at low output frequencies, thereby increasing
available motor torque.. AUTO BOOST is only
used when BOOST MODE is set to 0.
The value of the AUTO BOOST parameter
determines the level of additional volts supplied to
the motor for 100% load.
Setting the value of AUTO BOOST too high can
cause the drive to enter current limit. If this occurs,
the time taken for the drive to reach operating
speed will be extended. Reducing the value of
AUTO BOOST will eliminate this problem.
