CUSTOM V/F CURVE (1617)
Only available or active in V/F
mode. Ignore this parameter
for Vector modes.
Preset Value: 0
Range: 0 - 2
Off (0) Curve set in parameter “V/F Profile” (P1616).
3 Point (1) Allows two linear V/F segments by setting the V/F 3 Point Volts and V/F 3 Point
Frequency parameters.
7 Point (2) Allows six linear V/F segments by setting the 7-Point voltage and frequency values.
Allows custom V/F Curve profile settings to taylor the V/F Curve to specific
applications for optimum performance. Only available or active when “Control
Type” (P1601) is set to PM V/F Control. Takes precedence over “V/F Profile”
(P1616).

3 POINT VOLTAGE (1618)
Only available or active in V/F
mode. Ignore this parameter
for Vector modes.
Preset Value: 0.0
Range: 0.0 - 100.0%
The output voltage associated with the 3 Point Frequency parameter. Calculated as
a percentage of drive rated output voltage.
3 POINT FREQ (1619)
Only available or active in V/F
mode. Ignore this parameter
for Vector modes.
Preset Value: 30.00
Range: 0.00 - maximum output speed P2003 Hz
The output frequency associated with the 3 Point Volts parameter.
SLIP COMP ENABLE (1620)
Only available or active in V/F
mode. Ignore this parameter
for Vector modes.
Preset Value: 0
Range: 0 - 1
Off (0) Slip compensating disabled.
On (1) Slip compensating enabled.
Compensates for change in slip due to varying load conditions during normal
operation to maintain constant rotor speed.
