MOTOR

(Continued)
CNTL BASE SPEED
(1602)
Preset Value: Motor Rated Speed (P2403)
Range: 0 - MAX Speed RPM
The speed at which Field Weakening begins.
CNTL BASE VOLT
(1611)
Only available or active in V/F
mode. Ignore this parameter
for Vector modes.
Preset Value: CALC
Range: 0 - Drive Rated Voltage
The voltage output to the motor at Control Base Speed (P1602). Typically set to
motor rated voltage.
STATIC BOOST
(1612)
Only available or active in V/F
mode. Ignore this parameter
for Vector modes.
Preset Value: 0.0
Range: 0.0 - 15.0%
Additional voltage applied to motor at start-up.
DYN BOOST CUTIN
(1613)
Only available or active in V/F
mode. Ignore this parameter
for Vector modes.
Preset Value: 30.00
Range: 6.00 - 60.00 Hz
Speed at which dynamic boost takes full effect.
DYNAMIC BOOST
(1614)
Only available or active in V/F
mode. Ignore this parameter
for Vector modes.
Preset Value: 0.0
Range: 0.0 - 10.0%
The Dynamic Boost parameter can be adjusted to provide more or less running
torque from the motor than is available with the factory setting. The boost
adjustment alters the output voltage to the motor from the normal voltage value
by increasing or decreasing the voltage per frequency unit as defined by the V/F
profile.
V/F EFFICIENCY
(1615)
Only available or active in V/F
mode. Ignore this parameter
for Vector modes.
Preset Value: 0
Range: 0 -1
Off (0) Smoothing disabled.
On (1) Smooting enabled.
Smooths transitions between static boost and V/F curve.
V/F PROFILE
(1616)
Only available or active in V/F
mode. Ignore this parameter
for Vector modes.
Preset Value: 0.0
Range: 0.0 - 100.0%
0 = Linear
100 = Quadratic
Set the Volts/Frequency ratio of the control output (to the motor) for all values of
output voltage versus output frequency up to the control base frequency. Because
motor voltage is related to motor current, motor voltage can then be related to
motor torque. A change in the V/F profile can adjust how much torque is available
from the motor at various speeds.
