Special Parameters
This parameter may be used in the Constant Torque or the Variable
Torque modes only and should be adjusted gradually to improve the
application-specific torque requirements. The Torque Boost setting
(
) may be adjusted to improve the low-frequency torque
performance.
Note:
The Torque Boost setting should be adjusted gradually before
attempting performance corrections using this parameter.

V/f Five-Point 1 Frequency
Program
Special
V/f Five-Point Setting
The V/f Five-Point 1 Frequency setting establishes the frequency that is
to be associated with the voltage setting of
(V/f Five-Point 1
Voltage).
The V/f Five-Point settings define a custom volts per hertz relationship
for the startup output of the ASD.
To enable this function, set the V/f Pattern
(
selection to Custom V/f
Curve.
V/f Curves may be useful in starting high inertia loads such as rotary
drum vacuum filters.
