Description
Selects which time periods (1...4) are used with timed
function 3. Also determines whether boost is used with timed
function 3.
The parameter is a 16-bit word with each bit corresponding to
a function. Whenever a bit is set to 1, the corresponding
function is in use.
The bits of the binary number correspond to the following
functions:

The bits of the binary number correspond to the following
functions:
Flux reference and U/f curve settings. See also section
U/f curve on page 50.
Sets the flux reference (in percent of parameter
nom freq) at field weakening point.
Flux reference at field weakening point.
Selects the form of the U/f (voltage/frequency) curve below
the field weakening point.
Linear U/f curve. Recommended for constant-torque
applications.
Quadratic U/f curve. Recommended for centrifugal pump and
fan applications.
Custom U/f curve. The curve is formed by the points defined
by parameters 38.04...38.13.
Defines the frequency at the 1st point on the custom U/f curve
in percent of parameter
1st point, frequency.
Defines the frequency at the 2nd point on the custom U/f
curve in percent of parameter
2nd point, frequency.
