2.6.4.1. Overview
The Solardrive Plus software controls the motor according to the IFD (Voltage/Frequency Control) algorithm,
where the output voltage is computed based on frequency and special parameterization.

2.6.4.3. Parameters for IFD control
This group of parameters
defines the V/f pattern trend of the drive when it is used as an IFD control
algorithm. When setting the type of V/f pattern (
C013
), the following curves can be used:
•
Constant torque
•
Quadratic
•
Free setting
The diagram below illustrates three types of programmable curves compared to the theoretical V/f curve.
If
C013 = Constant Torque,
Preboost parameter
C034
allows changing the starting voltage value if
compared to the theoretical V/f curve (this allows torque compensation for losses caused by the stator
impedance and a greater torque at lower revs).
If
C013 = Quadratic,
the drive will follow a V/f pattern with a parabolic trend. You can set the starting voltage
value (
C034
), the desired voltage drop if compared to the relevant constant torque (use
C032
) and the
frequency allowing implementing this torque reduction (use
C033
).
If
C013 = Free Setting,
you can
program the starting voltage (
C034 Preboost
), the increase in voltage to
1/20 of the rated frequency (
C035 Boost0
), and the increase in voltage (
C036 Boost1
) at programmable
frequency (
C037 Frequency for Boost1
).
