Selec VFD Series

P4-08
AVR Function
0: Disabled
1: Always Enable
2: Only Enable during
deceleration
Default : 0
The AVR function ensures that the output voltage of the drive remains stable even in cases where the
system might experience fluctuations in the grid voltage.
P4-09
Energy-efficient
running (EER)
0: Disable
1: Enable
In no-load and low-load conditions, the EER option helps in reducing the energy consumed by the
motor by controlling the output voltage accordingly.
Default : 0

The functional codes above define the relationship between the analogue input signal and the
corresponding variation in the set frequency value. These parameters relate specifically to the AI1
terminal i.e. the AI1 terminal. The P5-00 and P5-02 parameters define the percentage of the input
signal that will be treated as the lower and upper limits for the signal received on the AI1 pin. The P5-
01 and P5-03 parameters on the other hand are the corresponding limits for the set frequency values
that will be mapped to the input signal. Note that P5-01 and P5-03 are defined as percentages of the
Upper Limit Frequency as defined in P0-09. The relation between the AI2 signal and the
corresponding signal has been explained in the graph below. The signal loss threshold denotes the
level below which the system will consider the AI2 signal to be lost.
