P0327 – F.S. Current Ramp I/f
Adjustable 0.000 to 1.000 s
Range:
Description:
It defines the time for the I/f current to change from 0 to (0.9 x P0401) at the beginning of the frequency scan (f),
in order to minimize the generation of transients in the motor. The factory value varies according to the motor and
is defined by:
P0327 = P0412/8
P0328 – Flying Start Filter
Adjustable 0.000 to 1.000 s
Range:
Description:
It defines an amount of time that allows eliminating the transients generated by the machine during the identification
of the motor speed.
The factory value varies according to the motor and is defined by:
P0328 = (P0412/8 + 0.015 s)
P0329 – Frequency Ramp I/f F.S.
Adjustable 2.0 to 50.0
Range:
Properties: Sless
Access groups 01 PARAMETER GROUPS
via HMI:
Description:
It defines the rate of frequency variation used in the motor speed search.
The factory value of P0329 shown in the following table allows the operation of the function and must be optimized;
normally the final value adjusted is greater than the value suggested.
