Functions Common to all the Control Modes
12-10 | CFW700
P0327 – FS I/f Current Ramp
Adjustable
Range:
0.000 to 1.000 s Factory
Setting:
0.070 s
Description:
It defines the time for the I/f current to change from 0 to the level used in the frequency sweep (f). It is determined
by: P0327=P0412/8.
P0328 – Flying Start Filter
Adjustable
Range:
0.000 to 1.000 s Factory
Setting:
0.085 s
Description:
It establishes the time of permanence in the condition that indicates that the speed of the motor was found. It
is defined by: P0328=(P0412/8 + 0.015 s).
P0329 – FS I/f Frequency Ramp
Adjustable
Range:
2.0 to 50.0
Factory
Setting:
6.0
Properties: Sless
Access groups
via HMI:
Description:
It defines the rate of frequency variation used in the motor speed search.
P0329 is determined in function of P0404, as showed in the next table:
Table 12.4: P0329 value in function of P0404
P0404 0...20 21...23 24...25
P0329 6.0 7.0 8.0
The frequency variation rate is determined by: (P0329 x P0412).
