dtS Tacho Coeff. 1 to 2 1
Multiplication coefficient of the feedback associated with the tachogenerator function:
dtS =
9
tachogenerator voltage at max. speed HSP
ENGLISH
rPG PI Prop.Gain 0.01 to 100 1
PI regulator proportional gain
rIG PI Int. Gain 0.01 to 100/s 1/s
PI regulator integral gain
FbS PI Coeff. 1 to 100 1
PI feedback multiplication coefficient
PIC PI Inversion no - yes no
Reversal of the direction of correction of the PI regulator
no: normal yes: reverse
Ftd Freq.Lev.Att - Hz LSP to HSP 50 Hz
Motor frequency threshold above which the logic output changes to 1
F2d Freq.2 Att - Hz LSP to HSP 50 Hz
Frequency 2 threshold: same function as Ftd, for a 2nd frequency value
Ctd Curr.Lev.Att - A 0 to 1.1 In (1) 1.1 In (1)
Current threshold above which the logic output or the relay changes to 1
ttd ThermLev.Att - % 0 to 118% 100%
Motor thermal state threshold above which the logic output or the relay changes to 1
PSP PI Filter - s 0.0 to 10.0 0 s
Used to adjust the filter time constant on the PI feedback
PI2 PI Preset 2 - % 0 to 100% 30%
2 nd preset PI reference, when a logic input has been assigned to the 4 preset PI references function.
100% = process max 0% = process min
PI3 PI Preset 3 - % 0 to 100% 60%
3 rd preset PI reference, when a logic input has been assigned to the 4 preset PI references function.
100% = process max
0% = process min
dtd ATV th.fault 0 to 118% 105%
Drive thermal threshold above which the logic output or the relay changes to 1
(1) In corresponds to the drive nominal current indicated in the catalogue and on the drive rating plate.
The parameters with a grey background appear if an I/O extension card has been installed.
