Note: This P gain (Kp) is effective up to x coordinate 1 (p50556).
The adaptation of the P gain (Kp) is defined using 2 pairs of values.
Pair of values 1:
p50556/p50550 (x/y coordinate)
Pair of values 2:
p50559/p50225 (x/y coordinate)
Description: Sets the y coordinate for pair of values 1 for adaptation of the integral time (Tn).
Note: This integral time (Tn) is effective up to x coordinate 1 (p50557).
The adaptation of the integral time (Tn) is defined using 2 pairs of values.
Pair of values 1:
p50557/p50551 (x/y coordinate)
Pair of values 2:
p50560/p50226 (x/y coordinate)
Description: Sets the y coordinate for pair of values 1 for adaptation of the droop.
Notice: - For the droop, generally values up to 10 % are practical (p50552 = 0.000 ... 0.100). Under certain circumstances,
higher values can result in an unstable response of the speed controller.
- The droop is entered as absolute factor without any dimensions and it is especially important to note that it is not a
percentage.
Example:
Set droop = 5 % --> p50552 = 0.05
Note: This droop is effective up to x coordinate 1 (p50558).
The adaptation of the droop is defined using 2 pairs of values.
Pair of values 1:
p50558/p50552 (x/y coordinate)
Pair of values 2:
p50561/p50227 (x/y coordinate)
Description: Sets the signal source for the P gain (Kp) on the speed controller.
