P1130[2] : 3rd. Drive data set (DDS)
Note:
-
If short or zero ramp times (P1120, P1121 < P1130, P1131, P1132, P1133) are set, the total ramp up
time (t_up) or ramp down time (t_down) will not depend on P1130.
-
See equations above for valid conditions to calculate t_up and t_down.
-
Rounding times are recommended, since they prevent an abrupt response, thus avoiding detrimental
effects on the mechanics.
-
Rounding times are not recommended when analog inputs are used, since they would result in
overshoot/undershoot in the inverter response.
