Description
When speed error window control (see parameter
Speed error window control
parameter determines whether the speed controller only
observes the proportional term instead of all three (P, I and D)
terms.
All three terms (parameters 25.02,
observed by the speed controller.
Only the proportional term (25.02) is observed by the speed
controller. The integral and derivative terms are internally
forced to zero.
Defines the upper boundary of the speed error window. See
parameter 24.41 Speed error window control
Upper boundary of speed error window.
Defines the lower boundary of the speed error window. See
parameter 24.41 Speed error window control
Lower boundary of speed error window.
Defines an additional speed error step given to the input of
the speed controller (and added to the speed error value).
This can be used in large drive systems for dynamic speed
normalizing.
WARNING! Make sure the error step value is
removed when a stop command is given.
