Integration time
Defines the integration time of the speed controller. The
integration time defines the rate at which the controller
output changes when the error value is constant and the
proportional gain of the speed controller is 1. The shorter the
integration time, the faster the continuous error value is
corrected. Too short an integration time makes the control
unstable.
If parameter value is set to zero, the I-part of the controller is
disabled.
Anti-windup stops the integrator if the controller output is
limited. See
The figure below shows the speed controller output after an
error step when the error remains constant.
