Note: In the standard state (the reference model is de-activated), r1438 = r1439.
Description: Displays the speed setpoint after setpoint limiting for the P component of the velocity controller.
For V/f operation, the value that is displayed is of no relevance.
Dependency: Refer to: r1439
Note: In the standard state (the reference model is de-activated), r1438 = r1439.
Description: Displays the speed setpoint for the I component of the speed controller (output of the reference model after the set-
point limiting).
Dependency: Refer to: r1438
Note: In the standard state (the reference model is de-activated), r1438 = r1439.
Description: Displays the velocity setpoint for the I component of the velocity controller (output of the reference model after the
setpoint limiting).
Dependency: Refer to: r1438
Note: In the standard state (the reference model is de-activated), r1438 = r1439.
Description: Sets the smoothing time constant (PT1) for the speed actual value.
Dependency: Refer to: r0063
