2.2 List of parameters
Description: Sets the damping of a PT2 element for the reference model of the speed controller.
Recommendation: The reference model is correctly set when the characteristics of r52154 (reference model output) and r52167 (actual
speed value) are virtually identical when the I component of the speed controller is disabled.
Dependency: In conjunction with p50237 and p50239, the characteristics (in time) of the P-controlled speed control loop can be
emulated.
Refer to: p50237, p50239
Description: Sets the "fractional" dead time for the reference model of the speed controller.
This parameter emulates the computing dead time of the proportionally controlled speed control loop.
The multiplier set refers to the speed controller clock cycle.
Recommendation: The reference model is correctly set when the characteristics of r52154 (reference model output) and r52167 (actual
speed value) are virtually identical when the I component of the speed controller is disabled.
Dependency: In conjunction with p50237 and p50238, the characteristics (in time) of the P-controlled speed control loop can be
emulated.
Refer to: p50237, p50238
Description: Setting to activate the influence of the reference model for the speed controller.
Value: 0: Reference model not effective
1: Reference model effective
Dependency: Refer to: p50241
Description: Sets the signal source for the input signal of the reference model for the speed controller.
Dependency: Refer to: p50240
