Speed controller reference model damping / n_ctrl ref_m d

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.000
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
p50239[0...n]

Speed controller reference model dead time / n_ctr ref_m t_dead

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.00
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

Speed controller reference model activation / n_ctrl ref_m act

DC_CTRL Can be changed: T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description: Setting to activate the influence of the reference model for the speed controller.
Value: 0:

Dependency: Refer to: p50241
p50241 CI: Speed controller reference model signal source / n_ctrl ref_m sig s
DC_CTRL Can be changed: T
Data type: Unsigned32 / FloatingPoint32
P-Group: -
Not for motor type: -
Min
-
Description: Sets the signal source for the input signal of the reference model for the speed controller.
Dependency: Refer to: p50240
