p2533[0...n] LR position setpoint filter time constant / s_set_filt T
CU250D-2_PN_F Access level: 1
CU250D-2_DP_F
Can be changed: U, T
Unit group: -
Min
0.00 [ms]
Description: Sets the time constant for the position setpoint filter (PT1).
Note: The effective Kv factor (position loop gain) is reduced with the filter. This allows a softer control behavior with
improved tolerance with respect to noise/disturbances.
Applications:
- reduces the pre-control dynamic response.
- jerk limiting.
p2534[0...n] LR speed pre-control factor / n_prectrl fact
CU250D-2_PN_F Access level: 1
CU250D-2_DP_F
Can be changed: U, T
Unit group: -
Min
0.00 [%]
Description: Setting to activate and weight the speed pre-control value.
Value = 0 % --> The pre-control is de-activated.
Dependency: Refer to: p2535, p2536, r2563
Note: When the axis control loop is optimally set as well as a precisely determined equivalent time constant of the speed
control loop, the pre-control factor is 100%.
p2535[0...n] LR speed pre-control balancing filter dead time / n_prectrFlt t_dead
CU250D-2_PN_F Access level: 1
CU250D-2_DP_F
Can be changed: U, T
Unit group: -
Min
0.00
Description: Sets the "fractional" dead time to emulate the timing behavior of the speed control loop.
The selected multiplier refers to the position controller clock cycle (deadtime= p2535 * p0115[4]).
Dependency: Refer to: p2536
Notice: When speed pre-control is active (p2534 > 0 %), the following applies:
In addition to the set dead time (p2535), internally two position controller clock cycles are effective.
When speed pre-control is inactive (p2534 = 0 %), the following applies:
No dead time is effective (p2535 and internal).
Note: Together with p2536, the timing behavior of the closed-loop control loop can be emulated.
p2536[0...n] LR speed pre-control symmetrizing filter PT1 / n_prectrl filt PT1
CU250D-2_PN_F Access level: 1
CU250D-2_DP_F
Can be changed: U, T
Unit group: -
Min
0.00 [ms]
Description: Sets a PT1 filter to emulate the timing behavior of the closed-speed control loop.
Dependency: Refer to: p2535
Notice: When speed pre-control is inactive (p2534 = 0 %), the following applies:
If a PT1 filter has been set, it is not effective.
Note: Together with p2535, the timing behavior of the closed-loop control loop can be emulated.
