Parameters
Parameter list
Dependency: Refer to: r1439
Note: In the standard state (the reference model is de-activated), r1438 = r1439.
r1439 Speed setpoint, I component / n_set I_comp
VECTOR (n/M) Can be changed: -
Data type: Floating Point
P-Group: Control
Min
- [1/min]
Description: Displays the speed/velocity setpoint for the I component of the speed/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.
p1441[0...n] Actual speed smoothing time / n_act T_smooth
VECTOR (n/M) Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
0.00 [ms]
Description: Sets the smoothing time constant (PT1) for the speed/velocity actual value.
Dependency: Refer to: r0063
Note: The speed actual value should be smoothed for encoders with a low pulse number or for resolvers.
After this parameter has been changed, we recommend that the speed controller is adapted and/or the speed con-
troller settings checked Kp (p1460) and Tn (p1462).
p1442[0...n] Actual speed smoothing time / n_act T_smooth
VECTOR (n/M) Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
0.00 [ms]
Description: Sets the smoothing time for the actual speed value for closed-loop control with encoder.
Note: The smoothing must be increased if there is gear backlash. For longer smoothing times, the integral action time of
the speed controller must also be increased (e.g. using p0340 = 4).
r1444 Speed controller, speed setpoint steady-state (static) / n_ctrl n_set stat
VECTOR (n/M) Can be changed: -
Data type: Floating Point
P-Group: Control
Min
- [1/min]
Description: Displays the sum of all speed/velocity setpoints that are present.
The following sources are available for the displayed setpoint:
- setpoint at the ramp-function generator input (r1119).
- speed/velocity setpoint 1 (p1155).
- speed/velocity setpoint 2 (p1160).
- speed/velocity setpoint for speed/velocity pre-control /(p1430).
- setpoint from DSC (for DSC active).
- setpoint via PC (for master control active, p3983).
