Actual speed smoothing time / n_act T_smooth

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
0.00 [ms]
Description: Sets the smoothing time constant (PT1) for the speed actual value.
Dependency: Refer to: r0063
Notice: Smoothing times above 20 ms are only possible if the drive is accelerated or braked with the appropriately long ramp-
up/ramp-down times. Otherwise, significant torque errors can occur and there is the danger that the drive is powered
down (tripped) with F07902 (motor stalled).
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
controller settings checked Kp (p1460) and Tn (p1462).
p1442[0...n] Speed controller speed actual value smoothing time / n_ctr n_act T_smth
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
0.00 [ms]
Description: Sets the smoothing time for the actual speed value of the speed controller for closed-loop control with encoder.
Note: The smoothing must be increased if there is gear backlash. For longer smoothing times, the integral time of the
speed controller must also be increased (e.g. using p0340 = 4).
r1443 CO: Speed controller speed actual value at actual value input / n_ctrl n_act inp
VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
- [rpm]
Description: Displays the speed actual value at the speed controller's free-wiring actual value input p1440.
Dependency: Refer to: p1440
Note: This speed signal is only used by the speed controller and not by the motor model.
r1444 Speed controller speed setpoint steady-state (static) / n_ctrl n_set stat
VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
- [rpm]
Description: Displays the sum of all speed setpoints that are present.
The following sources are available for the displayed setpoint:
- setpoint at the ramp-function generator input (r1119).
- speed setpoint 1 (p1155).
- speed setpoint 2 (p1160).
- speed setpoint for the speed pre-control (p1430).
- setpoint from DSC (for DSC active).
- setpoint via PC (for master control active).
