2.2 List of parameters
Description:
Sets the smoothing time for the actual speed value of the speed controller for closed-loop control with encoder.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
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).
Description:
Displays the speed actual value at the speed controller's free-wiring actual value input p1440.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1440
Note:
This speed signal is only used by the speed controller and not by the motor model.
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 precontrol (p1430).
- setpoint from DSC (for DSC active).
- setpoint via PC (for master control active).
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: r1119, p1155, p1160
Description:
Display and connector output for the actual smoothed speed actual value of the speed control.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
