2.2 List of parameters
Description: Displays the speed setpoint for the I component of the speed controller (output of the reference model after the
setpoint limiting).
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Refer to: r1438
Note: In the standard state (the reference model is de-activated), r1438 = r1439.
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).
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)
Description: Sets the smoothing time for the actual speed of the speed controller for encoderless closed-loop speed control.
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).
