Function modules

Function module

Extended current setpoint filter (r0108.21) In the "Open-loop/closed-loop control" area, extends the "Current setpoint filter"

Position control (r0108.3)

DSC with spline (r0108.6)

Extended stop and retract (r0108.9)

Cogging torque compensation (r0108.22)

Activating function modules

Proceed as follows to activate a function module:

1. Click on the desired function module (e.g. technology controller).

Repeat this step for all additional function modules that you wish to activate.

When the "basic positioner" function module is activated, then the "position control" function

module is automatically activated as well.

2. Save the project to back up the settings.

Overview of important parameters (see SINAMICS S120/S150 List Manual)

● p0108[0..n]

● p0124[0...n]

to include an additional 6 filters.

Allows fault events to be recorded.

In the "Technology functions" area, activates the "Position controller" function.

Also supplements the "Basic parameterization" area to include the "Mechanical

system" function.

In the "Open-loop/closed-loop control" area, extends the interconnection of the

"Speed precontrol" function. Adds the "Dynamic Servo Control" secondary

screen form.

In the "Setpoint channel" area, activates the "Extended stop and retract" function.

In the parameter view, activates all parameters of the "Cogging torque compen‐

sation" parameter group. Cogging torque compensation can only be parameter‐

ized via the parameter view.

The activation of this function module leads to a significant increase in the re‐

quired computing time per drive axis.

The operation of 6 servo axes on one Control Unit can no longer be guaranteed

in all constellations and should be reduced to 5 axes.
