Notes On The Number Of Controllable Drives; Number Of Drives Depending On The Control Mode And Cycle Times - Siemens SINAMICS S120 Function Manual

Basic information about the drive system

Note
Incorrect SI status display
If a drive in a Safety Integrated drive line-up is deactivated using p0105, then r9774 is not
correctly output. The signals of a deactivated drive are no longer updated.
Activating/deactivating components
Drive objects can be activated/deactivated using parameter p0105 and encoders with
p0145[0...n] in the Expert list in the same way. If a component is not required at certain times,
then for the component, change parameter p0105 or p0145 from "1" to "0". The deactivated
components remain inserted, however, they are deactivated. Errors are not displayed from
deactivated components.

Notes on the number of controllable drives

14.12.6.1

Number of drives depending on the control mode and cycle times

The number of axes that can be operated with a Control Unit depends on the cycle times and
the control mode. The number of usable axes and the associated cycle times for each control
type are listed below. The other available remaining computation times are available for options
(e.g. DCC).
