Siemens SINAMICS S120 Function Manual page 37

Note
Under the condition that the drive system was commissioned with STARTER and no
PROFIdrive telegram was activated, the infeed can be switched on by issuing an enable
signal at the EP terminals and a positive signal edge at OFF1 (p0840).
Switching off the Active Line Module
The Active Line Module is switched off by the same procedure used to switch it on, but in the
reverse order. However, there is no precharging at switch off.
Switching off the controller with the OFF1 signal is delayed by the time entered in p3490.
This allows the attached drives to be braked in a controlled manner. Before the infeed is
switched off, the drives connected to the DC link should be in pulse inhibit mode.
