Figure 1-9
Note
Under the condition that the drive system was commissioned with STARTER and no
PROFIdrive telegram was activated, the infeed can be powered-up by issuing an enable
signal at the EP terminals and a positive signal edge at OFF1 (p0840).
Switching off the Basic Line Module
To switch off the Active Line Module, carry out the steps for switching it on in reverse order.
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.
