Infeed
2.2 Smart Infeed
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 Smart Line Module
The Smart 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.
