Infeed
Basic Infeed
Switching on the Basic Line Module:
Fig. 1-8
Note
Under the condition that the drive system was commissioned with STARTER and
no PROFIBUS 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 re-
verse order.
Switching off the controller with the OFF1 signal is delayed by the time entered in
p3490, thereby allowing the connected drives to be decelerated in a controlled
manner.
