Individual steps when restarting:
● After the line supply returns and the electronics has booted, the faults that have occurred
● The faults of the DO x_Infeed are acknowledged via the connection r1214.3 => p2105.
● The ON command (p0840) for the infeed is generated via the binector output "control line
● The power-on attempt is interrupted if, during the new power-on sequence, a fault occurs
● The automatic restart of the DOs x_Infeed have absolutely no significance for the

Motor changeover

11.3.1

Description

The motor changeover is used in the following cases, for example:
● Changing-over between different motors and encoders
● Switching over different windings in a motor (e.g. star-delta switchover)
● Adapting the motor data
If several motors are operated alternately on a Motor Module, a matching number of drive
data sets must be created.
Note
To switch to rotating motor, the "flying restart" function must be activated (p1200).
NOTICE
When changing over the drive data set between several motors that physically exist with
integrated holding brakes, it is not permissible that the internal brake control is used.
