Individual steps when restarting:
● After the line supply returns and the electronics has booted, the faults that have occurred

at DO vector as a result of its automatic restart are acknowledged depending on the

settings in p1210.

● 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

contactor" of the DO vector (p0863.1).

● The power-on attempt is interrupted if, during the new power-on sequence, a fault occurs

on the DO x_Infeed. The fault is communicated to the DO vector via the BICO connection

p1208.0 => r2139.3 shown above.

● The automatic restart of the DOs x_Infeed have absolutely no significance for the

described power-on version.

11.3

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.

11.3.2

Example: motor switchover for four motors

Prerequisites:

● The drive has been commissioned for the first time.
● 4 motor data sets (MDS), p0130 = 4
