11.2 Description

● The switch on attempt is interrupted if, during the restart, a fault occurs in the Infeed

● The automatic restart of the Infeed Module has absolutely no significance for the

X_INF stands for all drive objects "Infeed"; i.e.: A_INF, B_INF, S_INF

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 changeover)

● Adapting the motor data

If several motors are operated alternately on a Motor Module, a matching number of drive

data sets must be created.

For the "Vector" control mode, the following applies:

To connect to a rotating motor, the "flying restart" function must be activated (p1200).

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.

Example of a motor changeover for four motors (encoderless)

Preconditions

● First commissioning has been completed.

● 4 motor data sets (MDS), p0130 = 4

● 4 drive data sets (DDS), p0180 = 4

● 4 digital outputs for controlling the auxiliary contactors

● 4 digital inputs for monitoring the auxiliary contactors

● 2 digital inputs for selecting the data set

● 4 auxiliary contactors with auxiliary contacts (1 NO contact)

Module (drive object X_INF). The fault is communicated to the VECTOR drive object via

the BICO connection from p1208.0 to r2139.3 shown above.
