PZD interface hardware assignment incorrect

Description:

The assignment of the hardware to the PZD interface has been incorrectly parameterized.

1: Only one of the two indexes is not equal to 99

2: Both PZD interfaces have been assigned the same hardware

3: Assigned COMM board missing

4: CBC10 has been assigned to interface 1

Motor changeover

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.

Applicable to "Vector" drive type:

To switch 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: motor changeover for four motors

Requirements

● 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)
