Determining the drive object numbers

Further information about the drive system (e.g. drive object numbers) can be determined as

follows using parameters p0101, r0102, and p0107/r0107:

1. The value of parameter r0102 ("Number of drive objects") for drive object/axis 1 is read

2. Depending on the result of the initial read request, further read requests for drive object 1

3. Following this, parameter r0107/p0107 ("Drive object type") is read for each drive

4. From here, refer to the parameter list for each drive object.

via a read request.

Drive object 1 is the Control Unit (CU), which is a minimum requirement for each drive

are used to read the indices for parameter p0101 ("Drive object numbers"), as specified

by parameter r0102.

If the number of drive objects is "5", the values for indices 0 to 4 for parameter p0101 are

read. Of course, the relevant indexes can also be read at once.

The first two points provide you with the following information:

• How many drive objects exist in the drive system?

• The numbers of the existing drive objects

object/axis (indicated by the drive object number).

Depending on the drive object, parameter 107 can be either an adjustable or visualization

The value in parameter r0107/p0107 indicates the drive object type. The coding for the

drive object type is specified in the parameter list.
