Cause : Topology: More than two partial lists created. Partial lists are available more than twice in p0978. After the second 0, all must be 0.

Alarm value (r2124, interpret decimal):

Index of p0978 under which the illegal value is located.

Remedy: Set p0009 to 1 and change p0978:

Rules:
- p0978 must include all of the drive object numbers (p0101).
- it is not permissible for a drive object number to be repeated.
- by entering a 0, the drive objects with PZD are separated from those without PZD.
- only 2 partial lists are permitted. After the second 0, all values must be 0.
- dummy drive object numbers (255) are only permitted in the first partial list.
