Detailed Description
2.1 Various interface signals and functions (A2)
DB31, ...
DBX93.3 - DBX93.4
Active motor A, B
Edge evaluation: no
Meaning The drive module (611D) returns signals to PLC stating which motor selection is currently active.
Motor selection can be used with a main spindle drive (MSD) to switch between star and delta
operation and so reduce the starting current.
The following assignment applies:
Signal irrelevant for SINUMERIK 810D
...
Corresponding to .... DB31, ... DBX21.3 and DBX21.4 (motor selection)
DB31, ... DBX21.5 (motor selected)

DB31, ...
DBX93.5 Drive Ready
Edge evaluation: no
Signal state 1 or Feedback signal from the drive to the PLC that the drive is ready.

As soon as the drive is ready for operation it is stopped (depending on the fault state either with
pulse disable or fast stop) or pulse disable is maintained during ramp up.
The interface signals:
DB10 DBX108.6 (611D ready)
DB31, ... DBX61.7 (current controller active)
DB31, ... DBX61.6 (speed controller active)
are also withdrawn.
IS "611D Ready" is not available for the 840Di when used in conjunction with the drive 611U.
