Active parameter set A, B, C
Signal(s) to drive (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Meaning The drive signals back to the PLC which drive parameter set is presently
active.
With bit combinations A, B and C, 8 different drive parameter sets can be
selected.

Drive ready
Signal(s) to drive (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 Feedback signal from the drive to the PLC that the drive is ready.
Signal state 0 The drive is not ready.
The drive might be disabled for the following reasons:
●
Drive alarm active (e.g. motor temperature has reached switch-off
threshold).
● DC link voltage is too low.
●
Drive has not yet reached the cyclic state.
● Hardware fault present.
● No position measuring system is active ("parking axis" state).
● I/R is not switched on.
As soon as the drive is not ready, it is stopped (depending on the fault state
either with pulse disable or fast stop) or pulses remain disabled while pow‐
ering up.
The interface signals:
DB2700 DBX2.6 (drive ready)
DB390x DBX1.7 (current controller active)
DB390x DBX1.6 (speed controller active)
are also withdrawn.
