Signals from axis/spindle (DB31, ...)

DB31, ...
DBX95.0 VDC link < alarm threshold
Edge evaluation: No
Signal state 1 The drive signals that the DC link voltage VDC link is lower than the "lower DC link voltage
threshold" set using parameter p1248".
Signal state 0 The drive signals that the DC link voltage VDC link is greater than the "lower DC link voltage
threshold" set in the drive using parameter p1248".
Application The PLC user program can initiate measures in order to safely end machining and/or to buffer the
example(s) DC link voltage (e.g. initiate a drive-integrated and/or control-managed ESR).
corresponding to ... Drive parameter p1248 (lower DC link voltage threshold)

DBX95.3 Generator operation – minimum speed fallen below
Edge evaluation: No
Signal state 1 The axis is parameterized as generator axis. The drive signals that the actual speed is less than the
minimum speed set using parameter p2161 (speed threshold value 3).
Signal state 0 The axis is parameterized as generator axis. The drive signals that the actual speed is greater than
the minimum speed set using parameter p2161 (speed threshold value 3).
Application The PLC user program can initiate measures in order to safely end machining and/or to buffer the
example(s) DC link voltage (e.g. initiate a drive-integrated and/or control-managed ESR).
