19.1 Various interface signals and functions (A2)
DB31, ...
DBX92.1 Ramp-function generator disable active (feedback)
Edge evaluation: No
Signal state 1 Ramp function generator fast stop is active for the drive.
Signal state 0 Ramp function generator fast stop is not active for the drive.
Application exam‐ Position controller bypassing of the ramp function generator.

Corresponding to ... DB31, ... DBX20.1 (ramp-function generator fast stop)
Remark In the SINAMICS a protocol can be set that runs in what is known as the 611U compatibility mode.

DBX92.4 Drive-autonomous motion active
Edge evaluation: No
Signal state 1 A drive-autonomous motion is active.
The axis traverses due to setpoints created by drive-internal functions. The drive still responds to
control signals of the NC, e.g. controller enable. Setpoint specifications of the NC are ignored.
Signal state 0 A drive-autonomous motion is not active.
Application exam‐ Internal drive functions:
ple(s)
● Rotor or pole position identification
● Function generator
Remark DBX92.4 = 1 IF MELDW.11 == 1 (controller enable) AND ZSW1.2 == 0 (operation enabled)

DBX93.0 - DBX93.4 Motor/drive data set: Display interface
Edge evaluation: No
Meaning The active motor data set (MDS) and drive data set (DDS) are displayed via the interface.
Formatting the request interface, i.e. which bits are used to address the motor data sets (MDS) – and
which are used to address the drive data sets (DDS) is set via the formatting interface.
Remark For main spindle drives:
● MDS[ 0 ] → star operation
● MDS[ 1 ] → delta operation
Corresponding to ... DB31, ... DBX21.0 - 4 (motor/drive data set: request interface)
DB31, ...DBX130.0 - 4 (motor/drive data set: formatting interface)
DB31, ... DBX21.5 (motor being selected)
