Basic Functions
54 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
DB31, ... DBX94.2 (ramp-up completed)
The signal indicates that the actual speed value has reached the new setpoint allowing for the tolerance band set
in the drive machine data.
The acceleration procedure is thus completed. Any subsequent speed fluctuations due to load changes will not
affect the interface signal.
DB31, ... DBX94.3 (|M
d
| < M
dx
)
The signal indicates that the actual torque |M
d
| is less than the parameterized threshold torque M
dx.
The threshold torque is entered as a percentage of the current speeddependent torque limitation.
DB31, ... DBX94.4 (|n
act
| < n
min
)
The signal indicates that the actual speed |n
act
| is less than the set minimum speed n
min.
DB31, ... DBX94.5 (|n
act
| < n
x
)
The signal indicates that the actual speed |n
act
| is lower than the set threshold speed n
x.
DB31, ... DBX94.6 (n
act
= n
set
)
The PLC is signaled that the actual speed n
act
has reached the new setpoint allowing for the tolerance band set
in the drive machine data and continues to remain within the tolerance band.
