A2: Various NC/PLC interface signals and functions
1.2 NC/PLC interface signals
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
The signal indicates that the actual torque |M
The threshold torque is entered as a percentage of the current speed­dependent torque limitation.
DB31, ... DBX94.4 (|n
The signal indicates that the actual speed |n
DB31, ... DBX94.5 (|n
The signal indicates that the actual speed |n
DB31, ... DBX94.6 (n
act
The PLC is signaled that the actual speed n
in the drive machine data and continues to remain within the tolerance band.
