Application
example(s)
As soon as "heatsink temperature prewarning" has been signaled, the PLC can, for example, initiate
controlled shutdown of the drives.

DBX94.2 Ramp-up completed
Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 The PLC is signaled, that after a new speed setpoint has entered, the speed actual value has
reached the speed tolerance bandwidth:
MD1426 $MD_SPEED_DES_EQ_ACT_TOL (tolerance bandwidth for n
set
= n
act
- signal)
and has remained within this tolerance bandwidth for at least the time defined using machine data:
MD1427 $MD_SPEED_DES_EQ_ACT_DELAY (delay time n
set
= n
act
- signal)
refer to the diagram).
Even if the speed actual value leaves the tolerance band (because of speed fluctuations resulting
from changes in load) the "rampup completed" signal remains (1 signal).
Signal state 0 The conditions described above have not yet been fulfilled. The rampup has therefore not yet been
completed.
