Ramp-up completed
Signal(s) to drive (NCK → PLC)
Signal(s) updated: Cyclic
The PLC is signaled that after a new speed setpoint input, the speed actual
value has reached the speed tolerance bandwidth and has remained within
this tolerance bandwidth for the specified time.
Even if the speed actual value leaves the tolerance bandwidth (because of
speed fluctuations resulting from load changes) the "ramp-up completed"
signal remains.
The conditions described above have not yet been fulfilled. Ramp-up has
therefore not yet been completed.

The signal only becomes active after ramp-up has been completed (DB390x
DBX4002.2 = 1) and the signal interlock time for the threshold torque has
expired.
The torque setpoint M is greater than the threshold torque M

If necessary, the PLC user program can initiate a response.
