Speed controller integrator disable
Signal(s) to drive (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 The request from the PLC to disable the integrator of the speed controller
using the interface signal "Speed controller integrator disable" is active for
the drive.
The speed controller has therefore switched from a PI to a P controller.
Signal state 0 The integrator of the speed controller is enabled. The speed controller func‐
tions as a PI controller.

Pulses enabled
Signal(s) to drive (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 The pulse enable for the drive is present. The axis / spindle can now be
traversed.
Signal state 0 The drive pulses are disabled. Therefore, the axis / spindle cannot be trav‐
ersed.
The pulses are disabled as soon as there is no enable signal.
Also,
if the
"controller enable of drive" is withdrawn, the drive is stopped with
setpoint 0 (regenerative braking).
Pulse disable is also triggered if there is no position measuring system
("parking axis" state).
As soon as the pulses are disabled, then the following IS are also reset:
DB390x DBX1.7 (current controller active)
DB390x DBX1.6 (speed controller active)
Application Signal-oriented signal.
Special cases, errors, ... If pulse enable is withdrawn for a moving axis / spindle the axis / spindle is
not longer braked in a controlled fashion. The axis / spindle coasts down.

Ramp-up completed
Signal(s) to drive (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 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.
Signal state 0 The conditions described above have not yet been fulfilled. Ramp-up has
therefore not yet been completed.
