DBX93.6 Speed controller integrator disabled
Edge evaluation: no
Signal state 1 The requested shutdown of the speed controller integrator is active in the drive. The speed controller
has been switched over from the PI to P control response.
Signal state 0 The integrator of the speed controller is enabled. The speed controller functions as a PI controller.

DBX93.7 Pulses enabled
Edge evaluation: no
Signal state 1 The pulses have been enabled for the drive. The axis/spindle can now be traversed.
Signal state 0 The pulses have been disabled for the drive. Therefore, the axis/spindle cannot be traversed.
The pulses are disabled as soon as there is no enable signal (refer to the following diagram).
Further, if the "controller enable of drive" is withdrawn, the drive is stopped with setpoint 0
(regenerative braking).
A timer is started in the drive module and after the configured time has expired:
MD1404 $MD_PULSE_SUPPRESSION_DELAY (timer stage, pulse suppression),
the pulses are inhibited.
If, within this time, the actual speed reaches the shutdown speed:
MD1403 $MD_PULSE_SUPPRESSION_SPEED (pulse suppression),
then at this time, the pulses are inhibited.
If the speed is less than/equal to the speed threshold (MD1403), and if the controller enable of the
drive is withdrawn, then the pulses are immediately suppressed.
Pulse suppression is also triggered if there is no position measuring system ("parking axis" state).
As soon as the pulses are suppressed, then also the interface signals:
DB31, ... DBX61.7 (current controller active)
and
DB31, ... DBX61.6 (speed controller active)
are reset.
