DBX21.6 Speed controller integrator disable
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
The interface signal is used by the 611D/611U to disable the integrator of the speed controller.
The speed controller is thus changed over from a PI to a P controller.
Note:
If the speed controller integrator disable is activated, equalization processed might take place in
certain applications (e.g. if the integrator was already holding a load while stationary).
The drive acknowledges the integrator disable to the PLC using the interface signal:
DB31, ... DBX93.6 (speed controller integrator disabled).
Signal state 0 or
edge change
1 → 0
The integrator of the speed controller is enabled.
Corresponding to ... DB31, ... DBX93.6 (integrator n-controller disabled)

DBX21.7 Pulse enable
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
Pulse enable is signaled by the PLC for this drive (axis/spindle).
The pulses for the drive modules are only enabled if all enable signals are available (see DB31, ...
DBX93.5).
In this case, the following is signaled to the PLC:
DB31, ... DBX93.7 = 1 (pulses enabled)
For additional information refer to DB31, ... DBX93.7
Signal state 0 or
edge change
1 → 0
The pulses are disabled by the PLC for this drive.
If pulse enable is canceled for a moving axis/spindle the axis/spindle is not longer braked in a
controlled fashion. The axis coasts to rest.
Application
example(s)
Signal relevant to safety
Special cases,
errors, ....
If pulse enable is canceled for a moving axis/spindle as a result of an Emergency Stop, the axis/
spindle only coasts to rest.
Corresponding to ... DB31, ... DBX93.7 (pulses enabled)
