4.4.24.2 Blockade reaction
When the blockade reaction is finished, it is immediately change back to "standard"
operation (without internal ramps or straightening).
If this is not desired, an error can be set at the end of the blockade reaction (pa-
rameterization of bit 7...9 "error").
Whether a change of the setpoint speed should have an influence on the blockade
reaction can be parameterized in pn87[1] blockage mode.
The internally effective setpoint speed during the blockade and the current / torque
limits can also be defined here.

The behaviour of this setting depends on the selec-
tion in bit 11,12 "Blockade reaction speed setting":
With the "no speed reduction" setting, the internal
setpoint is frozen at the start of the blockade. The
current/torque limits are not affected.
For all other settings, the torque limit is set equal to
the actual set torque at the start of the blockade re-
action.
The internal setpoint speed is decelerated to zero
during pn87[4] blockade reaction time

time
Same behavior as with "save actual torque".
But after the pn87[4] blockage reaction time has ex-
pired, the change to "blockage reaction finished"
occurs.

linear
torque ramp
A detected blockage is break down with a linear
torque ramp.
For this the torque limit is decremented linearly to
zero.
With Parameter pn87[5] lower limit reduce the re-
duction of the torque limit can be limited to pn87[5]
* dr09 rated torque.
The ramp is not affected by this setting, the torque
limit is just not lowered further.
The drive changes to the state "blockage reaction
finished" at the end of pn87[4] blockage reaction
time.
4
linear cur-
rent ramp
A detected blockage is break down with a defined
linear current ramp.
For this the total current limit is decremented line-
arly to zero.
With parameter pn87[5] lower limit reduce the re-
duction of the torque limit can be limited to pn87[5]
* dr03 rated current.
The ramp is not affected by this setting, the torque
limit is just not lowered further.
The drive changes to the state "blockage reaction
finished" at the end of pn87[4] blockage reaction
time.
