1280*
Following error increase threshold for detecting the fixed stop.
This machine data is only active when MD 1804* bit 4 = 0. The signal "Fixed stop reached" is
set when the following error has been exceeded by the value defined in MD 1280*.
Example:
MD 1280* = 500 = 0.5 mm
Traversing velocity 1000 mm/min
Servo gain factor = 1
The triggering threshold for the fixed stop reached in this example is:
1 mm + 0.5 mm = 1.5 mm
1284*
Zero speed control window in fixed stop.
This data only takes effect when MD 1804*, bit 3 = 1.
If the position at which the fixed stop was triggered is exceeded by more than the tolerance
defined in MD 1284*, travel to fixed stop is aborted with an error message.
1288*
The integral action of the torque compensation controller is parameterized in the integral action
time. The integral action is deactivated if set to the default value 0 because the proportional
action (MD 1384*) already ensures an adequate static distribution of torque.
The additional integral action can produce a better distribution in multi-slave operation.
Practical values are in the region of seconds. See also MD 1812*.
