8.11 Extended stop and retract
Drive functions
578 Function Manual, 11/2017, 6SL3097-4AB00-0BP5
In the case of a fault, the objective is to stop the drive in a defined fashion. The stopping
method is used as long as the drive is still capable of functioning. The function is
parameterized and operates on an axis-specific basis. Axes are not coupled.
Configuring the "Extended stop" response
1. Configure the stopping response with the parameter setting p0888 = 1 (N-set) or p0888 =
4 (N-actual).
2. Set the time in parameter p0892 for which the last setpoint from r1438 and the last actual
value from r0063 are frozen before braking is initiated.
3. Select the OFF ramp with parameter p0891.

In the case of a fault, the objective is to approach a retraction position. The retraction method
is used as long as the drive is still capable of functioning. The function is parameterized and
operates on an axis-specific basis. Interpolating coupling of the axes is not realized.
Configuring the "Extended retract" response
1. Configure the retract response with p0888 = 2.
2. Define the retraction speed with parameter p0893.
