To configure the response for extended shutdown, proceed as follows:

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.

Extended retract

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.

To configure the response for extended retraction, proceed as follows:

1. Configure the retract response with p0888 = 2.

2. Define the retraction speed with parameter p0893.
