Dependency: Refer to: p0488, p0489, p0493, p0495, p0728
Note: The terminal must be set as input.
When the measuring probe or the equivalent zero mark is inverted, this has no effect on the status displays of the
digital inputs (r0721, r0722, r0723).

Description: Sets the behavior for the ENCODER fault response (motor encoder).
This means, for example, if an encoder fault occurs, encoderless operation can be automatically selected with a
shutdown behavior that can be selected.

Dependency: The following parameters are relevant for encoderless operation.
Refer to: p0341, p0342, p1470, p1472, p1517, p1612, p1755
Refer to: F07575
Caution: For a value = 1, 2, 3, 5 the following applies:
- encoderless operation must have been started.
- if, for synchronous motors, an encoder fault occurs below the switchover speed p1755, when switching over to
encoderless operation, the motor can stall.
For a value = 1, 5 the following applies:
- in spite of the motor encoder fault that has occurred, the motor continues to operate.
Note: For a value = 1, 2, 3, the following applies:
- for encoderless operation the following condition must be fulfilled: p1800 >= n / (2 * p0115[0]), n = 1, 2, etc.
- Refer to the status signal "encoderless operation due to a fault" (BO: r1407.13).
- If, when setting r1407.13, a different drive data set is selected (e.g. interconnection from p0820), then the open-
loop or closed-loop control type p1300 of this data set must match that of the original data set (e.g. p1300 = 21).
Encoderless closed-loop controlled operation is kept when changing over.
For a value = 4, the following applies:
- the value can only be set for all motor data sets when p1231 = 4
- the function is not supported on synchronous motors
- For induction motors, DC braking is initiated on an encoder fault. DC braking must be commissioned (p1232,
p1233, p1234).
