Caution: For p0491 = 1.4 the following must be carefully observed:
In spite of the motor encoder fault that has occurred, the motor is still operated.
Note: For a value 1, 2, 3, the following applies:
Encoderless operation must have been commissioned.
Refer to the status signal "sensorless 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 the original data set (e.g. p1300 = 21). Sensorless
closed-loop controlled operation is kept when changing over.
For sensorless operation (p1404 = 0 or p1300 = 20), the following applies:
- The following condition must be fulfilled: p1800 >= n / (2 * p0115[0]), n = 1, 2, ...
- For motors with a small power rating (< 300 W) we recommend to set n >= 2.
Description: Sets the behavior for the ENCODER fault response (motor encoder).
This means, for example, if an encoder fault occurs, sensorless operation can be automatically selected with a
shutdown behavior that can be selected.
Values: 0: Encoder fault results in OFF2
1: Enc fault results in sensorless oper. and oper. continues
2: Encoder fault results in sensorless operation and OFF1
3: Encoder fault results in sensorless operation and OFF3
4: Encoder fault results in an int. armature short-cct. / DC brake
Dependency: The following parameters are relevant for sensorless operation.
Refer to: p0341, p0342, p1470, p1472, p1517, p1612, p1755
Refer to: F07575
Caution: For p0491 = 1.4 the following must be carefully observed:
In spite of the motor encoder fault that has occurred, the motor is still operated.
Note: For a value 1, 2, 3, the following applies:
Encoderless operation must have been commissioned.
Refer to the status signal "sensorless operation due to a fault" (BO: r1407.13).
Not possible for separately excited synchronous motors (p0300 = 5).
Description: Maximum permissible speed difference between two computation cycles when evaluating square-wave encoders.
When the value is exceeded, depending on p0491, either sensorless closed-loop speed/torque control is selected
or the drive is powered-down.
