2.2 List of parameters
Notice: Regarding the terminal designation:
The first designation is valid for CU320, the second for CU310.
To select the values:
For CX32, NX10 and NX15, only DI/DO 8, 9, 10, 11 can be selected as fast inputs (refer to the Equipment Manual).
Note: DI/DO: Bidirectional Digital Input/Output
The terminal must be set as input (p0728).
Refer to the encoder interface for PROFIdrive.
If parameterization is rejected, check whether the terminal is already being used in p0580, p0680, p2517 or p2518.
p0491 Motor encoder fault response ENCODER / Fault resp ENCODER
VECTOR_G Can be changed: T
Data type: Integer16
P-Group: Encoder
Not for motor type: -
Min
0
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.
Value: 0:
1:
2:
3:
4:
5:
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.
For a value = 1, 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, 5 the following applies:
- Refer to the status signal "encoderless operation due to a fault" (BO: r1407.13).
- if, with r1407.13 = 1, 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.
- not possible for separately excited synchronous motors (p0300 = 5).
For a value = 4, the following applies:
- the value can only be set for all motor data sets when p1231 = 3, 4.
- For synchronous motors, an armature short circuit is initiated on an encoder fault.
- For induction motors, DC braking is initiated on an encoder fault. DC braking must be commissioned (p1232,
p1233, p1234).
For a value = 5, the following applies:
Same function as for value = 1.
However, faults are output as alarm and the message bit "Fault active" (r2139.3) is not set. The encoder fault has to
be acknowledged via the encoder interface in order to resume operation with encoder.
