2.2 List of parameters
Description:
Setting to invert the digital input signals to connect a measuring probe or an equivalent zero mark.
Dependency:
Refer to: p0488, p0489, p0493, p0728
Notice:
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).
Regarding the terminal designation:
The first designation is valid for CU320, the second for CU310.
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).
DI/DO: Bidirectional Digital Input/Output
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:
Encoder fault results in OFF2
1:
Enc fault results in encoderless oper. and oper. continues
2:
Encoder fault results in encoderless operation and OFF1
3:
Encoder fault results in encoderless operation and OFF3
4:
Encoder fault results in DC braking
5:
Enc fault results in encoderless op, operation continues, alarm
Dependency:
The following parameters are relevant for encoderless operation.
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.
For a value = 4, the following applies:
- the value can only be set for all data sets when p1231 = 4
- 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.
