Description
This parameter is valid only on axes with custom feedback on the primary and/or secondary input. This parameter provides options to automatically set the No Transducer or Prs/Frc No Transducer error bit. The following options are available:
Missed Update
If the Custom Counts register is not written to in a given loop time, the No Transducer error will be set. This is the preferred mode for most applications. In this mode, you should make sure that the Custom Counts register is written to each loop time.
PROGRAM Mode
If the controller is in PROGRAM mode, the No Transducer error will be set. This mode may be useful in situations where you do not need to update the Custom Counts very often, but you do wish to halt the axis if the program that updates the Custom Counts is stopped due to the controller entering PROGRAM mode.
Disabled
The No Transducer error will not be set by any of the above options. In this mode, the updating of the Custom Counts register is not monitored in any way. This could be used in cases where the Custom Counts register is being modified from an external device, such as a PLC.
The No Transducer Error bit can still be set by using the No Transducer and Secondary No Transducer bits in the Custom Error Bits register. Additionally, if the Custom Counts is NaN, INf, -Inf, the No Transducer error bit will also be set.
Format Details
The Custom Feedback Auto-Fault Mode is selected with bits 0-3. These bits correspond to the Auto-Fault Mode as shown in the following table:
