Status

The status bits indicate warnings and errors:

  • Process image 3: Voltage min error
    Error message in case of undervoltage.
    This bit is TRUE if the supply voltage US is lower than CoE index 8000:11 "Voltage min error limit" (unit: mV).
    Requirement: CoE parameter 8000:02 "Enable voltage min error" is TRUE.
  • Process image 4: Voltage max error
    Error message in case of overvoltage.
    This bit is TRUE if the supply voltage US is higher than CoE parameter 8000:12 "Voltage max error limit" (unit: mV).
    Requirement: CoE parameter 8000:03 "Enable voltage max error" is TRUE.
  • Process image 5: Current max error
    Error message in case of overcurrent.
    This bit is TRUE if the output current IS is higher than CoE parameter 8000:13 "Current max error limit" (unit: mA).
    Requirement: CoE parameter 8000:04 "Enable current max Error" is TRUE (default).
  • Process image 6: Voltage min warning
    Warning message in case of undervoltage.
    This bit is TRUE if the supply voltage US is lower than CoE parameter 8000:14 "Voltage min warning limit" (unit: mV).
    Requirement: CoE parameter 8000:05 "Enable voltage min warning" is TRUE (default).
  • Process image 7: Voltage max warning
    Warning message in case of overvoltage.
    This bit is TRUE if the supply voltage US is higher than CoE parameter 8000:15 "Voltage max warning limit" (unit: mV).
    Requirement: CoE parameter 8000:06 "Enable voltage max warning" is TRUE (default).
  • Process image 8: Current max warning
    Warning message in case of overcurrent.
    This bit is TRUE if the output current IS is higher than CoE parameter 8000:16 "Current max warning limit" (unit: mV).
    Requirement: CoE parameter 8000:07 "Enable current max warning" is TRUE (default).
  • Process image 9: Channel error
    This bit is TRUE if at least one status bit of "EPM Inputs Channel 1" that signals an error message is TRUE:
       Voltage min error
       Voltage max error
       Current max error
  • Process image 10: Channel warning
    This bit is TRUE if at least one Status bit of "EPM Inputs Channel 1" that signals a warning message is TRUE:
       Voltage min warning
       Voltage max warning
       Current max warning
  • Process image 11: TxPDO State
    This bit is TRUE if an internal error occurs. The current measured values of "EPM Inputs Channel 1" are invalid if this bit is TRUE.
  • Process image 12: TxPDO Toggle
    This bit is inverted on each update of the measured values.
