Under which conditions will the DCTRL1-RDY signal (¨Ready to operate¨) be deactivated?
Question:
Under which conditions will the DCTRL1-RDY signal ('Ready to operate') be deactivated by the processor of the frequency inverter?
Answer:
While the frequency inverter is ready to operate the DCTRL1-RDY signal is activated by the processor (HIGH level). This signal will be deactivated (LOW level) if an overvoltage message (OU), low voltage message (LU) or a TRIP occurs. The DCTRL1-RDY signal is also deactivated while the frequency inverter is initialised.
