NOTE
• Use the retry function only when the operation can be resumed after resetting a protective function activation. Making a retry
against the protective function, which is activated by an unknown condition, will lead the inverter and motor to be faulty. Identify
and remove the cause of the protective function activation before restarting the operation.
• If the retry function operates during PU operations, the operating conditions (forward/reverse rotation) are stored, and
operations resume after retry reset.
• Only the fault details for the first fault that occurred during retry are stored in the fault history.
• When the parameter storage device fault (E.PE) is occurring and reading of the retry-function-related parameters is not
possible, retry cannot be operated.
• Changing the terminal assignment using Pr.195 (Output terminal function selection) may affect the other functions. Set
parameters after confirming the function of each terminal.
