11. (H) Protective Function Parameters
11.7 Retry function
• Writing "0" in
Pr.69
clears the cumulative count.
Selecting retry generating faults (Pr.65)
• Using
Pr.65
, the fault that causes a retry is selectable. The faults not described in the following table do not enable the
retry function. (For the details of faults, refer to the Instruction Manual (Maintenance).)
●
indicates the faults selected for
retry.
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.
• The reset by the retry function does not clear the accumulated data of the electronic thermal O/L relay, regenerative brake
duty, etc. (This is different from power supply reset or reset by RES signal.)
• When the parameter storage device fault (control circuit board) (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.190 to Pr.196 (Output terminal function selection)
may affect the other
functions. Set parameters after confirming the function of each terminal.
