• 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. (This is different from
power supply reset or reset by RES signal.)
• When the parameter storage device fault (E.PE) is occurring and reading of the retry-function-related parameters is not
possible, retry cannot 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.
• When the retry function is set enabled, stay away from the motor and machine in the case of an output shutoff. The motor
and machine will start suddenly (after the reset time has elapsed) after the shutoff. When the retry function is selected,
apply the supplied CAUTION stickers to easily visible places.
Parameters referred to
Pr.57 Restart coasting
This function is used in case of emergency such as a fire to forcibly continue inverter operation to drive a motor without
activating protective functions even if the inverter detects a fault. Using this function may cause damage of the motor or the
inverter because driving the motor is given the highest priority. Use this function for emergency operation only. When the
inverter is damaged by a fault, the motor operation can be continued by switching to the commercial power supply operation.
