Fault Retry (n48)
The Inverter may be break if the fault retry function is used.
If the Inverter breaks, take the following measures:
Be sure to install a no-fuse breaker (NFB).
Provide the Inverter and peripheral machines with a sequence so that the
machines will stop operating when the Inverter has an operational fault.
• The fault retry function automatically resets and restarts the Inverter in the
case the Inverter has an overvoltage fault, overcurrent fault, or ground
fault.
• In the case of any other fault, the protective function operates instantly
and the fault retry function does not operate.
• This function is to be used only if the user does not want to interrupt the
mechanical system, even if this function may damage the Inverter.
• Set n40 for multi-function output to the following value so that external
overtorque detection output will be turned on.
Set value: 14 for fault retries
Set Values
• Set the number of fault retries required.
• The count of fault retries will be cleared in any of the following cases.
The Inverter is normal for 10 minutes continuously after the latest fault retry
was made.
Power supply to the Inverter is interrupted.
A fault reset is input.
