The Inverter can be set to restart and reset fault detection after a fault
occurs. The number of self-diagnosis and retry attempts can be set to up
to 10 in n082. The Inverter will automatically restart after the following
faults occur:
OC (overcurrent)
OV (overvoltage)
The number of retry attempts is cleared to 0 in the following cases:
1. If no other fault occurs within 10 minutes after retry
2. When the FAULT RESET signal is ON after the fault is detected
3. When the power supply is turned OFF
Operating a Coasting Motor without Tripping
To operate a coasting motor without tripping, use the SPEED SEARCH
command or DC injection braking at startup.
SPEED SEARCH Command
Restarts a coasting motor without stopping it. This function enables
smooth switching between motor commercial power supply operation
and Inverter operation.
Set a Multi-function Input Selection (n050 to n056) to 14 (SEARCH
command from maximum output frequency) or 15 (SEARCH command
from set frequency).
Build a sequence so that a FWD (REV) RUN command is input at the
same time as the SEARCH command or after the SEARCH command.
If the RUN command is input before the SEARCH command, the
SEARCH command will be disabled.
