Check and correct
the function code.
Check and correct
the register number.
Check the display for
the Digital Operator
and correct the error
data.
Perform write opera-
tions after stopping
the Inverter.
Perform write opera-
tions after clearing
the UV (main circuit
undervoltage) error.
After constant initial-
ization (n001 = "8" or
"9") has been per-
formed, turn the
power supply OFF
and ON again.
Check and correct
the register number.
