Regenerative
brake resistor" setting value error.
Built-in regenerative brake resistor
or regenerative brake option is not
connected.
High-duty operation or continuous
regenerative operation caused the
permissible regenerative power of
the regenerative brake option to be
exceeded.
Power supply voltage is abnormal.
(260VAC or more)
Permissible regenerative power
of the built-in regenerative brake
resistor or regenerative brake
option is exceeded.
Regenerative brake option faulty.
