Name: Excessive regeneration warning
There is a possibility that regenerative power may exceed permissible regenerative power of built-in
regenerative resistor or regenerative option.
Cause
(1) Permissible regenerative
power of the built-in
regenerative resistor or
regenerative option is
over 85 .
Name: Overload warning 1
There is a possibility that overload alarm (50.1, 51. ) may occur.
Cause
(1) Load is 85 or larger of
the overload alarm (50.1)
alarm level.
(1) Load is 85 or larger of
the overload alarm (50.2)
alarm level.
(1) Load is 85 or larger of
the overload alarm (51.1)
alarm level
(1) Load is 85 or larger of
the overload alarm (50.3)
alarm level.
(1) Load is 85 or larger of
the overload alarm (50.4)
alarm level.
(1) Load is 85 or larger of
the overload alarm (50.5)
alarm level.
(1) Load is 85 or larger of
the overload alarm (51.2)
alarm level.
(1) Load is 85 or larger of
the overload alarm (50.6)
alarm level.
Stop method: Axes can operate (warning
detected at both axes)
Checkpoint
Check the regenerative 85
load ratio with MR
Configurator.
Stop method: Axes can operate (detected at
the corresponding axis)
