Details
Overvoltage The voltage of the converter in the
servo drive unit was 400V or
more.
Motor overheating An operation state causing the
motor to overheat continued.
Overload 1 The servo drive unit or
servomotor overload protection
function activated.
Overload 2 The max. output current flowed
for several seconds due to a
machine collision or overload.
Excessive error A position deflection exceeding
the excessive error detection
setting value occurred.
Details
Battery voltage The absolute position detection
drop battery voltage dropped.
Over-regeneration The regeneration power may
warning have exceeded the tolerable
range of the built-in regenerative
resistor or external regenerative
option.
