16. Regenerative Transistor Error
[Display]
[Description of detected alarm]
[Cause and remedy]
Cause Remedy
The regenerative transistor is
short circuited or damaged.
Turn the power off then on again. If the alarm persists, replace
the servo amplifier.
If the regenerative transistor is short circuited or damaged, fire may be caused. If the
regenerative transistor fault alarm signal is output, turn the power off immediately.
17. Inrush Current Suppression Circuit Trouble
[Display]
[Description of detected alarm]
[Cause and remedy]
Cause Remedy
The servo amplifier is damaged.
Replace the servo amplifier.
Keep the ambient temperature 55
℃
or lower (40
℃
or
below is recommended).
The ambient temperature exceeds
55°C.
Move heat generating bodies near the servo amplifier as far
away as possible.
The power is frequently supplied.
Reduce the frequency of turning the power on/off.
(Reference: once a minute or less)
If this alarm is detected even when the ambient temperature is below 55
℃
, replace the
servo amplifier without attempting operating it.
The regeneration handling transistor built in the servo amplifier
is damaged.
rH3
The circuit inside the servo amplifier which suppresses the inrush
current generated at the power on may be broken.
