Alarm Code 54 (Built-in Regenerative Resistance Overheat)
 Corrective actions
* When using a regenerative resistor built in the servo amplifier, make sure to set “01:
Built-in_R“ at the system parameter ID03 “Regenerative Resistor Selection”. This setting decides
enabled/disabled of the overheating protection detection treatment of the built-in regeneration
resistance.
* Built-in regenerative resistance overheat does not detected when “02 External_R“ is selected.
Therefore, there is a danger that built-in regenerative resistance will burn out or be damaged.
Status at the time of alarm
Cause
1 2 3
Issued when control power supply is turned
ON.
✔ ✔
Issued during operation.
✔ ✔ ✔
Cause Investigation and corrective actions
1
■
Defect in internal circuit of servo
amplifier.
■
Replace the servo amplifier.
2
■
Regenerative power excessive.
■
Check the built-in regenerative
resistor allowable power.
■
Check the operating conditions to
keep that consumption power is
below of allowable power.
■
Use an external regenerative
resistor.
3
■
Resistor wiring is wrong at built-in
regenerative resistor model.
■
Check the wiring conditions and
correct it if improper.
