Alarm Code 56 (Servo Amplifier Temperature Error)
 Overheating detection of Drive module
Status at the time of alarm
Cause
1 2 3 4
Issued when control power is turned ON.
✔ ✔ ✔
Issued at input of servo ON.
✔ ✔ ✔
Issued while starting and stopping the
servo motor.
✔ ✔ ✔
Issued after operation for some time.
✔ ✔ ✔ ✔
 Corrective actions
Cause Investigation and corrective actions
1
■ U/V/W-phase of amplifier is short
circuited due to the wiring in amplifier
and motor.
Or, U/V/W-phases have earth fault.
■
Check the wiring conditions and correct it
if improper.
2
■ Short circuit or earth fault of U/V/W
phases, at servo motor side.
■
Replace the servo motor.
3
■
Defect in internal circuit of servo
amplifier.
■
Replace the servo amplifier.
4
■
Ambient temperature is high.
■
Confirm temperature in cabinet (or
ambient of the amplifier), then refine
installation method of the servo amplifier
and ventilation of the cabinet to keep
55
℃
or lower of ambient temperature.
* This temperature is measured at the point very near to driving module.
It is different from measurement point of temperature monitor for R ADVANCED MODEL (at the
point near to control IC of control board).
■
Alarm Code 61 (Over-Voltage)
 DC Excess voltage of main circuit
Status at the time of alarm
Cause
1 2 3 4
Issued when control power is turned ON.
✔
Issued when main circuit power supply is
turned ON.
✔ ✔
Issued while starting and stopping the
servo motor.
✔ ✔ ✔
 Corrective actions
Cause Investigation and corrective actions
1
■
Defect in internal circuit of servo
amplifier.
■
Replace the servo amplifier.
2
■
The power supply voltage of main circuit
is out of the specification.
■
Reduce the power supply voltage to
within the specified range.
3
■
Excessive load inertia moment.
■ Reduce the load inertia moment to within
the specified range.
4
■
Incorrect wiring of regenerative resistor.
■ Built-in regenerative circuit is not
functioning.
■
Wire the regenerative resistor correctly.
■
Check the wiring and resistance value if
using the external regenerative resistor.
■
Replace the servo amplifier if any
abnormality occurs after countermeasure
above.
