■
Alarm code 43 (Regenerative Overload)
 Corrective actions
* If the setting of system parameter ID03 “Regenerative Resistor Selection” is incorrect,
regeneration overload is not detected properly, and the amplifier and surrounding circuit may be
damaged or burnt.

Issued when control power supply is turned ON.
✔
Issued when main circuit power supply is turned ON. ✔ ✔ ✔ ✔ ✔ ✔
Issued during operation.
✔ ✔ ✔ ✔
Cause Investigation and corrective actions
1
■
Exceeds a permitted value of the
regenerative power at built-in
regenerative resistance model.
■
Excessive load inertia moment, or
tact time is short.
■
Check the load and operating
conditions.
■
Change to external regenerative
resistor.
■
Set to be the load inertia moment
within the specified range.
■
Increase the deceleration time.
■
Increase the tact time.
2
■
Regenerative resistor is connected
to the model without regenerative
resistor.
■
Remove regenerative resistor.
3
■
Resistor wiring is wrong at built-in
or external regenerative resistor
model.
■
Check the wiring conditions and
correct it if improper.
4
■
Regenerative resistor wire breaks.
■
For built-in regeneration resistor
specifications, replace the servo
amplifier.
■
For external regeneration resistor
specifications, replace the
regeneration resistor.
5
■
Resistance value of external
regenerative resistor is excessive.
■
Replace to the resister that
matching the specifications.
6
■
Input power supply voltage
exceeds the specified range.
■
Check the input power supply
voltage level.
7
■
Defect in internal circuit of servo
amplifier.
■
Replace the servo amplifier.
8
■
External regenerative resistor does
not connect although "02:
External_R" is set in the system
parameter ID03 "Regenerative
resistor selection".
■
Connect external regenerative
resistor.
■
Set "00: Not_connect" in the
system parameter ID03
"Regenerative resistor selection".
Status at the time of alarm
Cause

Cause Investigation and corrective actions
1
■
The average speed exceeds the
maximum speed of continuous
rotation speed range.
■
Review the operating conditions.
■
Resize the servo motor.
