Corrective Measures
Cause Corrective measures
1
Allowable regeneration power
of built-in regenerative resistor
is exceeded.
Load inertia is too large, or
conducted time (for one cycle)
is too short
Review the load inertia and the
operational pattern
Use an external regenerative resistor
module.
Smaller load inertia within specified
range
Increase deceleration time
Increase conducted time
2
Built-in regenerative resistor
module is specified, but faulty
wiring.
Check wrong wiring and correct it.
3
Though external regenerative
resistor module is specified,
wiring is incorrect.
Check wrong wiring and correct it.
4 Faulty regenerative resistor.
Replace servo amplifier if using built-in
regenerative resistor module.
Replace resistor if using external
regenerative resistor module.
5
Resistance value of external
regenerative resistor module is
too large
Change to resistor that meets
specification.
6
Input power voltage is over
specification.
Review input power voltage
7 Faulty amplifier control circuit Replace servo amplifier.
8
Though selecting “Using external
regenerative resistor (02)” in
Page 0E of System Parameter
Regenerative resistor selection, it
is not equipped.
Equip an external regenerative
resistor.
Specify “Regenerative resistor is not
connected”.

Caution
For the setting that internal or external regenerative resistor
is used, detect regenerative error if it is not actually
connected.
For the setting that regenerative resistor is not used,
regenerative error is not detected when it is actually
connected. In other words that may damage or bum the
amplifier and its peripheral circuit.

Cause Corrective measures
1
Faulty internal circuit of Servo
Amplifier
Replace amplifier.
2 Regenerative power is too large
Review operational conditions
Use external regenerative resistor
3
Although regenerative power is
within specification, ambient
temperature of Servo Amplifier is
out of specification.
Review cooling method so that
temperature in control board is from
32°F (0℃) to 131°F (55℃).
4
Though regenerative power is
within specification, the cooling
fun in Servo Amplifier stops.
Check if the cooling fan in amplifier is
rotating. Replace the amplifier if fan is
not operating.
5
Regenerative power when
emergency stoppage was too
large.
Replace Amplifier
Review load condition
Caution
Detect the error by amplifier internal temperature regardless
of ambient temperature. If warning of amplifier ambient
temperature is detected, make sure to review the cooling
method in the control board.

When using regenerative resistor built in Servo Amplifier,
as Regenerative Resistor type set “built-in regenerative
resistor” to the amplifier exactly.
With this setting, it is decided that overheat protecting
detection of built-in regenerative resistor is effective or
ineffective. In case no regenerative resistor connection or
external regenerative resistor is selected, overheat
detection of built-in regenerative resistor will not function.
