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.

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.

Regenerative power is too large.
Faulty wiring of built-in regenerative
resistor
Check wrong wiring and correct it.

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.

Caution
Regenerative resistor which is built in the amplifier of 15A
or 30A does not have a thermostat.
Alarm Code 55H (External error)
Checking The Selection of Active Condition under the external trip function, confirm
if the external trip function is active, and also which input is used. Confirm what
function is used for the general purpose input terminal in validity when external trip
is activated
