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.

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

Wiring regenerative resistor correctly:
Connect regenerative resistor wires to P
