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

Reduce voltage to within allowable
range.

Faulty wiring of connector CND, or
Inner regenerative circuit does not
function.
Wiring regenerative resistor correctly:
Connect regenerative resistor wires to P
and Y terminals of connector CND.
When external regenerative resistor is
used, check wiring and resistance
value. Replace Servo Amplifier if
malfunction persists.
