Servo Alarm
Cause and Remedy
Converter bus voltage exceeded 400 V DC.
(Cause 1) Regenerative brake option is not used.
(Remedy) Use the regenerative brake option.
(Cause 2) Though the regenerative brake option is used, the
parameter No. 2 setting is "00 (not used)".
(Remedy) Make correct setting.
(Cause 3) Lead of built-in regenerative brake resistor or
regenerative brake option is open or disconnected.
(Remedy 1) Change lead.
(Remedy 2) Connect correctly.
(Cause 4) Regenerative transistor faulty
(Remedy) Change servo amplifier.
(Cause 5) Wire breakage of built-in regenerative brake resistor
or regenerative brake option
(Remedy 1) For wire breakage of built-in regenerative brake
resistor, change servo amplifier.
(Remedy 2) For wire breakage of regenerative brake option,
change regenerative brake option.
(Cause 6) Power supply voltage high
(Remedy) Review the power supply.
33 Overvoltage
(Cause 7) Ground fault occurred in servo amplifier output
phases U, V, and W.
(Remedy) Correct the wiring.

Servo Alarm
Cause and Remedy
Bus cable is faulty.
(Cause 1) Bus cable disconnected.
(Remedy) Connect correctly.
(Cause 2) Bus cable fault
(Remedy) Change the cable.
(Cause 3) Noise enter bus cable.
(Remedy) Take measures against noise.
(Cause 4) Termination connector disconnected.
(Remedy) Connect termination connector.
34 CRC error
(Cause 5) The same No. exists in the servo amplifier side axis
setting.
(Remedy) Set correctly.
Input frequency of command pulse is too high.
(Cause 1) Command given is greater than the maximum speed
of the servo motor.
(Remedy) Review operation program.
(Cause 2) Noise entered bus cable.
(Remedy) Take action against noise.
35 Command
frequency error
(Cause 3) Servo system controller failure
(Remedy) Change the servo system controller.

Cause and Remedy
Bus cable or printed board is faulty
(Cause 1) Bus cable is disconnected.
(Remedy) Connect the connector of the bus cable.
(Cause 2) Bus cable fault.
(Remedy) Change the cable.
(Cause 3) Printed board is faulty.
(Remedy) Change the servo amplifier.
36 Transfer error
(Cause 4) Termination connector disconnected
(Remedy) Connect termination connector.
Parameter setting is wrong.
(Cause 1) Servo amplifier fault caused the parameter setting to
be rewritten.
(Remedy) Change the servo amplifier.
37 Parameter error
(Cause 2) There is a parameter whose value was set to outside
the setting range by the controller.
(Remedy) Change the parameter value to within the setting
range.
