Alarm Name
Phase C was not detected during the first two rotations after
the power supply was turned ON.
The magnetic pole could not be detected.
An overtravel signal was detected during magnetic pole
detection.
An attempt was made to detect the magnetic pole for the
high-speed winding or when changing the winding (for
motors with a winding selection).
Movement during magnetic pole detection reached or
exceeded the set value of Pn494.
The magnetic pole could not be detected.
The multiturn for the absolute encoder was not properly
cleared or set.
Communications between the SERVOPACK and the
encoder is not possible.
An encoder position data calculation error occurred.
An error occurs in the communications timer between the
encoder and the SERVOPACK.
Encoder parameters are faulty.
Contents of communications with encoder is incorrect.
Different multiturn limits have been set in the encoder and
the SERVOPACK.
Reception from the serial converter unit.
Timer for communications with the serial converter unit is
faulty.
Position error pulses exceeded parameter (Pn520).
Position error pulses accumulated too much.
After a position error pulse has been input, Pn529 limits the
speed if the SV_ON command is received. If Pn529 limits
the speed in such a state, this alarm occurs when the position
references are input and the number of position error pulses
exceeds the value set for parameter Pn520 (Excessive Posi-
tion Error Alarm Level).
The position error between motor and load is excessive.
Internal program error 5 occurred in the SERVOPACK.
Internal program error 6 occurred in the SERVOPACK.
Internal program error 7 occurred in the SERVOPACK.
Internal program error 8 occurred in the SERVOPACK.
The HWBB function signal input timing is faulty.
A power regeneration converter local bus WD alarm
occurred.
A communications error occurred during the power regener-
ation converter local bus communications.
The local bus is not connected.
