Fault Messages
The encoder output exceeds the rated output frequency.
RS232/485 communication is in error.
RS232/485 communication time out.
Reserve
To warn that the servo motor and drive is going to overload.
This alarm will display before ALM06. When the servo motor
reach the setting value of P1-56, the motor will send a
warning to the drive. After the drive has detected the warning,
the DO signal OLW will be activated and this fault message
will display.
The magnetic field of the encoder U, V, W signal is in error.
The internal memory of the encoder is in error. An internal
counter error is detected.
An encoder data error is detected for three times.
The setting value of the encoder is in error.
The encoder U, V, W signals are in error.
The internal address of the encoder is in error.
In order to protect the motor, this alarm will be activated
when the setting value of P1-57 is reached after a period of
time set by P1-58.
The wiring connections of U, V, W (for servo motor output)
and GND (for grounding) are in error.
Motor is working under temperature over 105°C (221°F).
The encoder output errors or output pulses exceed hardware
tolerance.
The temperature of motor is over 85°C (185°F).
EE-PROM is not reset after the firmware version is upgraded.
This fault can be cleared after setting P2-08 to 30 first, and
then setting P2-08 to 28 next and restarting the ervo drive.
