Fault Messages
Fault Description
The temperature of IGBT is over high.
EE-PROM write-in and read-out is in error.
The encoder output exceeds the rated output
frequency.
RS-232/485 communication is in error.
RS-232/485 communication time out.
One phase of the input power is loss.
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.
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.
The position control deviation value of full closed-loop
exceeds the specified limit.
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
servo drive.
