Chapter 9 Troubleshooting ASDA-B2
9-2 Revision September 2013
Fault Messages
Display Fault Name Fault Description
Encoder output error The encoder output exceeds the rated output frequency.
Serial communication
error
RS232/485 communication is in error.
Serial communication
time out
RS232/485 communication time out.
Reserved Reserve
Input power phase loss One phase of the input power is loss.
Pre-overload warning
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.
Encoder initial
magnetic field error
The magnetic field of the encoder U, V, W signal is in error.
Encoder internal error
The internal memory of the encoder is in error. An internal
counter error is detected.
Encoder data error
An encoder data error is detected for three times.
Motor internal error
The setting value of the encoder is in error.
Motor internal error
The encoder U, V, W signals are in error.
Motor internal error
The internal address of the encoder is in error.
Motor protection 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.
U,V,W, GND wiring
error
The wiring connections of U, V, W (for servo motor output)
and GND (for grounding) are in error.
Motor temperature
error
Motor is working under temperature over 105°C (221°F).
Excessive encoder
output error
The encoder output errors or output pulses exceed hardware
tolerance.
Motor temperature
warning
The temperature of motor is over 85°C (185°F).
DSP firmware upgrade
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.
NOTE
1) If there is any unknown fault code that is not listed on the above table, please inform the
distributor or contact with Delta for assistance.
