CHAPTER 4 APPENDICES
Appendix 3. Alarm Messages
The difference input for one of the A, B or Z
phase signals of the detector installed on the
motor end has become "H" or "L".
(Software detection in the B Series.)
The difference input for one of the A, B or Z
phase signals of the detector installed on the
machine end has become "H" or "L".
(Software detection in the B Series.)
An error occurred in the LSI operation.
A motor cable ground fault was detected.
The absolute position data in the absolute
position detector was lost.
A power module error occurred in an axis for
which the rotary switch on the 2-axis integrated
drive unit was set to F to exclude from control.
The CPU in the absolute position detection linear
scale is not operating correctly.
The scale in the absolute position linear scale
moved at a speed equal to or higher than
45mm/s during initialization.
(Alarm output from inside the linear scale.)
A hardware error occurred in the absolute
position detection circuit in the absolute position
linear scale.
(Alarm output from inside the linear scale.)
A hardware error occurred in the relative position
detection circuit in the relative position linear
scale.
(Alarm output from inside the linear scale.)
An error occurred in the CPU in the serial
encoder installed on the motor end.
(Alarm output from the detector.)
Deterioration of the LED in the detector was
detected.
An error was detected in the position per rotation
in the detector.
Communication with the detector was cut off, or
the communication data was abnormal.
Overheating of the regenerative resistor was
detected.
The motor speed reached 1.2 times the rated
motor speed.
An overcurrent was detected in the IPM used in
the servo drive main circuit section.
The PN bus voltage is more than 400V.
A CRC error occurred in the communication data
from the NC.
