List of Error Codes
Appendix D
(2) When multiple warnings occur, the warning codes are displayed on the front panel in the order of
their priority (shown above). The value read from the network is set.
List of G-series Alarm Displays
The Servo Drive has built-in protective functions. When a protective function is activated, the Servo Drive turns
OFF the alarm output signal (ALM) and switches to the Servo OFF status.
The alarm code will be displayed on the front panel.
Alarm type
Description
---
Protective function that allows the alarm to be reset, and leaves record in the alarm history.
PR
Protective function that does not allow the alarm to be reset, and requires the control power supply
to be turned OFF and turned ON again after resolving the problem.
X
Protective function that does not leave record in the alarm history.
