Fault Description
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
value of full closed-loop exceeds
the specified limit.
The wiring connections of linear
and servo drive are in error.
The analog input voltage is higher
than the value of P1-83 over
50ms.
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.
