Fault Messages
Fault Description
Emergency stop switch is
activated.
Reverse limit switch is activated.
Forward limit switch is activated.
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.
