CautionAn alarm which has a “ * “ mark at the side of the Alarm Code No.
in the above table cannot be cleared. In such case, turn the power
off and then on again to release the alarm if the machine is in
normal condition
When an error occurs in the internal control circuit of the Servo-
Amp. due to excessive noise, etc., the following alarm codes may
be displayed.
In this case, immediately turn off the power and check both the
cable wiring and the connection of the frame ground
If any alarm that is not included in the above alarm code table
occurs, input the parameters of the Servo-Amp. again using the
exclusive program. Next, turn the power off and then on again,
and check the machine to determine if there still is a problem
If the alarm still continues after taking the above third measure, it is
caused by a damaged amplifier in most cases. In this case, change
the Servo-amp.
