Software
An 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.
5.2.2. Conveyor Suttle ,Width and Rail -Axis
Since this product is equipped with the LED to indicate the alarm state of the amplifier
itself, occurrence or not of failures can be checked immediately. The failure cause can be
found out by the number of times of flickering of the LED or by the alarm code through
the PC I/F. Indicated below are the failure causes and corrective measures Meanwhile,
contact us if it is not possible to make restoration to the normal state
