Caution

 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.
