Encoder communication circuit diagnosis

The on-site GOT identifies the cause of an alarm generated by communication with the
encoder
Challenges
The encoder is acting strange.
I need to bring a PC to check.

Machine diagnosis (friction estimation, vibration estimation)

The on-site GOT provides information on when to perform maintenance on components
such as ball screws and linear guides

Solutions
When an encoder communication alarm occurs, you can use GOT to diagnose and determine
whether the cause of the alarm is a servo amplifier failure or an encoder failure without preparing
a PC.

Solutions
Maintenance can be performed on the machine before it fails because the servo amplifier estimates
the friction and vibration of the drive unit, and GOT shows you a failure prediction warning.
