This system has various safety functions to ensure safe use.
10.1. Safety Functions
The safety functions can be classified into hardware monitoring and software monitoring.
Hardware monitoring
・ Power supply fuse
・ Output amplifier overheat
・ Motor overheat
(If output amplifier or motor overheat is detected, the amplifier output is shut down.)

Software monitoring
The controller status is always monitored by software and error notification is made if an abnormality
occurs.
Depending on the error type (priority), digital monitor I/O (2 bits) is used for this notification.
The details of an error can be checked by an RS-232C command.
See 10.2, "Errors" for the error details.
Note: The post-error system status and recovery method depend on the priority of the error.
See 10.2, "Errors."
Note: Temperature settings of the above hardware temperature monitoring and software
temperature monitoring differ. Usually, temperature monitoring of software operates first,
and it is set to carry out error input and servo off operations.
