Safety warnings and precautions
WARNING
The TJ1 will turn off the WDOG when its self-diagnosis function
detects any error.As a countermeasure for such errors, external
safety measures must be provided to ensure safety in the system.
WARNING
Provide safety measures in external circuits, i.e., not in the Tra-
jexia Motion Controller (referred to as "TJ1"), in order to ensure
safety in the system if an abnormality occurs due to malfunction of
the TJ1 or another external factor affecting the TJ1 operation.
Not doing so may result in serious accidents.
