Functional Safety Considerations
ATTENTION: Before maintenance work can be performed in Program mode,
the developer of the application must consider the implications of allowing
motion through motion direct commands and should consider developing logic
for run-time maintenance operations to meet the requirements of machine
safety operating procedures.
ATTENTION: Motion is allowed when motion direct commands are used in
Program mode and STO function is not available.
Motion direct commands issued when the controller is in Program mode causes
the drive to bypass the STO Active condition.
It is your responsibility to implement additional preventive measures to
maintain safety integrity of the machinery during execution of motion direct
commands in Program mode.
ATTENTION: To avoid personal injury and damage to equipment in the event of
unauthorized access or unexpected motion during authorized access, return the
controller to RUN mode and remove the key before leaving the machine
unattended.
