WARNING
Automatic restart!
Can result in death, serious injury, or property damage.
The motor switches on again when the following condition is met:
• the overload relay is switched from manual mode to automatic mode with the help of the
operator panel, and the pending control commands DO 0.0 / DO 0.1 of the higher-level
controller are executed again.
Manual switching from manual mode to automatic mode must not be used in applications
where there is a risk of serious injury to persons or substantial damage to property if the motor
starts up again unexpectedly.
Make sure that the machine danger zone is kept clear of people at the time of restarting.
Monitoring mode
The operator panel is always in monitoring mode as standard. The user can read the switching
states of the solid-state overload relay for IO‑Link and detect group errors.
