Check if:
• The drive is powered off.
• The drive is not ready.
The drive is starting up.
There are no active faults, and the drive is ready to operate.
There is no warning.
The drive is not ready to run. Check if:
• Safety configuration is needed.
• STO active or STO acknowledge is needed.
• IO Failure or IO Failure acknowledge needed.
• STO response is configured as fault (with application).
There are no active faults and the drive is ready to operate.
The drive is in a faulty state. The fault condition may have been
triggered due to 1 of the following reasons:
• Power unit and control connection failure
• Hardware or software errors in the drive
Additional information
The motor is running and no safety function is active.
STO feedback is de-energized.
STO is requested, and a safe state is reached.
STO state is reached and connection to all power units
is established. STO output is de-energized.
Safe inputs must have a validated configuration to
ensure that all power units have reached a safe input
state. The connected power units are a part of the con-
figuration, and without a validated configuration, the
safe input cannot assume to have a connection to all
power units established.
During software update, the state of the safe output is
not reliable. STO output is de-energized.
