Operating Instructions
Description
In the following cases, the
safety option requests a
restart and failure acknowl-
edgement-signal:
1. The safety option is in
safety function pending-
state (Remark: Occurs only
if reset behaviour is set/
configured to 'manual')
2. After a power cycle with a
safety function
3. In PUST (power up self
test), if an external failure
occurred before power
cycle
4. When an external failure
occurred
5. When customisation was
aborted or completed
6. At the reception of a
general reset (required
after blank initial state or
in the customisation
state.)
The safety option indicates
that it is PUST State (Power
Up Self Test).
1. Ensure that no safe
function is active after a
power cycle.
A safety function is pending
at the start-up, if the
frequency converter was
powered down while a safety
function was active.
It is also pending, when the
frequency converter was
powered down while the
safety option has detected a
failure during an active safety
function.
The safety option requests a
'Restart and Failure
Acknowledge signal', which is
always required after a PUST
and when a safety function
gets released and is
configured to be confirmed
that the motor is able to run.
