WARNING
UNINTENDED START
When the frequency converter is
connected to AC mains, DC supply,
or load sharing, the motor may
start at any time. Unintended start
during programming, service, or
repair work can result in death,
serious injury, or property damage.
The motor can start via an external
switch, a eldbus command, an
input reference signal from the LCP,
or after a cleared fault condition.
To prevent unintended motor start:
•
Disconnect the frequency
converter from the mains.
•
Press [O/Reset] on the
LCP before programming
parameters.
•
Fully wire and assembly
the frequency converter,
motor, and any driven
equipment before
connecting the frequency
converter to AC mains, DC
supply, or load sharing.
NOTICE
If the specied number of
automatic resets is reached within
10 minutes, the frequency
converter enters [0] Manual reset
mode. After the manual reset is
performed, the setting of
parameter 14-20 Reset Mode reverts
to the original selection. If the
number of automatic resets is not
reached within 10 minutes, or
when a manual reset is performed,
the internal automatic reset
counter returns to 0.
Select the reset function after tripping.
Once reset, the frequency converter can
be restarted.
[0] * Manual reset Select [0] Manual reset, to perform a
reset via [Reset] or via the digital inputs.
[1] Automatic reset
