Parameter Description Action Setting/ Default
Automatic Restart
P1210 = 6, Restart after
supply power brown/blackout
or fault (P1211 disabled):
The inverter will
acknowledge the faults
(F0003 etc.) at power on
after blackout or brownout
and will restart the drive. It
is necessary that the ON
command is wired via
digital input (DIN). Setting
6 causes the motor to
restart immediately.
P1210 = 7, Restart after
supply power brown/blackout
or fault (P1211 enabled):
This setting is for use
where an external bypass
system or process is
interlocked with a relay that
is set to
P0731/P0732=52.3 (fault).
The inverter functions the
same as P1210=6 (trip on
brownout, blackout or fault)
but uses P1211 and only
sets the fault bit
P0731/P0732=52.3 when
the specified number of
restarts defined in P1211
has expired. If no trip
occurs after 2 hours, the
fault counter is reset.

(Cont’d)
NOTES:
1. Auto restart requires a constant ON command (such as via a digital input
wire link).
2. P1200 flying start must be used in cases where the motor may still be
turning, such as after a brief input power break, or can be driven by the
load.
3. A supply power brownout is when the power is interrupted and reapplied
before the operator panel display has gone dark. It is a very short supply
power break where the DC link has not fully collapsed
4. A supply power blackout is when the operator panel display has gone
dark before the power is reapplied. It is a long supply power break where
the DC link has fully collapsed.
