Description of Parameter
This determines how the
drive starts the motor. This is
a useful setting if the drive
occasionally starts when the
motor is already spinning.
Parameter options:
0 – Disable. Wait for the
motor to stop spinning
before next start.
1 – Speed search, starting
from maximum frequency
(normally 60Hz).
2 – Speed search, starting
from motor start frequency
(normally 0.5Hz).
3 – Speed search, starting
from minimum frequency.
When a restart occurs after
a fault, the drive starts this
internal time clock and
counts the number of faults
that occur within this time
period. If the number of
faults do not exceed the
number recorded in the 07-
11 parameter, the time clock
and fault are reset back to
zero.
When the number of faults
exceed the 07-11 parameter
value, the drive faults and
stops, requiring user
intervention.
