Connect motor cable.
If the drive is in scalar mode and
nominal current of the motor is less
than 1/6 of the nominal output
current of the drive, set parameter
31.19 Motor phase loss to No action
[0].
Motor circuit fault due to
missing motor connection
(any of the three phases
not connected). In scalar
control mode, the drive
detects fault only when
the output frequency is
above 10% of the motor
nominal frequency. Con-
nect motor cable. If the
drive is in scalar mode and
nominal current of the
motor is less than 1/6 of
the nominal output cur-
rent of the drive, set para-
meter 31.19 Motor phase
loss to No action [0].
