What to do
Check the external device.
Check setting of parameter
External event 4
source.
Check the external device.
Check setting of parameter
External event 5
source.
Check safety circuit connections. For
more information, see chapter The
Safe torque off function in the
Hardware manual of the drive and
description of parameter
indication run/stop
(page 180).
Check the value of parameter
Control board
supply.
Check the nominal motor values in
parameter group
99 Motor
Check that no external control system
is connected to the drive.
Cycle the power to the drive (and its
control unit, if powered separately).
Check that no operation limits prevent
the completion of the ID run. Restore
parameters to default settings and try
again.
Check that the motor shaft is not
locked.
Check the auxiliary code. The second
number of the code indicates the
problem (see actions for each code
below).
Check settings of parameters
Motor nominal current
and
Maximum
current. Make sure that
30.17
> 99.06.
Check that the drive is dimensioned
correctly according to the motor.
