Cause
Pre-heating is being performed Informative warning. Motor pre-heating is
No run enable signal is
received.
95.04 Control board supply
set to External 24V but no
voltage is connected to the
control unit.
Signal to rotate has not been
received within a fixed time
delay of 120 s.
Motor ID run will occur at next
start.
Motor ID run completed
successfully.
Safe torque off function is
active, ie. safety circuit
signal(s) connected to
connector STO is lost.
No more PFC motors can be
started because they can be
interlocked or in the Hand
mode.
All the motors in the PFC
system are interlocked.
The motor connected to the
drive is interlocked
(unavailable).
The software is not working
properly.
What to do

Check setting of parameter
enable 1 source. Switch signal on (e.g. in
the fieldbus Control Word) or check
wiring of selected source.
is Check the external 24 V DC power
supply to the control unit, or change the
setting of parameter 95.04.
Switch enable to rotate signal on (eg. in
digital inputs).

Informative warning.
Informative warning.
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 31.22 STO indication run/stop
(page 261).
Check that there are no interlocked PFC
motors, see parameters: 76.81...76.84. If
all motors are in use, the PFC system is
not adequately dimensioned to handle
the demand.
Check that there are no interlocked PFC
motors, see parameters 76.81...76.84.
Motor connected to the drive is
interlocked and thus cannot be started.
Remove the corresponding interlock to
start the drive controlled PFC motor. See
parameters 76.81...76.84.
Restart the control unit.
