Cause
95.04 Control board sup-
ply is set to External 24V
but no voltage is connec-
ted to the control unit.
Signal to rotate is not re-
ceived within a fixed time
delay of 120 s.
Motor ID run will occur at
next start.
Motor ID run completed
successfully.
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 work-
ing properly.
What to do
Check the external 24 V DC power
supply to the control unit, or
change the setting of parameter
95.04.
Switch on the enable to rotate sig-
nal (eg. in digital inputs). Check
parameter 20.22 Enable to rotate.
Informative warning.
Informative warning.
Check safety circuit connections.
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 ad-
equately 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 in-
terlocked and thus cannot be star-
ted. Remove the corresponding in-
terlock to start the drive controlled
PFC motor. See parameters
76.81...76.84.
Restart the control unit.
