Cause
A follower drive has tripped.
No enable start signal
received.
No run enable signal is
received.
95.04 Control board supply
set to External 24V but no
voltage is connected to the
XPOW connector of the control
unit.
Motor ID run will occur at next
start, or is in progress.
Autophasing will occur at next
start.
Safe torque off function is
active, i.e. safety circuit
signal(s) connected to
connector XSTO is lost.
Control unit rebooted
unexpectedly.
The calculated parameter
checksum does not match any
enabled reference checksum.
Maximum number of cleanings
in defined time frame has been
exceeded.
U/f curve frequency points are
not defined in proper
ascending order.
Underload supervision signal
exceeded the defined
underload supervision limit.
Restart delay is active - The
drive start command is
inhibited for the time set in
parameter 74.21 Restart delay
time.
Overload supervision signal
exceeded the defined overload
supervision limit.
What to do
Check the auxiliary code. Add 2 to the
code to find out the node address of the
faulted drive.
Correct the fault in the follower drive.
Check the setting of (and the source
selected by) parameter
start command.
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.
