7.2 Error list
The following table helps you with troubleshooting:
Code Error Possible cause Measure
– Communication
timeout
(motor stops, without
error code)
Missing connection
'
, RS
+, RS- between
MOVIMOT
®
and RS485
master
Check and establish the connection, espe-
cially ground.
EMC influence Check the shielding of signal cables and im-
prove, if necessary.
Incorrect type (cyclical) for
acyclical data traffic, the
protocol period between
the individual messages is
longer than the set timeout
interval. Check the number of MOVIMOT
®
drives con-
nected to the master. If the timeout interval is
1 s, for example, you can connect a maximum
of 8 MOVIMOT
®
drives as slaves for cyclical
communication.
Reduce message cycle, increase timeout in-
terval, or select message type "acyclic".
– Supply voltage not
present
(motor stops, without
error code)
DC link voltage too low,
Power off has been detect-
ed.
Check supply system cables and line voltage
for interruption.
– 24 V supply not
present
(motor stops, without
error code)
24 V supply voltage not
present. Check 24 V supply voltage for interruption.
Check 24 V supply voltage.
Permitted voltage: DC 24 V ± 25%,
EN 61131-2, residual ripple max. 13%
Motor restarts automatically as soon as the
voltage reaches normal values.
AUX power supply voltage
not available.
(only for MOVIMOT
®
with
AS-Interface)
Check AUX power supply voltage for interrup-
tion.
Check AUX power supply voltage.
Permitted voltage: DC 24 V ± 25%,
EN 61131-2, residual ripple max. 13%
Motor restarts automatically as soon as the
voltage reaches normal values.
01 Overcurrent in out-
put stage Short circuit on inverter
output Check the connection between the inverter
output and the motor as well as the motor
winding for short circuits.
Reset the error.
1)
04 Brake chopper Overcurrent in brake out-
put, resistor damaged, re-
sistance too low Check the connection of the resistor/replace it.
Short circuit in brake coil Replace brake.
06 Phase failure
(The error can only
be detected when the
drive is under load)
Phase failure Check the supply system cable for phase fail-
ure.
Reset the fault
