Number / Alarm Cause Counter-measure
A028
Diagnostics counter The position of an encoder (motor encoder or
external encoder) was incorrect for one or
more samplings. This can result from EMC
faults or a loose contact.
When faults start to occur at a certain rate,
fault message F51 is triggered by the
corresponding fault variable. For test purposes, fault message F51 can be
triggered with the setting P847=2 in order to
obtain more information about fault variable
r949.
All indices can also be monitored in r849 in
order to find out which diagnostics counter
counts the fault. If alarm A28 is hidden for this
fault, then the corresponding index in P848
can be set to 1.
A029
I2t motor The parameterized limit value for the I2t
monitoring of the motor has been exceeded. Motor load cycle is exceeded!
Check the parameters:
P382 Motor Cooling
P383 Mot Tmp T1
P384 Mot Load Limits
A032
PRBS Overflow An overflow has occurred during recording
with noise generator PRBS Repeat recording with lower amplitude
A033
Overspeed The positive or negative maximum speed has
been exceeded. - Increase relevant maximum speed
- Reduce regenerative load (see FD 480)
A034
Setpoint/actual value
deviation Bit 8 in r552 status word 1 of the setpoint
channel. The difference between freqeuncy
setpoint/actual value is greater than the
parameterized value and the control
monitoring time has elapsed. Check
- whether an excessive torque requirement is
present
- whether the motor has been dimensioned too
small.
Increase values P792 Perm Deviation Frq/
set/actual DevSpeed and P794 Deviation Time
A036
Brake checkback
"Brake still closed" The brake checkback indicates the "Brake still
closed" state. Check brake checkback (see FD 470)
A037
Brake checkback
"Brake still open" The brake checkback indicates the "Brake still
open" state. Check brake checkback (see FD 470)
A042
Motor stall/block Motor is stalled or blocked.
The alarm cannot be influenced by P805
"PullOut/BlckTime", but by P794 "Deviation
Time" Check
- whether the drive is blocked
- Whether the drive has stalled
A049
No slave
not Compact PLUS At serial I/O (SCB1 with SCI1/2), no slave is
connected or fiber-optic cable is interrupted or
slaves are without voltage. P690 SSCI AnaIn Conf
- Check slave.
- Check cable.
A050
Slave incorrect
not Compact PLUS At ser. I/O the slaves required according to a
parameterized configuration are not present
(slave number or slave type): Analog inputs or
outputs or digital inputs or outputs have been
parameterized which are not physically
present. Check parameter P693 (analog outputs), P698
(digital outputs). Check connectors
K4101...K4103, K4201...K4203 (analog inputs)
and binectors B4100...B4115, B4120...B4135,
B4200...B4215, B4220...B4235 (digital inputs)
for connecting.
A051
Peer baud rate
not Compact PLUS In a peer-to-peer connection a baud rate has
been selected which is too high or too
different. Adjust the baud rate in conjunction with the
SCB boards P701 SCom/SCB Baud Rate
A052
Peer PcD L
not Compact PLUS In a peer-to-peer connection, a PcD length has
been set which is too high (>5). Reduce number of words P703 SCom/SCB
PcD #
